''Silent Storm'' (2003, by {{Creator/Nival}}), known commonly as ''S2'', is a [[TacticalTurnBased turn-based tactical]] simulator set during the [[WorldWarII Second World War]]. The game is played in a 3D environment, and was one of the first Tactical Turn-Based games to feature fully-rotatable 3D graphics. This sort of design allowed for a [[EverythingBreaks fully-destructible environment]], and this was used to great effect with a [[StuffBlowingUp large variety of explosives]].

The story puts the player in the shoes of a crack commando operative working for either the Allies or the Axis. Put in charge of Special Operations-[=SE2=] or Abwehr Section 2 respectively, you must assemble a [[MultinationalTeam small squad of the best operatives available to your faction]]. Together, you work to counter the enemy's intelligence efforts and uncover the double-agents supplying information to them. However, you quickly discover that a third party is behind everything, and that they have infiltrated both the Allies and the Axis. As the plot evolves, you discover that this "third party" is in fact an international terrorist organization called the Thor's Hammer Organization (THO), who are working to develop a super-weapon that would allow them to rule the world after the Allies and Axis have beaten each other to a bloody pulp.

As with many other games of the genre, your commandos [[RPGElements gain levels in various skills]], and each has his own specialty and abilities which can be capitalized upon. There are 6 classes available, the [[ColdSniper Sni]][[FriendlySniper per]], the [[TheBigGuy Soldier]], the [[StuffBlowingUp Grenadier]], the [[TheEngineer Engineer]], the [[TheMedic Medic]] and the [[FragileSpeedster Scout]]. The game features a slew of different WWII weapons, all realistically modeled and are spectacular to fire within the 3D environment. The combination of 3D gameplay with an engrossing character-development system and reasonable plot were enough to ensure excellent reviews. In fact, due partly to the commonly low-quality of Turn-Based Tactics games created in the 2000's, Silent Storm is perhaps that genre's only real commercial success in that period.

It received a expansion pack called ''Silent Storm: Sentinels'' (or ''S3''), which picked up the storyline a year after the end of the war. Thor's Hammer has been beaten back, and with the end of the war, the various organizations involved in fighting a war suffered from staff cutbacks. Some became criminals, taking what they wanted with surplus weaponry and their honed combat skills. Others banded together, creating an agency called the [[TitleDrop Sentinels]], consisting of [[MultinationalTeam elite operatives from both the former Allied and Axis powers]]. Someone appears to be interested in the military legacy of the Third Reich, attempting to obtain blueprints and examples of prototype weaponry. That's where you come in; a veteran of the war, the Sentinels are interested in recruiting you to find out what is really going on. You wake up in the basement of a house in Poland...

Retaining many of the gameplay elements from ''S2'', it also adds several new mechanics, in addition to tweaks to several existing ones. [[BreakableWeapons Weapons now have a durability stat]], and may jam or misfire if it gets low enough. As the Sentinels are not a government-funded organization, its agents have to pay money for their equipment and to hire additional operatives, rather than being issued or assigned to them for free.

An officially sanctioned [[GameMod mod]] was released commercially as ''Hammer & Sickle''. Set in the same universe as ''S2'' and ''S3'', it takes place in 1949 during the ColdWar. Put in the shoes of an undercover Soviet agent in the British-American sector of occupied Germany, the player must unveil a tangled web of intrigue and conspiracy, as well as thwart the machinations of an old enemy. They must tread carefully, however, for their actions may spark WorldWarIII...

Marketed as a Tactical RPG, it completely reworks the game mechanics. Battles are now far more lethal, a weight limit has been implemented and clothing is no longer just cosmetic, to name a few.

----
!!This series contains examples of:
* AllYourBaseAreBelongToUs: Late in ''S3'', the Sentinels' home base comes under full-scale assault by THO forces. The Sentinels have the advantage of heavy weapon emplacements and trenches, but they will lose without your help.
