->'''''G'''''''eneric'' '''''U'''''''niversal'' '''''R'''''''ole'' '''''P'''''''laying'' '''''S'''''''ystem''

In 1986, Creator/SteveJacksonGames released the first edition of the ''GURPS'' Basic Set. Although the system has roots in Jackson's ''Melee'', ''Wizard'', and ''TabletopGame/TheFantasyTrip'', ''GURPS'' was developed in direct response to Hero Games' ''TabletopGame/{{Champions}}: The Super Roleplaying Game'' (the original PointBuy game). The name comes from both Steve Jackson's description of what he wanted and the in-house code for the project, "The Great Unnamed Role Playing System". However, when the time came to release the product, they had not been able to come up with a better name for it.

As a generic system, ''GURPS'' has no inherent story or background, although a number of settings have been developed and published specifically for the system, and others have been adapted; see TabletopGame/GURPSSettings.

For those curious about where ''GURPS'' fits in the taxonomies of game mechanics, ''GURPS'' is [[PointBuildSystem point-based]] and [[SkillScoresAndPerks skill-based]] rather than [[ClassAndLevelSystem level- and class-based]]. All tasks are resolved by rolling three six-sided UsefulNotes/{{dice}}, creating a bell-curve of probability instead of a flat line of equal chance.[[note]]This serves to partially counteract MinMaxing by adding a sort of "diminishing returns" logic to one's probability of success, since past a certain point each increase in skill level gives a smaller boost to the success rate than the one before.[[/note]] Success is awarded if the total of the die roll is equal to or less than a target number, usually a character's skill level. The difficulty of a task is represented by a modifier to the character's skill level, and not by the target number itself. All modifiers can only apply to that target number, and never to the number rolled on the dice.

In combat, each round represents one second, which is a point of contention among people who argue the merits of roleplaying systems. If you want to do anything in combat that's more complex than moving and attacking, ''GURPS'' will require you to describe your tactics in terms of several successive one-second-long maneuvers, and then go through several rounds of combat before you discover what the results are. It can kind of interrupt the flow if you want to play an ''TabletopGame/{{Exalted}}''-style game full of [[RuleOfCool elaborate stunts]]. The Fourth Edition supplement ''GURPS Action'' was created to remedy this.

''GURPS'' has been described as a "simulationist" system, because it includes lots of rules that tell you what's happening in the game-world without much affecting the outcome of the relevant event. For example, when an attacker succeeds at his roll to hit, the defender always gets to choose how to defend and makes the appropriate defense roll (unless it was a critical hit or a surprise). The defense could be handled as penalties applied to the attack roll, and the odds of dealing damage would be the same--but in that case, should your opponent avoid taking damage, you wouldn't know if it was because you missed entirely, or nearly hit but the defender dodged, or hit too soft to do any damage, or hit hard enough to do damage but your opponent is too much of a badass to notice. This is helpful to game masters narrating the combat because it tells them exactly what to narrate, but it does take longer.

Perhaps the best feature of ''GURPS'' is the huge number of {{Sourcebook}}s that have been written for it. Pick any genre or topic, and you will probably find at least one ''GURPS'' book covering it (often available in PDF rather than print form these days). Broad categories are covered in genre books; specific settings may receive [[TabletopGame/GURPSSettings their own books]]. In addition to suggestions and notes regarding the topic of the {{Sourcebook}}, each volume invariably includes additions to and errata for the basic rules set.[[note]]With the release of 4th ed., sourcebooks shifted to showing applications and examples of existing Basic Set rule rather than inventing new rules whole cloth. However, rules like Styles, Social Engineering mechanics, and Power Modifiers push the envelope, and several popular books like Spaceships, Ritual Path Magic, and Technical Grappling still do introduce new/optional rules.[[/note]] This has led people to ask why they should buy a so-called "universal system" that requires the purchase of a new rulebook every time the players wish to use that system to play in a new genre. Because of this, ''GURPS'' is often compared unfavorably with the TabletopGame/HeroSystem, a universal gaming system whose sourcebooks and supplements have never had to add new rules to the Core Set -- though the 4th edition evolution has made such additions less extensive.

On the other hand, new rules aside, many of the supplements are useful enough as setting sourcebooks that people using other {{Game System}}s will occasionally buy them as references; this was, in fact, part of the original mission statement for the game and the reason the "U" stands for "Universal". The opposite is also true; with a little work, most game worlds can be converted to ''GURPS'', usually with an increase in utility and flexibility. The intention was that by building the game around "real world" units of measurement instead of "rounds" and "hexes", it would be easier for people using other systems to make use of the information in the supplements. Of course [[CreatorProvincialism "real world" in this context means the USA]]; pounds, feet, yards as originally developed in the UK (international editions, however, are metricated). ''GURPS TabletopGame/{{Traveller}}'' subjects the previously-metric Third Imperium to this CulturalTranslation (though the original was also American) on the grounds of "fitting in with existing products". Some 3rd edition products would [[UnitConfusion randomly throw in some metric units anyway]], because trying to use two unit systems at the same time [[http://www.cnn.com/TECH/space/9909/30/mars.metric.02/ always works]]. As of the fourth edition, official conversions from and to metric units are printed at the beginning of the basic set.

Several ''GURPS'' supplements have their own pages; [[TabletopGame/GURPSSettings see here]] for a list.
----
!!GURPS provides examples of the following tropes:
(Note: Tropes covered in specific supplements may be discussed on those books' pages.)

* AbsurdlyPowerfulStudentCouncil: Discussed in Pyramid 107: [[MonsterOfTheWeek Monster Hunters]] III as an alternative to typical school structure.
* {{Acrofatic}}:
** Fat characters have no penalty to dexterity, speed, or Acrobatics skill. They also float well. However, their maximum Health is limited if sufficiently fat, which affects speed slightly, making it more expensive for them to be fast.
** In 3rd Edition and before your extra weight is counted as part of your character's carrying encumbrance, which does provide penalties to movement and a number of skills. These rules were reworked in the Fourth Edition.
* ActualPacifist: The Pacifism (Total Nonviolence) disadvantage.
* AdjectiveAnimalAlehouse: In the ''GURPS Fantasy'' (3rd edition) supplement ''Harkwood'', the Clumsy Lion Inn is located halfway between Castle Harkwood and Harkwood Town.
* AffectionateParody: ''Cliffhangers'', ''Atomic Horror'' and ''TabletopGame/TalesOfTheSolarPatrol'' all deal with pulp genres and old-fashioned SF in a tongue-in-cheek but affectionate way.
* AfterTheEnd:
** ''TabletopGame/GURPSReignOfSteel'' takes place in the aftermath of a RobotWar.
** ''GURPS [=Y2K=]'' is a good resource for post-apocalyptic and apocalyptic scenarios in general.
** The most recent "quick play" series devoted to post-apocalyptic games is actually named ''GURPS After the End'', displacing ''[=Y2K=]'' as go-to material.
** The most common outcome of the tables for generating new worlds in ''TabletopGame/InfiniteWorlds'', after just slightly different "modern world", is "modern post-apocalypse", followed by "early 20th century post-apocalypse". You are more likely to get those, than, say, all of the wacky settings the book is famous for ''combined''.
* TheAgeless: Unaging. This means only that the character will never grow older or die of old age; it confers no resistance to disease or harm. Other forms of immortality require additional powers.
* AllSwordsAreTheSame: The basic set plays this straight, grouping various similar kinds of weapons together. In the ''Martial Arts'' and ''Low-Tech'' books, however, weapons are only grouped together if they are completely identical, like a Japanese yari and a generic spear.
* AncientConspiracy: More than one sourcebook has detailed the workings of TheIlluminati.
** ''GURPS Illuminati'' is more like a genre book than a worldbook, detailing the various ways the GM could use an AncientConspiracy to drive a plot and organize a campaign.
** ''TabletopGame/ConspiracyX'' in its second edition is a third-party series of ''GURPS'' sourcebooks.
** ''GURPS Cabal'', a setting for third-edition ''GURPS Horror'', is a magical ConspiracyKitchenSink.
* AnnoyingArrows: [[AvertedTrope Averted]], arrows do a lot of damage, and a good archer has a decent chance of bringing down even really tough fighters with one or two shots.
* ArabianNightsDays: ''GURPS [[http://www.sjgames.com/gurps/books/arabiannights/ Arabian Nights]]'' is about roleplaying within this trope, while some lands in the world of ''GURPS TabletopGame/{{Banestorm}}'' reflect it.'' GURPS TabletopGame/CastleFalkenstein: [[http://www.sjgames.com/gurps/books/ottoman/ The Ottoman Empire]]'' is about a version of the Ottoman Empire, in a GaslampFantasy world, that's very heavy on the Arabian Nights elements. And a few of the universes described in ''GURPS TabletopGame/InfiniteWorlds'' encompass or at least reference the trope.
* ArbitraryGunPower: One of the most systematic aversions possible. The closest anyone been able to come to divining the formula used by the authors goes on for [[http://www.sjgames.com/pyramid/sample.html?id=2794 pages]].
* ArmorIsUseless:
** One of the main complaints about the 4th edition relates to the insistence of this trope in high TL settings. The rules favour heavy-hitting weapons that are just impossible to block, and stealth technology as a means to avoid being hit, rather than anything providing the ability to withstand said hit.
** Spaceships, at least in 4th edition, tend to carry weapons that massively overwhelm the armor on other craft of their own size or smaller. For example, at [=TL10=] a 1000 ton ship can carry enough particle beams in one design section to destroy all but the most heavily armored 1000 ton ships in a single turn.
** ''Supers'' gives the Nonprotective Clothing {{Perk}}, which zigzags this: The player is allowed to wear clothing even if their natural armor would otherwise prohibit it, but it never gives any defensive abilities, even if wearing full plate armor.
* ArmyOfTheAges: Eternity's Rangers in ''GURPS Time Travel''.
* ArrangedMarriage: ''Social Engineering'' has several mechanics related to this. Some arranged marriages are [[AltarDiplomacy political alliances]] and use those rules, while some are effectively courtships of the bride's parents. A normal arranged marriage is mechanically similar to a job, with a roll for the NPC spouse's loyalty, while a ''forced'' marriage is a form of slavery and uses those loyalty rules.
* ArsonMurderAndJaywalking: The Nonprotective Clothing {{Perk}} from ''Supers'' says that it can benefit a super by preserving their decency[[note]]The perk allows one to wear purely cosmetic clothing when their natural armor would otherwise prevent anything over it[[/note]], [[ClarkKentOutfit conceal their secret identity]], or have pockets.
* ArtisticLicenseEconomics: Largely averted. Unlike in some games, a character's Wealth level is acknowledged and has real effects in game. The default is "Average", but you can take less (down to "Dead Broke") as a Disadvantage, and anything from "Comfortable" up to "Multimillionaire" as an advantage. How ''much'' more? Theoretically, as long as your character survives and earns points, ''unlimited'' levels of wealth are possible. Of course, there are some issues: If you take below-average Wealth, your character is stuck in PerpetualPoverty until you earn enough points to buy off the Disadvantage. No matter how much money they acquire in any given adventure, the GM ''must'' find a way to take it away. This can be interesting for both players and GM when, for instance, a party of varying Wealth levels finds the TreasureRoom. The converse is also true; if you've spent valuable character points to be Fiction500 rich (at least 150 character points in a game where most characters start with 100 total), a worldwide depression isn't even going to faze your character. Unless of course your [[KillerGM friendly neighborhood GM]] [[TheGMIsACheatingBastard decides it should....]] Finally, both Disadvantage and Advantage Wealth can be rendered meaningless when your character ventures into another of the ''TabletopGame/InfiniteWorlds''. Even there, though, a good GM will find a way to enforce both Disadvantage and Advantage, eventually.
* ArtisticLicenseMartialArts: The ''GURPS Martial Arts'' supplement (being as detail-oriented and versatile as is usual with the system) divides each martial arts style into “realistic” and “cinematic” versions, the latter requiring significant expenditure of character build points on exotic training and granting access to weird and fancy moves and quasi-supernatural effects. The Classic Edition even had special cinematic rules many of which reappeared in the next edition:
** Bulletproof Nudity: Less clothing makes it harder to be hit.
** Cannon Fodder: Minor [=NPCs=] fail all defense rolls and collapse if any damage gets through DR.
** Cinematic Explosions: Explosions do no direct damage though they do disarray clothing, blacken faces, and (most importantly) cause knockback.
** Flesh Wounds: Ignore all but 1 HP (or FP) of damage... at the cost of one unspent character point
** [[BottomlessMagazines Infinite Ammunition]]
** [[MookChivalry Melee Etiquette]]
** TV Action Violence: If struck by a potentially lethal attack (including a rapid-fire attack that inflicts multiple hits), the hero can choose to convert his failed defense roll into a success. This costs him 1 FP and he loses his next turn.
** Chambara Fighting Rules
** Exploding Eyeballs: Explosive decompression results in a bloody mess.
** Firecrackers and Hand-held Nukes: Opposing-force grenades make noise and smoke, but do only sartorial damage while friendly-force grenades are selective regarding the damage they do.
** Gun Control Law: The enemy will rarely use guns...even when they have them on their person.
** Hollywood Automatic Weapons: opponents haven't conceptualized aiming, especially when it comes to groups and all burst fire counts as a snap shot, never getting an Accuracy bonus.
** Imperial Stormtrooper Marksmanship Academy: the bad guys never hit with the first shot or burst of automatic fire.
** Martial Artists Anonymous: Every NPC the characters encounter will have some martial art training in the expert or better range.
* AttackFailureChance: Guns will misfire on a bad roll; this becomes more likely if the weapon is not cleaned regularly or is poor quality. Shooting without pausing can cause the same problems but heavier barrels warp more slowly and cooling systems allow for basically unlimited fire so long as they work.
* AttackReflector
** The default Reflective Damage Resistance will actually reflect punches back at the enemy just as well as lasers. But because it's ''GURPS'' someone can simply overpower it if you're too far out of your league.
** The Reverse Missiles spell, which (as the name suggests) only works on projectile attacks. It causes them to rebound and hit the attacker launching them.
** The ''Challenge'' magazine #47 article "The Ultra Tech File" had a number of items that couldn't fit in the ''Ultra Tech'' supplement. One of them was the Laser Reflector, a computer-controlled mirror used in laser surveying that could be used to reflect an incoming laser beam back at its source.
** 3rd Edition supplement ''Compendium I''. When a character has the advantage "Reflection", some of the damage that hits them bounces back and hits the attacker.
** ''Voodoo: The Shadow War'' supplement. The Reversal of Fortune protection ritual can bounce back cause an attacking ritual and cause it to affect the attacker instead of the target.
* AuthorAppeal: In any setting book by David Pulver, there will be an option to play as a CatGirl. Though in ''TabletopGame/GURPSReignOfSteel'', that requires a campaign in which you can play a “Pantera” biological android, constructed and trained to hunt and kill humans.
* BackgroundMagicField: In the standard magic system, the term "mana" refers to this, as opposed to a character's personal store of [[{{Mana}} magic points]]. Variant magic systems sometimes have other energies that fill the same purpose (such as "sanctity" for divine spellcasters).
* BadassNormal: High point characters with no supernatural and/or exotic advantages will inevitably fit this trope, though up to a point increasing the grittiness of the rules can limit it.
* BattleStrip: Covered by an optional rule called "Bulletproof Nudity".
* BerserkButton: There are multiple ways of giving your character one, most built around the disadvantage [[ExactlyWhatItSaysOnTheTin Berserk]].
* BigEater: Any character with the Increased Consumption and[=/=]or Gluttony disadvantages.
* BlackComedy: ''Realm Management'''s descriptions of conformity ratings gives three examples for Rating 6: A HiveMind, TheEvilsOfFreeWill, and ''Franchise/TheSmurfs''.
* BlobMonster:
** ''GURPS Dungeon Fantasy'', being an homage to old-school D&D, has a whole supplement of them: ''Dungeon Fantasy Monsters 2: Icky Goo''.
-->''Goo lacks most of the weaknesses of complex organisms that have internal organs, eyeballs, debts, and regrets.''
** In ''GURPS Monsters'', the Woodbury Blob is four foot wide (and tall, and thick), weighs 500 pounds, and is made up of amorphous living protoplasm. It eats by flowing over a living creature and absorbing it into its own body. It's almost ImmuneToBullets, which will make it a challenge to destroy.
* BloodBath: Vampires in the 3rd edition version of ''GURPS Fantasy'' can only heal their injuries by bathing in blood.
* BoldInflation: The publisher's official style guide notes that the game's title should be bold, italicized and all caps ('''''GURPS'''''); bold italics are also required for supplement titles, so long citations of the game’s own books can get this look.
* BornLucky: The Serendipity advantage grants happy coincidences, Luck allows rerolls and is noted in a few places as being pseudo-realistic for highly skilled people, and Super Luck gives the power to completely dictate the outcome of a single action.
* BulletProofFashionPlate: One possible use of the Shtick perk.
* CastFromStamina: Fatigue Points (FP) are based on the Health stat, and the default magic system has spells drain a certain amount of FP when cast or maintained. CastFromHitPoints is also an option, though it penalizes the skill roll while doing so, and there is a new advantage called Energy Reserve introduced in ''GURPS Powers'' that allows a spellcaster to use a separate energy source which is not impacted by health or strength and cannot be externally depleted by enemy attacks. Energy Reserve refills simultaneously with Fatigue Points, and so a wizard who has it is likely to mix both for the sake of efficiency.
* CavemenVsAstronautsDebate: The system is great for resolving these, although it will also create zillions of disagreements about what kinds of knives the cavemen have access to.
* CelibateHero:
** The Vow of Chastity can be this or a ChasteHero, depending on what other disadvantages are taken.
** A common aspect of some Codes of Honor.
* ChandelierSwing: The 3rd edition supplement ''Swashbucklers'' had extensive rules on swinging from chandeliers.
* ChaoticStupid: The Trickster disadvantage can cause this.
* CharacterCustomization: The game is constructed in such a fashion that you can make ANY CHARACTER as long as you can quantify what they can do. One famous example is the "[[http://forums.sjgames.com/showthread.php?t=31887 intelligent blueberry muffin]]".
* ChunkySalsaRule: If a character is damaged to -10x [[HitPoints HP]], they are not only dead (which occurs automatically at -5x HP if they don't die sooner) but destroyed. Exactly what this means depends on the source of the damage, from total incineration or dissolution for fire or acid, to merely being very very much pincushioned by arrows. This will often preclude means of resurrection that require a recoverable body.
* ClarkKenting: The "Masked" perk.
* ClapYourHandsIfYouBelieve: True Faith prevents anything "evil" from coming within a yard of you.
* {{Clockpunk}}: The TropeNamer, according to Website/TheOtherWiki.
* CloudCuckooLander: The highest level of Delusion makes you into this.
* ColonizedSolarSystem: In the ''Terradyne'' setting, the Moon has a pressurized city (Luna City) which is the capital of the titular MegaCorp turned empire. This setting was effectively replaced by TabletopGame/TranshumanSpace in 2002.
* CombinatorialExplosion:
** The treasure tables in the splatbooks aren't unusually long, but there are a lot of modifiers that can be applied to said treasure, and those modifiers can usually be stacked. So a generic "armor table" extends to cover helms, animal armor, and everything else that might protect your skin.
** The stand-out example of a combinatorial multiplier is GURPS' massively excessive number of hit locations, which go down to individual fingers and consider the head, the eyes, and the brain to be different 'targets', for instance. (Though using hit locations ''at all'' is strictly an optional rule, and even the most nit-pickingly detailed 4th edition games will rarely feature more than a dozen possible locations.) This adds up quickly to potentially over fifty hit locations per person, which multiplies the entire armor table directly (with rules causing armor for various locations to be altered with different values), weapons (with various types having different modifiers for different hit locations), and pretty much the entire power list and combat-applicable skill table, and to some extent even the health table. There is a reason most games run along the lines of [[ObviousRulePatch "all armored jackets have sleeves of the same armor value" and "there are no such things as fingerless gloves"]].
** The Dungeon Fantasy supplement on treasure claims to have '''eighty trillion''' possible treasures. Accomplished by having each table tell the GM to select another table to roll on.
** ''Powers'' adds several pages of generic modifiers that cause the same effect with advantages.
* TheConspiracy: Steve Jackson Games is quite big on conspiracy gaming in general, and ''GURPS Illuminati'' is an invaluable resource when it comes to such games.
* ConspiracyTheorist: There's a skill for this.
* ContrivedCoincidence: Serendipity lets you, the player, specify a random event that would be helpful to you, the character, and have it happen. Likewise, Gizmo lets you ''just happen'' to have brought the right gear for the problem in hand — while Cursed is a disadvantage for people who suffer from ''bad'' coincidences. Such features are there to let you play the sort of fictional characters who seem to be pawns of fate.