* AntiFrustrationFeatures:
** In ''S3'' and ''H&S'', when you exit a mission area, before reading the score board there is an autoloot tab in which you can manually pick any of the area's item (if you found them, of course) and drop some of those you carried.
** ''S3'' Sentinels' HQ includes a stash in which you can store some items. When you have a special temporary party member in a mission, his inventory is automatically given to the stash when you leave the area.
* ArbitraryHeadcountLimit: Your team can only have up to six characters (the PC and five hirelings). Some missions also give you control of a guest character, who will be placed in an extra seventh slot if your team is already full.
* ArmorIsUseless: Averted.
** [[spoiler: Panzerkleins]] are near impervious to almost any form of weaponry in ''S2'' (including rocket launchers), though this is toned down in ''S3''.
** Body armor in ''S3'' helps a lot against incoming fire, sometimes stopping it completely if its penetration is low enough. However, they only protect certain parts of the body.
* AuthorityEqualsAsskicking: Subverted for the officers, who have more vitality points than the regular troops but are usually armed with pistols instead of heavier weaponry, so they are less accurate and inflict less damage.
* {{BFG}}: The heavy weapons category, including machine guns and rocket launchers.
* BlastOut: One of the main story missions in the Allied campaign is one of these - you're investigating a group of friendly soldiers who are suspected of being Nazi agents, and [[PoorCommunicationKills they all suspect ''you'' of being Nazi agents]]. You're all standing together in a cramped room, and everyone is armed, and one thing leads to another and suddenly everyone is shooting everyone from two feet away.
* BlownAcrossTheRoom: Can be caused by explosives or high powered firearms.
* BoobyTrap: Quite a few chests and doors have a nasty surprise in store for someone who tries to open them. They can be disarmed by an Engineer, who can also plant some of their own. Be careful when disarming, though, as they can blow up in your Engineer's face if they [[CriticalFailure do badly enough]].
* BoomHeadshot: Present in all the games. A hard to hit target, but it causes more damage than shooting the torso, and can inflict some of the nastiest crits in the game. Taken UpToEleven in ''S3'', as headshot kills [[YourHeadAsplode remove the head]].
* BreakableWeapons: Introduced in ''S3''.
* BulletholeDoor: Most firearms can blast their way through a wooden door with ease, though metal doors require explosives to break through them. This method of entry can be ''required'' in some cases, especially if explosives have blown a crucial part of the scenery away (see EverythingBreaks). It's also useful if your engineer isn't skilled enough to pick the lock.
* CarryABigStick: The available melee weapons include a couple of clubs.
* ChoiceOfTwoWeapons: Each team member has two slots which can be filled by absolutely any item (weapon, explosive, or tool), which are the two items that are ready to be used. Switching between them is a free action, but changing one of the items during a fight requires to spend action points.
* ChunkySalsaRule: Explosives can turn the enemy into a [[PinkMist red mist]].
* ConcealmentEqualsCover: Averted. Bullets can still penetrate and hit, depending on the object used as cover. Most rifles and machine guns are even able to shoot through walls.
** This can be abused: use a hidden spotter to locate the enemy, then eliminate them with indirect fire through the walls. The AI won't return fire if it can't see where it's being shot at from.
* CoolGuns: All of the World War II-era guns on the lists, and a few from just after it.
* CoolShades[=/=]EyepatchOfPower[=/=]LennonSpecs[=/=]SpecsOfAwesome[=/=]SunglassesAtNight: Available as "glasses" customization. Each of those features is purely cosmetic and have no effect in-game.
* CosmeticAward: The player characters occasionally gain a medal after a mission. They are displayed in a folder on their character sheet.
* CriticalFailure:
** Failing badly enough while defusing a booby trap causes it to explode.
** Failing badly enough at tossing a grenade[[note]]a regular failure just causes the grenade to land off target[[/note]] causes it land ''right in front'' of its thrower (more HilarityEnsues if the whole group was standing around).