* CoolSpaceship: The ''Spaceships'' series is all about creating these and has a large number of worked examples. For bonus points, [[http://forums.sjgames.com/showpost.php?s=e12f630822e2a2d61405a577c9c98294&p=2324289&postcount=6 it actually follows the rocket equation assuming you stick with the realistic engine types.]]
* CrazyPrepared:
** You can make character sheets for just about anything, like plants and planets. Some [=GMs=] like to do this for pretty much every obstacle the players might encounter. There are also Techniques, a way to brush up on a specific aspect of a skill; meticulous players can use these to "buy off" any penalty they might have to roll against.
** Gizmos can be used to retroactively become CrazyPrepared.
** A good roll against Tactics skill at the start of a battle means your character thought ahead, so you get an advantageous starting position.
** The Traps skill is just as good for ''setting'' traps as disarming them.
* CriticalExistenceFailure
** Averted. When you're below 1/3 HP, you can only move half as fast as usual, which makes you easier to hit. When you're below 0 HP, you have to roll your health ''every turn'' to do anything at all without collapsing. But game masters who want cinematic hack'n'slash games often just ignore this when it's inconvenient.
** Affliction: Heart Attack will make your character roll against HT. If your character fails, he or she dies in a few minutes. Within those minutes, he or she can be resuscitated... unless the affliction was Irresistible.
* CrystalSkull: In the ''Warehouse 23'' supplement.
* DamageReduction:
** The primary benefit of wearing/installing armor is reducing damage received when your other defences fail you. DR is also an advantage that can be purchased by characters, races, etc. One to three points of damage reduction seems to be the "realistic" limit for natural DR, possessed by real animals with thick hides/scales or purchasable by players without needing specific GM approval. Previous versions featured the Toughness advantage, a more expensive DR with a two point {{Cap}} specifically for human use, with the base advantage restricted to supers or races.
** Armor piercing attacks generally take the form of a divisor, reducing DR by half or more.
** The Damage reduction advantage also has a host of options to modify its function, in particular conjunction with DamageTyping. The advantage could be used to simulate anything from thick skin to magical resistance against a given element to an ablative force field that needs recharging.
* DamageTyping:
** Nearly every possible way it could be handled. There's [[KillItWithFire burning]], [[HollywoodAcid corrosion]], [[BludgeonedToDeath crushing]], [[AbsurdCuttingPower cutting]], [[InstantDeathStab impaling]], [[ArbitraryGunPower small piercing, piercing, large piercing, huge piercing]] and [[PerfectPoison tox]][[AtomicHate ic]]. All damage types will end up reducing the victim's hit points—you don't have to track damage separately for the different types—but some damage types give a multiplier to the amount of damage that gets through the victim's armor. Further, some kinds of armor give varying amounts of protection depending on what sort of damage they are protecting from. On top of that there are also attacks that damage fatigue points, making characters more exhausted rather than damaged. Then after all of that it also handles radiation damage as a sort of hybrid between the other types of damage. In short, rules for every possible way one could cause damage and different ways characters are expected to react to them.
** On top of actual damage, you have things like Binding, [[LifeDrain Leech]], [[BlindedByTheLight Obscure]], Fatigue damage, and all flavors of [[StatusEffects Afflictions]].
** The Supernatural Durability Advantage is basically custom made for this trope.
* DanceBattler: The Dancing skill can be used (in some games) to feint or even kick enemies in melee combat.
* {{Determinator}}: Stronger characters in good physical condition can take enough damage that would kill lesser characters outright.
* DevolutionDevice: In ''GURPS Warehouse 23'', one of the devices stored in the Warehouse is the Devolvo Ray. It fires a beam that causes a living target to move back along the chain of evolution, causing it to become its own ancestor. For example, a human being hit by the ray would become a Cro-Magnon, then a Neanderthal, and so on. If the ray keeps hitting the target for long enough, it will become a pool of primordial slime.
* DisciplinesOfMagic:
** ''GURPS Fantasy'' gives options like Craft Magic, Master of the Trade, Oaths, and True Faith.
** ''GURPS Magic'' has the option of Alchemy.
** ''GURPS Powers'' has Psionic Magic.
** ''GURPS Wizards'' promoted itself as having 28 different types of Wizards, althro only a third of them would normally be considered wizards in other game systems.
* DivingSave: Possible by combining dodge and drop with sacrificial dodge. If the dodge is good enough the rescuer can escape harm too.
* DodgeTheBullet: Sort of. You can use the Dodge defense against bullets but it doesn't strictly represent dodging. Most moving things get a Dodge stats to represent that fact that they're not perfectly predictable.
* DontSneakUpOnMeLikeThat: The "Berserk" disadvantage, in addition to everything else the disadvantage entails (rabidly attacking every enemy on hand with whatever weapon is on hand), also conveys this, treating anyone trying to restrain the character, friend or enemy, as an enemy. Earlier editions nicknamed the berserker rage "the Doom of the North" for this very reason.
%%* DuelingHackers: ''GURPS'' rules for deckers show up in a ''Pyramid'' article on {{cyberpunk}}.
* DyingRace: In 3e there was actually a disadvantage called "Dying Race". It didn't really affect gameplay and was mostly for flavor, so it was turned into a subset of Social Stigma in the next edition.
* EarlyInstallmentWeirdness: The 1st and 2nd editions didn't quite live up to the "Universal" in the title, being heavily oriented towards a low fantasy setting like its spiritual precursor ''TabletopGame/TheFantasyTrip'', with only rudimentary firearms rules, and magic spells, psionics, and superpowers in separate supplements. This improved in the 3rd Edition, especially after the release of the first ''Compendium'', and the system finally became truly integrated in the 4th Edition.
* EatsBabies: Restricted Diet (Occasional) might restrict your diet to any of "Virgin's blood, rocket fuel, [[BreadEggsMilkSquick babies]], radioactives."
* EldritchAbomination:
** The third edition version of ''GURPS Fantasy'' treats the Babylonian primordial entity Tiamat this way, giving stats for a minor avatar of her that, while not appearing particularly odd (it's an enormous dragon with four eyes), can still cause terror from just looking at it. Said avatar automatically regenerates every year, making the effort of trying to kill it futile. To get rid of it permanently, you'd have to track down and kill the real Tiamat... who is half the size of the universe (about 2.24* 10^18 HitPoints), so good luck with that. There's even a Lovecraft quote after the stat block.
** The game has more in different settings and splatbooks: for example, ''GURPS Cabal'', with its cosmology based on the qabbalah's Sephirot, has the creatures of Qlipoth and its Ur-Lords; ''Creatures of the Night'' has the godlike Betweeners, the force called "[[DarkIsEvil the darksome]]", which is responsible for the creation of the literal organ-farmer [[SplitPersonality Darklings]], and many of the non-undead creatures described; a few licenced settings (like ''Cthulhupunk'' and ''Literature/TheWarAgainstTheChtorr'') have their own native abominations; and ''Infinite Worlds'', the meta-setting that ties TheMultiverse together, not only makes ''all'' the previous settings inter-accessible, but also has at least one world (Taft-7) where humanity never evolved in the first place because of Great Old One (or similar) influence 50 million years back - and although they're long gone, they left enough "Fun Stuff" behind (and the risk of attracting their attention is great enough) for the agencies overseeing interdimensional travel to quarantine the world from any travel there whatever the reason.
** ''GURPS'' newsletter ''Roleplayer'' #10 (May 1988), adventure "The Isle of Night". T'Soquat is a minor Thing That Man Was Not Meant To Know. It resembles a giant lobster with pale gray-green skin and [[RedEyesTakeWarning glowing red eyes]]. It has an acidic secretion SuperSpit, SuperStrength and large PowerPincers, and each HumanSacrifice it receives improves its defenses against being harmed.
* ElementalPunch: Innate Attacks, when limited to touch range, give a character this power. ''Power Ups 1: Imbuements'' takes this a step further, letting you augment your attacks. For instance, [[PinballProjectile your bullets ricochet off a wall]], [[MundaneUtility your camera takes pictures on its own]], and yes, you can make your punches elemental.
* EmpathicWeapon: You can even play them if you want to.
* EveryoneHasStandards: In ''GURPS Black Ops'', the Company's willing to [[IDidWhatIHadToDo do a lot of dirty stuff]] to protect humanity and TheMasquerade. But killing a police officer is completely out of bounds; an op who does that should count his lucky stars if he's ''only'' assigned to nuclear reactor maintenance and monster cage cleaning for the rest of his life.
* EvilIsDeathlyCold: The YukiOnna (a form of TheFairFolk) presented in ''[[MonsterOfTheWeek GURPS MonsterHunters]]'' are not above freezing entire towns [[ItAmusedMe because they're bored]].
* ExactlyWhatItSaysOnTheTin: This roleplaying system is generic. Its core rules are universally applicable.
* ExtremeDoormat:
** The "Slave Mentality" disadvantage turns your character into this. For this reason, it tends to be only used on NPC slaves, some AI, zombies, golems and the like.
** There is also the Minion enhancement to the Allies advantage, which ensures the complete loyalty of the character's allies no matter what.
* ExpospeakGag: Extreme [[FanService Sexual]] [[GagPenis Dimorphism]].
* FaintInShock: The game has a “Fright Check” system to represent the effect on people of overwhelmingly horrible experiences, and some of the results on the Fright Check Table do involve fainting dead away. The third edition supplement ''GURPS Screampunk'' and the fourth edition update supplement ''GURPS Steampunk 1'' augment this with a secondary system of fright checks in response to horrifying revelations of social inappropriateness, to suit the 19th century, Victorian milieu that both cover. Both note that actual period fiction might make the sexist assumption that only ladies will faint away in shock, but modern games don’t have to follow this.
* TheFairFolk: Covered in ''GURPS Faerie'', among other places.
* FantasticLegalWeirdness: ''Pyramid 3/93'' has an article on how superhuman powers might fit in with the law. For example, ''"Extrasensory perception of any kind violates so many privacy laws that it could set back most courts for'' decades."
* FearlessUndead: The default undead templates always include Unfazeable.
* FeatheredDragons: The ''GURPS Fantasy Bestiary'' includes aitvaras in its dragon section, depicted as dragons with the heads and wings of roosters.
* FictionAsCoverUp: ''GURPS Illuminati'' suggests that the Conspiracy encourages the Magazine/WeeklyWorldNews and similar publications to write up stories about conspiracy so that the Serious Press won't believe them.
* FlavorText: ''GURPS'' featured the odd bit of flavor text from early on, but Fourth Edition supplements have made a habit of it, with half-page snippets of relevant fiction at the top of most chapters.
* FlechetteStorm: The "Storm Shuriken" becomes this when thrown. Other rapid-fire flechette weapons also appear in supplements.
* FlexibilityEqualsSexAbility: Having the Flexibility advantage gives you a [[MinmaxersDelight better bonus to the Erotic Art skill than simply leveling it up as normal]].
* FreezeRay: A device of the alien Greys, found in the 3rd edition supplement ''Warehouse 23''.
* FriendToAllLivingThings: Having the Animal Empathy advantage gives this quality.
* FunWithAcronyms:
** The '''B'''asic '''A'''bstract '''D'''ifficulty from ''Action''.
** ''GURPS'' itself originally stood for "The '''G'''reat '''U'''nnamed '''R'''ole '''P'''laying '''S'''ystem".
* GadgeteerGenius: The "[[ExactlyWhatItSaysOnTheTin Gadgeteer]]" advantage makes your character into one. By extension, the "[[MacGyvering Quick Gadgeteer]]" advantage lets you do the same, but with less time and resources.
* GenericistGovernment: Government regulations are represented by Control Ratings. If the CR is greater than the Legality Class of an item or action, you roll a die against the difference between the CR and the LC to decide if it's legal.
* GeneticEngineeringIsTheNewNuke: The 4th edition has one volume, ''TabletopGame/GURPSUltraTech'', dedicated to mechanical and electronic SF and futuristic technology -- and another volume of comparable size, ''TabletopGame/GURPSBioTech'', dedicated to biotechnology, medicine, and genetic engineering. While, in keeping with the system's realism-based model, most of the products of genetic engineering described there are relatively low key, there are some radically advanced options, such as biological spaceships and "proteus viruses" that completely transform living things.
* GenreBusting: Most volumes come with tips on how to use other volumes with them.
* HackAndSlash: The ''Dungeon Fantasy'' book is for when you want to roll back GURPS to the days where adventurers looted tombs for no reason other than random treasure. It's notable for [[ShownTheirWork showing their work]] as much as they do anywhere else, and explicitly banning any abilities (such as teleportation or great wealth) that work against dungeon-crawling.
* HandCannon: ''GURPS'' offers various big guns across the different genres and settings its supplements cover. For example:
** The magnum pistol from ''TabletopGame/GURPSUltraTech'' fires a 15mm round, larger than the bullets in a modern anti-materiel rifle. And then there's the shotgun pistol...
** ''{{Steampunk}}'' genre and setting books feature handguns comparable to the largest real-world magnums and slightly larger. This fits; whereas modern firearms have, if anything, tended to use smaller bullets, because they can fit more in a magazine and fire them with higher muzzle velocities, and a slightly smaller, faster bullet will usually do enough damage to take an opponent down, the Steam Age had something of a bigger-is-better approach to weapons design, by comparison.
* HardCodedHostility: In ''GURPS [[Literature/TheWarAgainstTheChtorr War Against The Chtorr]]'', as in the novels it's based on, there is no way to communicate or negotiate with the alien ecosystem and giant man-eating worms invading and un-terraforming Earth. It's either kill, or be eaten.
* HearingVoices: Phantom Voices allows for various types and degrees of this problem.
* HeroicAmbidexterity: Ambidexterity is a 5-point advantage which allows you to DualWield weapons more effectively (among other obvious benefits). Gaining this benefit for just one skill is a 1-point {{perk}}.
* HeWhoFightsMonsters: See the line of PDF supplements entitled, yes, ''Monster Hunters''.
* HistoricalDomainCharacter: Some of the sourcebooks give stats for such people:
** ''GURPS Arabian Nights,'' for example, stats up Salah ad-Din (AKA Saladin).
** ''GURPS Who's Who 1'' and ''2'' are all about this trope.
* HistoricalFantasy: Many of the historical sourcebooks include period folklore to allow a HistoricalFantasy setting.
* HollywoodHacking: The Computer Hacking skill. The description notes a bunch of other skills that you'd want to use to hack a ''realistic'' computer.
* {{Homing Projectile}}s: Can be bought as equipment, [[SlidingScaleOfRobotIntelligence stat’ed as characters]], or be a function [[TheMagicTouch magically imbued]] into otherwise normal gear.
* HopelessWithTech: Uselessness with technology is the effective result of the “Low TL” disadvantage, which actually represents unfamiliarity with a setting’s general level of tech (so one could be perfectly competent with seriously out-of-date gear). It’s also possible to take “Incompetence” quirks indicating ineptitude with specific technological skills.
* HornAttack: Combat-useful horns are one thing that can be represented by the Striker advantage. And, just as one example among many, the Fetch in ''GURPS Myth'' can butt with their horns.
* HumanSacrifice: A thing that comes up in adventure stories. For example, in the ''GURPS'' newsletter ''Roleplayer'' #10 (May 1988), in the adventure "The Isle of Night", Colonel Fitzhugh has been possessed by the spirit of the Wizard-Chief of the island natives. He tries to summon the EldritchAbomination T'Soquat into our world and sacrifice his daughter Alicia to it.
* HumongousMecha: See ''GURPS Mecha'', ''TabletopGame/GURPSUltraTech'', etc.
* HurricaneOfPuns: ''Dungeon Fantasy Monsters 2: [[BlobMonster Icky Goo]]''
* HyperspaceMallet: ''GURPS Mecha'', which covers quite a bit of {{anime}} material (because that's where a lot of {{mecha}} appear), has rules for this trope, which it refers to as "{{Shojo}} Mallet".
* ImperialStormtrooperMarksmanshipAcademy: An optional rule is the TropeNamer.
* ImpossibleItemDrop: Parodied in ''GURPS Creatures of the Night'' which includes a completely immobile plant monster that comes complete with a treasure trove full of things that are useful when trying to kill plant monsters. Why? Because it enjoys murdering adventurers and taking their stuff (which it then buries somehow).
* InASingleBound: Here called Super Jump.
* InitialismTitle: The source of the game's name.
* IntrinsicVow: ''GURPS Castle Falkenstein''. If a Faerie uses Enchantment or a Pixie uses Love Charm and asks the victim to do something against their basic beliefs, the victim can resist the effect.
* IslandBase: ''GURPS Illuminati''. One potential location for the Illuminati main base is on a private secret island that has been erased from the world's maps, possibly in the Bermuda Triangle.
* JungleOpera: ''Cliffhangers'' covers the topic.
* KineticWeaponsAreJustBetter: To an extent. In the standard SF weapon lists, beam weapons tend to do less basic damage than comparable projectile weapons. On the other hand beam weapons may be better at bypassing a target's armor. It all rather depends on how a given setting’s technology is set up.
* LawfulStupid:
** The Honesty disadvantage can promote this, though an Honest character can break the law if they make their control roll for the disadvantage, permitting characters with less severe "Honesty".
** Codes of Honor/Conduct can also lead to this type of behavior.
* LeeroyJenkins: As noted in several places here, GURPS begins with a premise of "realism;" i.e. KilledOffForReal is fairly easy, BackFromTheDead, not so much (if at all). Nonetheless, the creators seem to love Leeroying inasmuch as there are so many Disadvantages that can produce it (or perhaps they just know that some players will want these options):
** ''Berserk'': You must roll to avoid Leeroying any time you take 3 or more hits in one turn, ''or'' under "Other conditions of extreme stress (GM's option)" -- i.e. pretty much in any combat.
** ''Bloodlust'': You must roll to avoid Leeroying any time you have a chance to kill a "legitimate enemy" -- i.e. pretty much in any combat.
** ''Impulsiveness'': You must roll to avoid Leeroying any time the rest of the party are taking too long discussing something -- i.e. pretty much ''before'' any combat.
** ''On the Edge'': You must roll to avoid Leeroying any time you have a chance to deliberately put yourself in mortal danger -- i.e. pretty much in any combat.
** ''Overconfidence'': You must roll to avoid Leeroying any time you feel yourself a match, or more than a match, for your opponent -- i.e. pretty much in any combat.
* LemonyNarrator: In an example in ''GURPS Sorcery'', after a player proposes a particularly twinkish improvised spell...[[note]]The player wanted to create a spell which would only work on the specific wall she was attacking, which wasn't a disadvantage because it was a one-use improvisation anyway[[/note]]
-->The GM brandishes his foam sword menacingly and suggests she reconsiders.
* LikeRealityUnlessNoted
** ''GURPS'' tries to be realistic, and games using the default rules will be fairly gritty. But if you enable the relevant optional rules, and especially if players buy "cinematic" traits, you'll turn the game away from reality and toward the genre of your choice.
** The common term among fans is that ''GURPS'' presents a [[AcceptableBreaksFromReality "gameable abstraction"]], the more realism you insist on the harder it is to actually play the game. Forum posts are nonetheless full of people trying to make things more realistic.
* LoadsAndLoadsOfRules: Most of them are described as "optional" in the books. Hardly anyone really plays the game with ''only'' the mandatory rules, so to get a game started, the game master needs to make a list of the optional rules he wants to use.
* LongList: Most of the character creation "rules" are really menus of traits that characters can have. ''Enormous'' menus. There are over four hundred skills! Of course, only a few of those will be useful for a particular game, so [=GM=]s regularly make their own less-intimidating lists, perhaps in the [[http://www.sjgames.com/gameaids/gurps/sorter/ trait sorter]].
* LuckilyMyShieldWillProtectMe: Shields work quite well. Not only do they allow for blocking attacks, which makes for a less risky parry, but they ''give a bonus to all dodges, blocks, and parries on top of that''.
* MadeOfBologna: Invoked by a powerful Advantage called "No Internal Organs" [[note]]"Injury Tolerance: Homogenous" in later editions[[/note]].This means a character never suffers from complicated medical problems, because their interior becomes uniform undifferentiated tissue.
* MagicAIsMagicA: GURPS magic in all its forms tends to follow systematic rules peculiar to each form. ''Thaumatology'' and its various supplements are essentially a toolkit to build your own magic system.
* MagicByAnyOtherName: GURPS Magic has the option of Alchemy; GURPS Fantasy gives options like Craft Magic, Master of the Trade, Oaths, and True Faith; and GURPS Powers has Psionic Magic.
* MagicFire: Presented in ''GURPS: Magic''. Essential Flames will burn water elementals. A pyromaniac mage has even more fun options, besides the ever-popular [[Memes/DungeonsAndDragons Explosive Fireball]] there is Burning Death which incinerates the target from the inside out - [[BeyondTheImpossible even if they're magically protected from fire]].