* CriticalHit: These can range from causing the character to bleed, go blind and/or deaf, all the way up to [[ChunkySalsaRule instant death]]. Some of the classes have perks that affect these, whether inflicted on or by the enemy. The Sniper has a very popular perk that always causes critical hits with ''all'' shots from ''any'' ranged weapon, up to and including [[MoreDakka machine guns fired on long burst]].
* DieselPunk: It doesn't start out like this. See UnexpectedGenreChange below.
* EverythingBreaks: Some explosives can take out a large chunk of the environment (floors, walls, roofs), making some areas of the map completely unreachable (the squad is unable to climb straight into a doorway from a hole in the floor). This can sometimes be solved, however, by using even more explosives to create other holes that can be used to navigate between your holes, turning the building into a multi-floor maze.
** In at least one mission, it's quite possible to kill your entire team on the first turn by accidentally blowing out the floor underneath you, sending the entire squad falling to their deaths. You can, of course, [[VideogameCrueltyPotential also do this to the enemy]] on occasion.
* ExplodingBarrels: Explosive barrels appear from time to time. They explose when hit by a bullet, but the blast radius isn't very large. Also, they are usually encountered in areas where they make sense (storage areas, factories, next to an engine-generator, etc).
* FiringOneHanded: Some units fire their pistols like this.
* {{Foreshadowing}}: In a mission, one of the clues is a Russian police report stating that some local citizens spotted in the nearby forest what they described as iron animals (the report emphasizes that they don't drink). Said clue is one of those which unlocks the "Unknown Complex" mission. Depending on the order of which you do the missions, is can be the first area where you have to fight [[spoiler: Panzerkleins]].
* GameBreakingBug: In some versions (including the Steam one), ''S2'' last mission suffers from a bug which ''prevents the FinalBoss to appear''. Fortunately, there is an unofficial patch to fix this issue.
* GameMod: Some can be found [[http://www.strategycore.co.uk/files/silent-storm/mods/ here]] (''S2'') and [[http://www.strategycore.co.uk/files/silent-storm-sentinels/mods/ here]] (''S3''). They actually serve as gameplay modifiers that can be manually enabled and disabled. Among the various available mods:
** No [[spoiler: Panzerklein]] Modification: Very popular mod. It removes the [[spoiler: Panzerkleins and the energy weapons]], replacing the [[spoiler: Panzerkleins]] by regular mooks wielding heavy weapons. It upsets the game's intented difficulty and makes the plot a little nonsensical, though.
** Class Skill Changes: Party members and AI units skills overhaul.
** [=DieHard=]: The game is harder and the AI uses grenades more often.
** Grenade Range Increase: ExactlyWhatItSaysOnTheTin.
** Easier Medical and Engineering Items: Fixes the glitched growth of the medical and technical skills (cf UselessUsefulNonCombatAbilities below).
** [[http://www.strategycore.co.uk/forums/topic/10295-new-s3-mod-all-uniforms-in-development-feedback-is-welcome/ All Uniforms]] (''S3'' only): You can customize you team's appearance by buying them new clothes. It also includes some other features (skills and stats overhaul, grenade's range increased, etc).
* GameplayAllyImmortality: Played straight in the first mission of ''S3'', averted elsewhere. Boris will only be knocked unconscious if his [=VPs=] are depleted, [[http://youtu.be/KP-iKd1cQ2M?t=22m44s even if his head gets blown off]].
* GasMaskMooks: Some of the THO servants.
* GenreShift: ''S2'' starts out as a fairly realistic SpyFiction set during UsefulNotes/WorldWarII where you command a squad of Allied or Axis commandos and tasked with finding traitors and following clues. Then [[spoiler: Panzerkleins]] are introduced, followed by [[spoiler: energy weapons]] and a [[spoiler: shadowy organization straight out of ''Film/JamesBond'' that seeks to get both sides of the war to obliterate each other, so that they can pick up the pieces]]. The change was so jarring, a mod was created shortly after release to remove [[spoiler: Panzerkleins]] from the game (although that makes the plot a little nonsensical).