* MagicKnight: Being a classless system it is very easy to make character that fits this description.
* {{Magitek}}:
** ''TabletopGame/GURPSTechnomancer'' is about a world where technology blends with magic.
** ''Monster Hunters 5'' has a section on Technomagic. This is the use of computer code to replicate Ritual Path Magic, akin to the premise of the ''Franchise/ShinMegamiTensei'' franchise.
* MamaBear: A sidebar in ''GURPS Bestiary'' makes it very clear why you shouldn't get between a mother animal and her young.
* MarriageBeforeRomance: In ''Social Engineering'', it's possible under certain circumstances (either an ArrangedMarriage, or a marriage of convenience or desperation) for a marriage to begin without romantic ties, and there are mechanics for courting your spouse if you choose to do so.
* MassSuperEmpoweringEvent: Wild Card Day in ''ComicBook/{{Wildcards}}'' brought super powers to the world.
* TheMenInBlack: They appear in several add-on books.
** ''GURPS Illuminati'' has a chapter devoted to them.
** In ''GURPS Horror'', they can get access to the "State" powerset.
** In ''GURPS Monster Hunters'' there are provisions for playing TheMenInBlack.
** ''GURPS Black Ops'' for Third Edition was a whole campaign setting specifically for TheMenInBlack.
** TheMenInBlack is also the name Steve Jackson Games uses for its volunteer game demonstrators (such as at conventions and other gatherings).
* MirrorChemistry: One of the entries on the "something went wrong with our dimension-traveling device" chart in ''GURPS Time Travel''.
* MirrorsReflectEverything: A Sunbolt spell, which creates a laser beam, can be reflected by a mirror. The book expressly notes that a laser would easily melt any mirror that wasn't absolutely perfect, but since it's a spell, the RuleOfSymbolism allows this to work.
* MoeAnthropomorphism: Pyramid #3/97 has rules for this, and a worked example for a Sa'ar 3 missile boat.
* MuggleWithADegreeInMagic: Under the ''default'' Magic system, in a Low or Normal Mana world only characters with the Magery advantage can cast "normal" spells (non mages can cast the Least of Spells in Normal mana). Because the default magical system treats spells as skills like any other, it's entirely possible for characters without Magery to ''learn'' spells, even if they can't cast them. The Thaumatology skill represents a knowledge of the underlying structure of magic, and likewise does not require Magery or spellcasting ability (though Magery gives it a bonus). GURPS Thaumatology has options such as "Limited Non-Mage Ceremonies".
* MultiArmedMultitasking: You can take the "Multiple Arms" advantage, though you then need to buy special coordination to use them for anything other than holding stuff.
* MultiplePersuasionModes: The skills Carousing, Diplomacy, the Enthrallment group (Captivate, Persuade, Suggest, and Sway Emotions) done by fantasy bards, Erotic Art, Fast-Talk, Hypnotism, Leadership, Merchant, Musical Influence (cinematic), and Public Speaking. There's an entire supplement (''Social Engineering'') detailing how these work and including even more (such as Propaganda).
* {{Multishot}}: Appears in ''Imbuements''.
-->"If your skill is high enough to deal with -18, you’re certainly welcome to try for a [[AutomaticCrossbows RoF 20 bowshot]]!"
* MusclesAreMeaningless: Can be played straight or subverted.
* NeckSnap: an option for grappling, requires high strength or some training to pull off.
* NewPowersAsThePlotDemands: Modular Abilities is made for this trope.
* NinjaPirateZombieRobot: Making these characters is what the system specializes in.
* NonHealthDamage: You die if aging causes ''any'' stat to drop to zero. If some other force drops a stat to zero you're rendered all but helpless.
* NonHumanUndead: The Zombie Vehicle spell, which is designed with spaceships in mind.
* NoSenseOfHumor: Available as a disadvantage.
* NoSuchThingAsBadPublicity: {{Invoked}}. On the front of GURPS Cyberpunk, the writers advertised that the game had been seized by the Secret Service, and an interior section mentioned the circumstances (the Secret Service had called it "a handbook for computer crime"). Of course something like this is going to be free advertising.
* NotQuiteFlight: The Flight advantage has a lot of different ways to make it like this; also, telekinesis can be used for locomotion, and there is the Walk On Air advantage.
* NumberOfTheBeast:
** TheMenInBlack in ''Horror'' have a point total of 666.
** In ''Magic'', rolling an 18 on the critical spell failure table (which means rolling three sixes on 3d6) summons a demon or other malign entity.
* OffOnATechnicality: There's a section with a rule for this. When a PC is arrested, the cop making the arrest must (secretly) make a Law (Police) skill roll. On a failure, the PC (or his lawyer) can make a Law (Police) or Law (Criminal) skill roll to find what rule of procedure the cop broke and get the PC released on a technicality. If the cop makes a CriticalFailure, the procedure breach is so blatant that the PC is released without trial. Of course, it would only apply in procedural societies or societies concerned with the human rights of their citizens, so don't hope to pull this off in a [[GenericistGovernment Control Rating 6 government]], where you will instead be subjected to a KangarooCourt.
* OmnidisciplinaryScientist: While realistic games handle the various subdivisions of the sciences by means of an extensive skill list and rules for specialisation, omnidisciplinary scientists appear in more cinematic games by means of the ''Science!'' skill. [[MadScience The exclamation point is key]]. The game’s 4th edition introduced “wildcard” skills in other fields, such as ''Detective!'', ''Gun!'', ''Music!'', and ''Sword!''.
* OneHitKill: A radioactive attack that hits someone for 4000 rads gives them one HT roll to survive, but if they manage a CriticalSuccess... they die slightly differently.
* OnePasswordAttemptEver: In the ''Warehouse 23'' supplement, anyone trying to log on to the Warehouse's computer remotely must input two separate passwords. If the second password is incorrect the computer assumes that an intrusion is taking place and doesn't give the intruder another chance.
* OnlyFleshIsSafe: Spells from the College of Making and Breaking will only affect inanimate objects.
* OurCentaursAreDifferent: Onocentaurs in 3E ''Fantasy Folk''.
* OurDragonsAreDifferent:
** ''GURPS Fantasy Bestiary'' (for 3rd edition) includes a section dedicated specifically to dragons.
*** Firedrakes are the standard Western dragon -- LongLived, four-legged, winged, fire-breathing terrors, intelligent and capable of speech and powerful magic but chiefly concerned with hunting and hoarding treasure. They hatch already the size of an adult man and keep growing throughout their lives. They don't grow weak or senile, [[StrongerWithAge and only become stronger and wiser as they age]]. They're even said to [[TheAgeless never die of old age at all]]. Luckily for other creatures, they're not common -- it takes a lot of prey to keep one fed, and they also experience high mortality rates as hatchlings.
*** Chinese dragons, or ''lungs,'' have features from almost every animal -- except tigers, [[TigerVersusDragon their mortal enemies]] -- plus pearls under their chins and magical growths on their foreheads that allow them to fly. Only the males have horns and whiskers. They are strongly associated with water -- they typically live in deep pools and underwater caves or behind waterfalls -- are adept shapeshifters and their temperament varies depending on whether they lean more towards Yin and Yang: when Yang is dominant, they are preservers and protectors; when Yin is dominant, they are destroyers. Several types of lung exist. Kioh-Lung are the youngest of their kind, have not yet grown horns or back legs and mature into one of the various kinds of adult dragons at 500 years of age. Li Lung are the least magical of these, resemble [[CatlikeDragons dragon-headed lions]] who fly with physical wings, cannot breathe water and can cause earthquakes. Lung Wang resemble giant dragon-headed turtles, and live in the ocean. P'an Lung are slender, serpentine creatures that live in the sky and can control the rain. Shen Lung rule over freshwater, are immune to poison and can make people supernaturally lucky or unlucky. P'an Lung and Shen Lung speak the same language, and can create "water fire" that can only be put out with regular fire.
*** Other types of dragon include [[FeatheredDragons rooster-like]], mace-tailed aitvaras; azhi dahaka, evil, three-headed legless dragons with a different BreathWeapon for each head; the seven-headed, snakelike and maiden-eating herren-surge; the kakutan, which resembles a horse with a dragon's head; [[MixAndMatchCritters snake-headed, eagle-legged and scorpion-tailed]] mushussus; aquatic, fishlike tarasques; worms or wyrms, wingless creatures closely related to firedrakes and able to breathe out clouds of poison gas; and animalistic, stinger-tailed wyverns.
** The 3rd/4th edition ''TabletopGame/GURPSDragons'' is a whole book about handling almost the whole range of dragon tropes in games, complete with example campaign frameworks for many of them. See the book's own page.
* OurDwarvesAreAllTheSame: As a generic system, ''GURPS'' can potentially handle any sort of dwarf -- but its writers have mostly stuck to the established standard.
** Dwarves in ''TabletopGame/GURPSBanestorm'', the main official GURPS fantasy setting, are a race of natural artificers and merchants. Most adults have at least one point worth of [[IconicItem personal "signature gear"]].
** ''GURPS Fantasy'' offers another variant of the same type.
* OurFairiesAreDifferent: Fairies in ''GURPS Fantasy'' are living illusions. Their magic can be as easily destroyed by iron as they are. Of course, due to the modular nature of GURPS, Fairies can be built in countless other ways resembling other examples on this page.
* OurGhoulsAreCreepier: Ghouls in ''GURPS Fantasy'' are a complete race who are [[ParanoiaFuel indistinguishable from normal humans until they try to eat you]]. The only thing they can eat is human flesh; all other foods are dangerous to them.
* OurGnomesAreWeirder: Gnomes in ''GURPS Dungeon Fantasy'' look similar to thin dwarves and are expert craftsmen. Their entry also notes the possible existence of Hell Gnomes.
* OurGoblinsAreDifferent: Several takes on goblins are present in the various books. For example:
** ''GURPS Goblins'' features an entire alternate Earth exactly like ours, circa 1830s, but inhabited only by goblins -- a parody of Regency England. These particular goblins are extremely varied, being shaped by the exact forms of mistreatment they suffer in childhood, but are alike in being base, crude, and vulgar, as well as standing up to cartoon levels of interpersonal violence.
** ''TabletopGame/GURPSBanestorm'' features goblins as short, green humanoids, immigrants from the mostly arid desert world of Gabrook. They are intelligent, civilized and naturally curious, and actually fit well enough into human society. Hobgoblins are their larger, dumber cousins; while a few live among goblins as servants, most remain hunter-gatherers living in small bands in the wilderness.
* OurGryphonsAreDifferent: ''GURPS Fantasy Bestiary'' includes gryphons and hippogriffs, both of which fly through the use of {{Mana}} stored in their feathers.
* OurHippocampsAreDifferent: ''GURPS Fantasy Bestiary'' classifies as "makaras" any creature with the back half of a fish and the front half of a land-dwelling animal. While the term is Indian in origin, the book notes that it can be applied to creatures such as hippocampi, which would be considered horse makaras.
* OurHomunculiAreDifferent: Homunculi in ''GURPS Magic'' must live in bottles because they are so ridiculously vulnerable that they can be killed by ''harsh light''.
* OurHydrasAreDifferent: ''GURPS Fantasy Bestiary'' describes the original Hydra of myth as a unique monster with nine heads and four legs, but notes that [=GMs=] may redefine it as a whole species of creatures with varying numbers of heads. They can attack multiple times per round and cannot be stunned or knocked out, thanks to their multiple heads, and if one is cut off two more grow from the sump and reach full size in a few rounds unless cauterized with flame. The body instantly dies if the heads are all heads are severed, and the heads die quickly if the main body is killed. The text also notes the original myth having one immortal, unkillable head, and leaves dealing with such a thing as an exercise for the players.
* OurMagesAreDifferent: ''GURPS Wizards'' covers pretty much every implementation mentioned in the trope page.
* OurPerytonsAreDifferent: In ''GURPS Fantasy Bestiary'', perytons are winged deer that attack humans on sight, diving on them from the air in attempts to gore them with their antlers and fighting mercilessly and to the death. Because they cast human shadows, and because of their habit of only killing one human each in any given attack and wallowing in the remains, they are thought to be the souls of particularly bloodthirsty humans, and that killing a living human is the only way they can regain their previous forms.
* OurWerewolvesAreDifferent:
** An optional werewolf template is an uncontrollable problem triggered by the full moon. They're very hard to kill but curiously don't have any special level of strength like most werewolves.
** In the ''Banestorm'' setting, people so afflicted turn into actual wolves. It's also not contagious; either you or an ancestor has to have been specifically cursed.
* OurWyvernsAreDifferent: ''TabletopGame/GURPSDragons'' and ''GURPS Fantasy Bestiary'' include four-limbed wyverns as one of the several subtypes of dragons. They have no breath weapons but possess poisonous barbs at the end of their long tails. They are clumsy walkers but frighteningly fast fliers, and thus prefer to attack targets from the air. They're largely animals, although smart ones, and the book notes that all-dragon campaigns might use them as pets or attack dogs for dragon characters; ''GURPS Fantasy Bestiary'' further describes them as dragon-''like'', but as not actually being dragons. Variations include one able to [[SpikeShooter shoot quills]] from its tail.
* PantsPositiveSafety: A perk is the TropeNamer.
* PinballProjectile: It's a bouncing grenade shaped like a Frisbee!
* PlanetaryParasite: Supplement ''Space Bestiary'''
** The alien species known as world worms travel between planets in pods. When a pod lands, the worms pour out and infest the planet, eating their way to the planet's core. By the time they've grown to [[SandWorm full size (several miles long)]], they've done so much damage to the planet that it disintegrates. After mating, the worms split up and release pods, which begin their journey to find a new planet to destroy.
** Invader swarms are made up of thirty ton aliens that land on a planet in numbers of 200-1200. They breed prolifically, doubling their population every month, while eating all of the organic life they can find. When they reach their maximum population (in the trillions), they launch themselves into space and head for the next life-bearing world, leaving behind a dead planet.
* PlotHole: Yes, there's a trait for this: Gizmo allows you to retroactively have always been carrying a small useful item, regardless of how little sense it makes. ''You can still be carrying the item even if you were strip-searched recently.'' Serendipity allows you to get even more arbitrary.
* PointBuildSystem: Leader of the pack in this regard.
* PortalFantasy: A short supplement, ''[[http://www.sjgames.com/gurps/books/portalrealms/ GURPS Fantasy: Portal Realms]]'', covers this topic in detail.
* PowerArmor: Battle suits in the basic set, and Ultra-Tech has a few new flavors.
* PowerPincers: ''GURPS'' newsletter ''Roleplayer'' #10 (May 1988), adventure "The Isle of Night". The EldritchAbomination T'Soquat has large claws that can do 4-14 HitPoints of damage. If the spell to summon it succeeds, the native villagers under its control will transform and their hands will become claws that do 1-6 HitPoints of damage.
* PracticalCurrency: "Bullets" (that is, rifle caliber cartridges) in ''AfterTheEnd'' are both currency and ammunition.
* ProWrestlingEpisode: ''Ring Dream'' as a whole could be considered this.
* ProchronicProduct: There are rules that allow players to invent such creations, if they have enough gadgeteer bonuses and/or an unusual background. Depending on details, the new inventions can be either verge on super-science, or be simply a case of GivingRadioToTheRomans, affecting how hard it is to "invent" them.
* ProtectiveCharm
* PsychicBlockDefense: The Mind Shield advantage and the Mind Block skill.
* PsychicPowers: A whole chapter is dedicated to explaining how to modify advantages and disadvantages to become these, and how to build characters that use them effectively
* RankedByIQ: The game uses "IQ" as the short-form name of the Intelligence stat -- a measure of all forms of intelligence, independent of culture or species -- although it has barely any relation to actual measures of IQ. Apparently it wasn't meant to.
* RapidAging: ''Challenge'' magazine #47 article "The Ultra-Tech File". If it works, the 2 day long Rejuvenation process lowers the character's age. If the process suffers a critical failure, the recipient's age increases by 6-36 years.
* RaygunGothic: ''Tales of the Solar Patrol'' covers Flash Gordon and Buck Rogers-type space exploration, while ''Atomic Horror'' covers the aesthetic of the 1950's B movies, such as radioactive giant insects, flying saucers, man-eating plants and the like.
* ReactionlessDrive: Five different types in the ''Spaceships'' supplement.
* ReallyGetsAround: The Lecherousness disadvantage.
* RecycledInSpace:
** Any setting + ''GURPS Space'' = Any Setting IN SPACE!
** A pastime of some ''GURPS'' aficionados is grabbing three random ''GURPS'' sourcebooks and [[http://www.weirdrealm.com/cgi-bin/webdb/campaign.cgi making a gameworld out of them]].
* RedEyesTakeWarning:
** ''Fantasy Folk''. Minotaurs have the disadvantages Berserk, Bloodlust, Intolerance, and Savage. They're aggressively antisocial and eat other sentient creatures. They also have red eyes.
** ''Franchise/{{Conan|TheBarbarian}}: Moon of Blood''. The swamp devils have eyes as red as coals of living fire, and the chaken (ape men) have flaming red eyes.
** ''GURPS Conan and the Queen of the Black Coast''. The Hell Hyenas are huge hyenas with red GlowingEyes. They have a strong bloodlust, attacking that lives and trying to kill it without pity.
** ''GURPS'' newsletter ''Roleplayer'' #10 (May 1988), adventure "The Isle of Night". The extremely evil EldritchAbomination T'Soquat and its minions have red GlowingEyes.
** In the ''TabletopGame/GURPSSupers'' adventure ''School of Hard Knocks'', the supervillain Denier is nasty, chauvinistic, selfish and abusive. He also has blood-red eyes in his human form.
** ''GURPS Monsters'':
*** The Mothman has attacked and tried to kill human beings and killed many dogs. It has red GlowingEyes.
*** Spring-Heeled Jack is a callous bully who likes to terrify people, attacks women and has killed at least one person. He has fiery red GlowingEyes.
* ReligiousRobot: C-31 became a Buddhist monk.
* RemoteYetVulnerable: 3rd edition supplement ''GURPS Undead''. If a person's soul leaves their body for any reason (such as undergoing a near-death experience), any ghost nearby can try to possess the body with a high chance of succeeding. If the ghost expends enough fatigue and gets really lucky, they can control the possessed body for up to 36 days.
* {{Retcon}}:
** The introduction of sheath rules in the fourth edition explained why swords were so heavy.
** Reality Quakes and Ontoclysms are mentioned as having this effect ''on global reality'' in ''TabletopGame/InfiniteWorlds'' (and are "especially common in words with superhumans").
* RhymingWizardry: One alternate magic system (recommended for more light-hearted games) uses this. In the example scenario, the mage used random animals to rhyme with what he actually ''wanted'', and the GM ruled that he'd summoned them as well.
* RitualMagic: While the "Ritual Magic" variant is a NonindicativeName (it's actually a different way to assign magic costs and allow for more improvised magic), Ritual Path Magic and its precursor Path/Book Magic fit this trope. The basic idea is that you create an effect, then make it happen by casting a ritual in a consecrated space, using [[SympatheticMagic an arcane connection to the subject]], and gathering ambient energy through ritual practices. Ritual Adepts {{downplay|edTrope}} this by being able to get rid of the requirements, but even then, they have to spend a few seconds gathering energy to cast the spell.
* RulesConversions: Even if ''GURPS'' ''doesn't'' have the sourcebook you want, someone has probably made a conversion guide for it.
* RuleOfCool:
** "When in doubt, roll and shout!" Book 2 of the Basic Set includes some guidelines for how to fudge modifiers when the action is too awesome for looking things up in tables.
** The Daredevil advantage gives a bonus to all rolls made in situations where you're taking unnecessary risks - and preserves you from suffering a critical failure - because that makes you cool
** For one point, you can buy a "Schtick," which allows you to define a CharacterTic, and then guarantees that you'll always be able to do that, even when you'd expect it to be impossible: run in high heels across rough terrain at no penalty, for instance, or keep your clothes clean and cool while swimming in the wilderness.
* RunicMagic: Various ''GURPS'' supplements have included rules for rune magic; ''TabletopGame/GURPSThaumatology'' takes the Nordic "Futhark" runes as a working example of an alphabet that can be used with the generalized rules for "symbol magic".
* RunningGag: After many years of waiting, the 4e ''Low-Tech'' supplement gained an extensive mythology due to the number of questions for which the official answer was "It will be in ''Low-Tech''". Not only would it answer all of your questions about GURPS, it would contain the cure for cancer and be hand delivered by Jesus. Then it appeared and the joke went away.
* SandWorm: Supplement ''Space Bestiary'''. The alien species known as world worms travel between planets in pods. When a pod lands, the worms pour out and infest the planet, eating their way to the planet's core. By the time they've grown to full size (several miles long), [[PlanetaryParasite they've done so much damage to the planet that it disintegrates]]. After mating, the worms split up and release pods, which begin their journey to find a new planet to destroy.