** ''S3'' takes place a few years after the war, with the game going back to its SpyFiction roots, and the titular organization (made up of some of the commandos from both sides) trying to stop the formerly-defeated organization from going back to its old tricks. Then (sigh) the [[spoiler: Panzerkleins]] are re-introduced (apparently, everyone forgot about them, and none were left in the Sentinels' stocks), and (with TheReveal that [[spoiler:the Sentinels' commander is the head of the villainous organization]]) it goes right back into ''James Bond'' territory with [[spoiler: Panzerkleins]] and [[spoiler: energy weapons]].
** ''Hammer & Sickle'', surprisingly, averts this, as the developers have finally listened to the players and did their best to stick to the SpyFiction genre. This time, since the events take place during the UsefulNotes/ColdWar, the fiction is of this flavor. The PlayerCharacter is a Soviet soldier sent across the Iron Curtain to form a spy network and subvert the Allies without starting WorldWarIII (an actual [[NonStandardGameOver possibility]])... Then the Sentinels and the organization (that just won't die) show up... but without their high-tech toys.
* GratuitousForeignLanguage:
** Each of the characters' lines are filled with words in their own language.
** On each character's file, the rank is written in his[=/=]her own language.
* GridInventory[=/=]InventoryManagementPuzzle: One of the low points in the game. It was slightly rectified in the expansion.
* HitPoints: Called Vitality Points, merely dropping it to zero is a NonLethalKO (for your characters); drop it far enough into the minus (usually by tossing a grenade at someone already out-cold) and the target will die permanently.
** HealingPotion: Averted. Regardless of whether you're in combat or not, [=VPs=] are restored over time and it immobilizes both the healer and the patient until it's done. More specifically, the healer can't do anything else while the patient can turn and shoot normally, but cannot move or change stances.
* HeroicRROD: There are several power-up items (using them requires a minimum level in the medical skill) which greatly increase the vitality points amount for a number of turns, but make the affected character faint when the effect ends.
* HollywoodSilencer: There are several silenced weapons available (there are even silenced sniper rifles which, in the hands of a Sniper with the "[[CriticalHit Always Inflict Ranged Critical]]" perk, are downright deadly). Shooting these while hidden won't automatically reveal your location, though you may still get spotted if an enemy is looking your way. On the other hand, they deal less damage than their regular counterparts and tend to be rather rare.
** The best way to use the silenced rifle (which can only be obtained in one mission) is to hide your sniper and use a hidden scout as a spotter. Even if the enemy is looking your way, they won't spot the shooter, as the shooter is outside their sight range.
* ImproperlyPlacedFirearms: The British and German RedShirts[=/=]{{Mooks}} in ''S2'' tend to wield weapons from the other Allies/Axis-aligned nations in high-level RandomEncounters.
* InfinityPlusOneSword: Several in ''S2'', the [[FrickinLaserBeams Prototype 8M1]], the [[{{BFG}} Sea Devil Scoped]] and the [[KatanasAreJustBetter Katana]].
* InterfaceSpoiler: If you look at the skill trees of your soldiers, you'll see skills like: Enhanced [[spoiler: Panzerklein]] Familiarity. This may lead you to wonder, "What the heck is a [[spoiler: Panzerklein]]?"
* JustAStupidAccent: Most of the characters. Depending on which translated version of the game, it is averted for characters speaking the same language that the dubbed game.
* KatanasAreJustBetter: The Katana is the best (and rarest) melee weapon in ''S2'' and ''S3''. Justified, as the other melee weapons primarily consist of knives.
* KickTheDog: One of the missions in ''S3'' has you visit a Soviet gulag to gather intel. Incidentally, the prisoners rebel against the guards and take up arms. [[DealWithTheDevil You're allied with the guards.]] This is anywhere from distasteful to pointlessly cruel.
* KnifeNut: There are a large array of edged weapons available (mle and throwable), and mle-related skills for your party members, the most mle oriented party members being the scouts and the medics.