* SapientCetaceans: Seen in some settings.
** The TabletopGame/TranshumanSpace setting plays with this, especially in the deep-sea sourcebook ''Under Pressure''. On the one hand there are "Cetanists"; "[[BrainUploading Ghosts]]" and AIs who believe in the intelligence and spirituality of whales and dolphins, and express this by wearing dolphin bioshells (biological bodies that can run an AI or Ghost) and joining a pod. On the other hand, there are actual dolphins; who are certainly bright enough that translator software works, but are also bullies, mildly sociopathic and, in short, wild animals. And on the third hand there are Doolittles and Delphi; dolphins who've been [[UpliftedAnimal uplifted]], but who often have the same "personality disorders" (by human standards) as their wild kin. They also find Cetanists a bit disturbing. And then there's Coak, a Delphi who [[IJustWantToBeNormal wishes he was a normal dolphin]] to the extent that he now runs an [[AnimalWrongsGroup anti-uplift terrorist organisation]].
** There is also the GURPS adaptation of the ''Literature/{{Uplift}}'' setting, wherein "Fins" (Uplifted Dolphins) are a playable species, complete with the tech from the books that lets them operate out of water.
* SapientTank: Shows up in ''Reign Of Steel'' and ''OGRE'', and can be a player character in the right games.
* ScaryScorpions: The Giant Scorpion in the ''TabletopGame/{{GURPS}} Bestiary'', which is two yards long. If its claws and bite don't kill you, its sting definitely will.
* ScrewTheRulesIHaveConnections: ''Social Engineering'' and its sub-books provide a variety of ways to get and employ connections. ''Pulling Rank'' is mostly about employing your official position legitimately (for example, if you're a soldier, you can call for a medivac and the roll determines whether the base has support available), but it can also be used for "inappropriate" requests at a hefty penalty. For example, one possible request is for a cop to get authorization to ''illegally'' apprehend someone and take them to a small room, where nobody will ask [[JackBauerInterrogationTechnique how they got the information that they mysteriously come up with]] - but if you ask for this and you're not doing it to a terrorist or similarly scary bad guy, you'd better have a real good deal with your superior or there'll be hell to pay.
* ScoundrelCode: The game offers a Pirate's Code of Honor in addition to the more standard types. It is, needless to say, less restrictive.
* SeaSerpents:
** ''GURPS Fantasy Bestiary'' describes sea serpents as legendary, solitary predators that will attack anything smaller than a whale. They will attempt to crush smaller targets in their coils, but can just as easily rear up to pluck sailors right from a ship's deck.
** ''TabletopGame/GURPSDragons'' includes sea serpents as the oceanic counterpart of landbound dragons; see the book's own page.
* SenseImpairedMonster: ''Monster Hunters 3: The Enemy'': The [[SewerGator albino sewer-dwelling alligators]] are blind, but can track prey by sound or by the vibrations in the sewage that they make while moving around.
* SerialEscalation: Almost any character from any setting can be made into a player character in ''GURPS'' (with enough points).
* SharpenedToASingleAtom: Superfine blades divide damage resistance by two. Monowire blades divide damage resistance by ten. Nanothorn blades divide damage resistance by ten and ''shred'' the bonds that hold the atoms in molecules together.
* ShoutOut:
** With this many supplements, quite a few authors can be expected to have indulged in shouting out; see the [[ShoutOut/TabletopGames games shout-outs page]]. Examples occur in ''International Super Teams'', ''Steam-Tech'' and ''Illuminati'', just to start with. One notable instance; in ''Fantasy II: the Madlands'' the terrifying EldritchAbomination gods are based off the characters from ''Literature/WinnieThePooh.''
** From GURPS: Fantasy: ''A high fantasy traitor might be motivated by passionate jealousy, tempted by the devil, or perversely sympathetic to the other side; [[Literature/TheBible a low fantasy traitor wants 30 pieces of silver]].''
** The November 2016 issue of ''Pyramid'' includes rules for playing an AnthropomorphicPersonification based on various military hardware, including an Israeli [[VideoGame/KanColle warship]], [[VideoGame/GirlsFrontline a MAC-10 machine pistol,]] and even a [[Anime/StrikeWitches troubled teenage girl with plane parts strapped to her legs.]]
* ShownTheirWork: ''GURPS'' sourcebooks are notorious for how complete they are, in many cases the setting and research in them is used by gamers using other systems because of how well written they tend to be. The third edition ''Bio-Tech'' book, published in 2002, was noted to be as up to date on real world Biotech as some college textbooks on the issue, by a variety of professionals in the field. The TabletopGame/TranshumanSpace supplement ''Deep Beyond'' includes calculations about the conditions on the Galilean moons and Titan from the space scientist who co-wrote the book... and details were in GURPS before they hit print in the academic journals. And in 1997, the ''Camelot'' sourcebook actually ended up on the recommended reading list for a course in Arthurian Literature at Indiana University.
* SiliconBasedLife: ''GURPS Space Bestiary'':
** The Fridge is a silicon-based life form that lives in arctic regions and looks like a grey rock up to three feet high. It kills other creatures by lowering the temperature nearby, doing 1-6 HitPoints of damage per second.
** The Volcano Beast is an arctic silicon-based predator that hunts by generating a burst of intense heat that roasts nearby animals. It takes the form of a dark grey cone 4 yards tall.
** The Warmer is an arctic silicon-based life form that looks like an amorphous grey rock a yard wide. It generates heat to melt through snow so it can eat the vegetation underneath.
** The Mine is a silicon-based creature that looks like a three yard wide pink rock and weighs one ton. It lives underground and kills its prey by detonating an explosive gas.
** The Skylens are predators that are transparent, silicon disks about three feet in diameter, attacking their targets with sun rays. They locomote by psychokinesis.
* SlidingScaleOfTurnRealism: Second by Second. But using ''Action'' it's Turn by Turn and using ''Spaceships'' or ''Mass Combat'' it's Round by Round.
* SmartAnimalInconvenientInstincts: The system offers the character disadvantage "Stress Atavism", which is pretty much purely for {{uplifted animal}}s, and specifically models a tendency to revert to pre-sapient behaviors when under stress.
* SocialEngineering: ''GURPS Social Engineering'' is a supplement full of various mechanics for getting people to do what you want in a number of contexts.
* {{Sourcebook}}: '''[[http://www.sjgames.com/gurps/books/ Two hundred sourcebooks!]]'''
* SpaceFighter: ''GURPS Spaceships'' has a supplement that covers fighters. The samples culminate in the Mirage Star Fighter which is so loaded with super science it might as well be MadeOfPhlebotinum.
* SpareAMessenger: ''TabletopGame/{{GURPS}} Fantasy'' supplement ''Harkwood''. The part of Caithness named Blythe was once raided by a band of two dozen lizard men from the desert. The Blythe militia trapped the band and killed almost all of them, deliberately letting three of them escape to let the other lizard men know of their defeat. Since that day, the lizard men have not attacked Blythe.
* TheSparkOfGenius: Appears in ''I.O.U.'' and ''TabletopGame/GURPSSupers''. And the ''Webcomic/GirlGenius'' setting book of course.
* SpellCrafting: The game offers several varieties of magic that work this way, with differing rules about creating spells. Notable forms include Ritual Path Magic, which assigns various types of effects to Paths of magic each of which is bought as a skill, and Syntactic Magic, where Nouns and Verbs are magical skills, and spells are built out of combinations of them.
* SquareCubeLaw:
** Actually taken into account when making characters, larger characters can purchase Strength more cheaply, but have a higher minimum, and with the higher Strength a character gets a higher mass, the weight and size tables also support this data.
** The Growth advantage uses what could be called the square/square law: strength measured in weight you can lift only needs to scale with the square of height. Probably falls under AcceptableBreaksFromReality, since Growth already blatantly violates conservation of mass/energy.
* SquishyWizard: generally averted, but can be played straight, as characters with lots of exotic supernatural powers rarely have a use for Strength (which is tied to HP), and may prefer to put their points much more into magic -- but it is not a core aspect of the system.
* StockNessMonster: The 3rd edition supplement ''Places of Mystery'' has a brief entry on Loch Ness (one of the few non-man-made locations in the book) which points out the problems with attempting a "realistic" treatment of the monster (it would probably have to be a large sturgeon), but notes that a supernatural monster might have been the result of some typically dubious behavior by Creator/AleisterCrowley.
* SubsystemDamage: Not by default, but if you want to use hit locations, they can either have their own allotment of HitPoints, or only risk being crippled by {{Critical Hit}}s.
* SufferTheSlings: They're actually quite powerful low-tech weapons.
* SummoningRitual: Being a properly generic ruleset, ''GURPS'' has more than one magic system that encompasses fancy ritualistic summonings.
* SuperGullible: The Gullibility disadvantage gives this trait to a character. They'll believe anything they're told, no matter how ridiculous it is.
* SuperNaturalMartialArts: The "Trained by a Master" advantage allows characters to buy several exotic skills and chi-based powers.
* SuperReflexes: the Advantage called Enhanced Time Sense.
* SuperRegistrationAct:
** An article in ''Pyramid'' included a section on classifying superpowers by Legality Class - healing powers might require the equivalent of a medical license, having the ability to see in the dark won't raise an eyebrow unless all supers have to be registered, and any but a very free government would at least consider putting a PersonOfMassDestruction in permanent solitary confinement to keep them from nuking everything.
** ''Supers'' briefly touches on this, but it doesn't get much play - but some repressive governments might want all superpowers registered.
* SuperSpit:
** Newsletter ''Roleplayer'' #10 (May 1988), adventure "The Isle of Night": The EldritchAbomination T'Soquat can spit an acidic secretion doing 1-11 HitPoints of damage.
** ''GURPS Space Bestiary'':
*** The Marksman Fish can spit a powerful nerve toxin up to twenty five feet out of water. It uses the spit against small birds, causing them to fall into the water so they can be eaten.
*** The Spitting River Snake can spray a strong narcotic venom up to 6 feet away through the air. It uses the spray to render small animals and birds helpless, then eats them. When used against humans, the venom penalizes dexterity and intelligence but does not cause paralysis.
* SuperStrength:
** The game lets you buy Lifting or Striking strength separate from normal strength. To simulate people like Superman or the Hulk the Super Effort enhancement increases normal strength exponentially when you really need it.
** ''GURPS'' newsletter ''Roleplayer'' #10 (May 1988), adventure "The Isle of Night". The EldritchAbomination T'Soquat has a strength of 300, which is fantastically high by the game's standards. When it hits it does approximately 30-180 HitPoints of damage.
* SwallowedWhole: ''TabletopGame/{{GURPS}} Space Bestiary''
** The River Snake is a water serpent that grows up to sixty feet long. It can swallow a human-sized creature whole. While inside the snake, creatures take one HitPoint of damage per second from digestive juices.
** The vortex is a barrel-like aquatic creature about thirty feet tall. It sucks in several tons of water and living creatures. Any living thing inside of it takes 1-6 HitPoints of acid damage per second from its digestive liquids.
* TakingTheBullet: Dodges can be applied to protect others.
* TalentVsTraining: The character competence in skills is a combination of skill level and its governing attribute -- training and talent, respectively. A sword skill of 17 might derive from a dexterity score of 10 with a skill level of +7, or dexterity of 17 and skill level of +0: both would come down to an equal level of MasterSwordsman, but the amount of practice is sometimes important, such as if another attribute is used -- supposing the less talented swordsman had a higher intelligence, he could employ his skill far more effectively in maintenance or feint, than his less trained rival.
* TechnicalPacifist: The Pacifism (Cannot Kill) disadvantage.
* TechnologyLevels:
** Used by name. Every skill that relies on tools has an associated Tech Level. If you try to use that skill with tools of a different Tech Level, you'll get a penalty in proportion to the difference. The rules acknowledge that the TL ratings are arbitrary, and technological progress isn't really linear, so the GM can assign different [=TLs=] to different parts of a society, and for some skills, he's advised to let characters quickly learn how to use individual items of an unfamiliar TL without putting points into it.
** ''Variant'' tech levels happen when you break out of this trope a bit. The (x+y) pattern means that the baseline technology is ''x'', ''but'' you've got a variant technology (SteamPunk, BioPunk, what have you) that pushes the effective TL up ''y'' levels. ^ appended to a tech level means superscience; something that expressly breaks the laws of physics as we understand them and moves the game into soft science. And there's also "advanced" or "retarded" in a particular science - for example, Medieval Europe was mostly TL3, but outside of the Salerno School, was at best TL2 in medicine.
%%* TechnologyPorn: The various * -Tech books include quite a lot.
* TheLastOfTheseIsNotLikeTheOthers: ''Realm Management'''s descriptions of conformity ratings gives three examples for Rating 6: A HiveMind, TheEvilsOfFreeWill, and ''Franchise/TheSmurfs''.
* TheMultiverse: Most obviously, in ''Infinite Worlds''. But if that doesn't suit you, a variety of other planar cosmologies are available.
* ThouShaltNotKill:
** Pacifism's "Cannot Kill" variant plays this completely straight: no killing.
** Inverted with Bloodlust. This disadvantage means that in serious combat, you will attempt to kill all enemies and show no quarter.
* TimeTravel:
** The basic set includes it as the Jumper (Time) advantage.
** The GURPS ''Time Travel'' supplement and its 4th edition counterpart, ''GURPS Infinite Worlds'', explore this topic in depth.
* TokenEvilTeammate: Among the sample characters given in GURPS 4th Edition, Baron Janos Telkozep seems to be one. He's a vampire who's backstory is that he's working for the good guys for purely selfish reasons, and close inspection of his character sheet suggests he's ''not'' a FriendlyNeighborhoodVampire but rather a murderous, greedy bastard. Oh, and he's named after a god with two faces.
* TortureAlwaysWorks: [[DownplayedTrope Not "always,"]] but it gives a seriously high bonus to Interrogation.
* TrainingTheGiftOfMagic: This trope is represented in the default magic system by the fact that Magery (basic Magical Aptitude) is an advantage, and each spell is then learned as a skill. (Variant systems may feature skills that each allow casting of an assortment of spells.) In settings with low or normal "mana levels", Magery is required to work magic outside of the Least of Spells; in high mana areas, anyone can do so, although Magery may give a bonus.
* {{Troperiffic}}: The myriad of the settings + the "cinematic rules" = near-overdose levels of various tropes. Particularly when ''Action'' sub-group of books (dedicated directly to things from action movies and over-the-top fiction) are used, as they enforce tropes as game rules.
* JustForFun/TVTropesWillRuinYourLife: One Pyramid article says that one either needs multiple hours or rather strong resolve to browse the site.
* {{Unicorn}}: ''GURPS Fantasy Bestiary'' describes a number of unicorn types.
** The poh is an equine with a black tail, feline paws and a twisting, coiling horn in its forehead. Unlike horses or true unicorns, it's a fierce predator that hunts tigers and leopards -- and will go after people if no better food is around.
** The fantasy unicorn found in modern fiction resembles a white horse with a long mane and tai, tufts of hair around its hooves, and a long spiraling horn. They're intelligent creatures that can understand human language -- rumor says they may also speak -- and are fierce foes of evil. They can cast a number of spells, mostly focused on healing, purifying food and water, and neutralizing poison, but must touch their target with their horn to do so; they fight mostly by goring with their horns. They're rare and solitary beings who live in deep forests away from civilization, but may ally with very good-hearted people; even then, they only allow themselves to be ridden by children and female virgins.
** The medieval unicorn, discussed separately, resembles a small horse or large goat, with a goatlike beard and a meter-long horn that is red at its base, white in the middle and red at the tip. They're simply animals and aren't magical -- they cannot speak, understand languages or cast spells, although their horn can neutralize poison and be ground to make aphrodisiacs. They are solitary and very rare, and extremely fierce -- they cannot be tamed, fight to the death when cornered, and are natural enemies of lions and elephants. The only way to subdue one is to present it with a female virgin; the unicorn will then lay its head on her lap and fall asleep, allowing it to be captured.
* UnicornsPreferVirgins: ''GURPS Fantasy Bestiary'' notes that fantasy unicorns may ally with anyone of noble heart, but only allow children and female virgins to ride them. The mythical unicorn is likewise said to have a weakness for female virgins, and that on encountering one it will place its head on her lap and allow itself to be stroked until it falls asleep. Hunters can then capture it while its guard is down. This is the only way to catch them, as unicorns are otherwise extremely fierce beings and will fight to the death rather than be captured.
* UntouchableUntilTagged: Suffering a Major Wound (damage equal to or greater than half of one's maximum HP) and botching the Health roll to stay on one's feet/keep from being stunned can quickly lead to this scenario.
* UrbanFantasy: ''GURPS Monster Hunters'' is a series of books about running a game in the vein of ''Series/BuffyTheVampireSlayer'' or ''Series/{{Supernatural}}''.
* VampiricDraining: The Vampiric Bite and more generic Leech powers.
* ViolationOfCommonSense: While this trope is common to tabletop [=RPGs=] in general, ''GURPS'' takes the extra step of providing an advantage called Common Sense. If the GM makes you take it (and if you're the sort of player who needs it, he really should), he'll roll your IQ when you're about to do something stupid; success means he stops you. This makes it possible to ''fail a Common Sense roll''.
%%* WalkingArmory: The TropeNamer.
* WaterSourceTampering: The ''Illuminati'' module the "Fiendish Fluoridators" as one of its many conspiracies.
* WhenAllYouHaveIsAHammer: The Hidebound disadvantage gives a character this as their guiding philosophy.
* WeWillHavePerfectHealthInTheFuture: Some of the supplements, such as ''TabletopGame/GURPSBioTech'', provide this as an advantage.
* WeWillWearArmorInTheFuture: Armor starts to make a comeback in TL 7 with the discovery of lightweight, bullet-resistant synthetics such as kevlar. In some TL 10+ campaigns armor is vital, while in others weapons are so devastating that dodging or shooting first is far more important.
* WeakenedByTheLight:
** 3rd Edition supplement ''GURPS Undead'':
*** Shadows and vampires take 1-6 HitPoints of damage per minute they spend in sunlight.
*** Wights take 1-6 HitPoints of damage each five minutes they spend in sunlight.
** ''GURPS Monsters'':
*** The La Llorona spirit takes 1-6 HitPoints of damage per minute in sunlight.
*** The Mothman takes 1-6 HitPoints of Fatigue damage per five minutes in sunlight.
* WeirdnessMagnet: The trait's description provides the page quote. Technically a disadvantage, but your mileage will vary. It's counted as a disadvantage because it's inconvenient for the character. ''Cool'', but inconvenient. (With the potential to be downright dangerous sometimes.)
* WhenTheClockStrikesTwelve: ''GURPS'' newsletter ''Roleplayer'' #10 (May 1988), adventure "The Isle of Night". When the {{PC}}s' ship approaches the island time will suddenly start passing at an accelerated rate. After the {{PC}}s land on the island time will stop moving forward at exactly midnight, and stay there until the summoning is completed.
* WizardingSchool: ''GURPS Locations: Worminghall'' is a medieval university with faculties for Alchemy and Magic. It goes into a fair amount of detail about how medieval universities in general work, and how Worminghall's magic curriculum deviates from that.
* UsefulNotes/WorldWarII: a main sourcebook with several different ones on different combatants including [[UsefulNotes/NaziGermany Iron Cross]], [[UsefulNotes/BritsWithBattleships All The King's Men]], [[UsefulNotes/YanksWithTanks Dogfaces]], [[UsefulNotes/FinnsWithFearsomeForests Frozen Hell]], [[UsefulNotes/PolesWithPoleaxes Doomed White Eagle]], [[UsefulNotes/FascistItaly Grim Legions]], and others.
* WritersCannotDoMath: Averted. The editor's original career track was particle physics. 3e's infamous Vehicles books was notoriously complex. In 4e all the difficult math is done beforehand and put in tables. When supplements (and issues of Pyramid) let people peek behind the curtain phrases like "nasty transcendental equations" have been known to show up.
* XRaySparks: Featured in the ''Third Edition'' supplement, ''Myth''. One of the illustrations (on page 98) is an archmage named Rabican using a magical sword to fire a lightning bolt at a Fallen Lord named Shiver. Shiver's skeleton can be seen inside her body when the bolt hits her.
* {{Zeerust}}: When 4th edition was being written, is was the tail end of the Stealth technology being in the vogue. It was seen as the future of warfare and the most high-tech development possible. Thus all the expansions and supplement materials dealing with future (especially ''Ultra-Tech'') are written under the assumption that all wars will be fought with minimal armor and maximum use of stealth. Within the publication life of 4th edition, Stealth was rendered nothing more than extremely expensive and very short-lived fad, with variety of ways to deal with it developed in the meantime, making armor for vehicles far more important than their "invisibility".