** KukrisAreKool: There are kukris knives available.
** MacheteMayhem: ... and machetes, too.
* LevelGrinding: Primarily in ''S3'', and mostly for money rather than improving your characters. You can redo the "random" encounters over and over again to get the enemy's gear, either for actual use or for their monetary value (since sufficient money is relatively hard to come by). In the process, your squad will gain some skill and XP, but there are AntiGrinding mechanisms in place to make sure you can't advance much beyond the optimal level for the next main-story mission.
* LoadBearingBoss: In ''S2'', Orlov in the "Unknown Complex" mission. The mission's objectives requires to capture the enemy officer in charge of the place, along with other clues scattered in the complex. When shot by your team, you heard from a radio he is carrying that his underlings (you are trying to join him, in vain) are about to trigger the complex's autodestruction. If it happens before you left the area, this is an immediate game over, even if you salvage all the clues and no team member could have been hurt by the blast.
* MeleeATrois: In ''S2'', there are missions involving both Axis and Allied troops fighting against each other and THO soldiers, who are hostile to both.
* MoreDakka: Plenty of it. The various submachine guns and machine guns can quickly pump out a lot of bullets, especially if fired on Long Burst, which only ends if the target dies (this one actually requires to benefit from a specific skill), the gun runs out of bullets or the shooter runs out of AP.
* MultipleEndings: ''S3'' has two, depending on which version of the final mission you choose. ''H&S'' takes this UpToEleven.
* NebulousEvilOrganization: Thor's Hammer Organization (THO) plans to fuel a LensmanArmsRace between the Allies and the Axis, watch them destroy one another, and pick up the pieces. How? By [[spoiler:providing PoweredArmor to both sides, while keeping the best PoweredArmor and EnergyWeapons for themselves]].
* NiceHat: The game has a large array of various countries' headgear, with helmets, berets, and caps.
* NoCampaignForTheWicked: Played with. ''S2'' allows you to play as the Axis and the ''H&S'' player character is a Soviet spy. However, ''S2'' remains largely the same regardless of which side you pick, as you wind up primarily battling Thor's Hammer. None of the games allow you to play as THO, the real bad guys in the ''Silent Storm'' universe.
* NoSwastikas: In ''S2'', there are various places (including character's creation if you play the Axis campaign) in which the gaes include a German flag. It isn't the real swastika flag from Nazi Germany but something like [[http://static.tvtropes.org/pmwiki/pub/images/bizarroflag.gif this]].
* NukeEm: If you don't play your cards right in ''H&S'', WorldWarThree starts, and the final cutscene mentions that it only ends with the Americans nuking several major Soviet cities, including Kiev and St. Petersburg. Moscow is only spared because a Soviet pilot performs a HeroicSacrifice and [[RammingAlwaysWorks rams]] the plane carrying the A-bomb.
* NumberedSequel: Played with in a way. The first game is called ''S2'', and there is no ''S1''. The main reason for this is because an abbreviated form of the game's title, ''Silent Storm'', would be ''"[[UnfortunateImplications SS]]"''. Subsequently, the expansion's title, which contained [[AddedAlliterativeAppeal three words beginning with S]], was abbreviated as ''S3'' to preserve the same scheme, despite being neither a sequel nor the third game produced in the series.
* OldSoldier: Some of the characters you can get on your squad, who are usually veterans of the [[UsefulNotes/WorldWarI First World War]] as well.
* OneBulletClips: While the bullets in each clip and magazine are tracked, reloading only takes as many bullets as the gun needs from them and only from one clip until it's exhausted, at which point the following reloads use the next clip until that one is exhausted too, etc..
** This also means that weapons chambered for the same caliber have fully interchangeable magazines: every weapon accepts every magazine holding the proper ammo, regardless if it's a rifle clip, submachine gun box magazine or machine gun drum magazine. However, their maximum ammo capacity is still determined by their original clip, not the one actually loaded into the weapon; the frequency of reloads isn't changed, you merely save inventory space by packing a drum magazine you can reload from several times instead of multiple clips you can use once.
* OneHitPolykill: The realistic damage and penetration modelling means it is entirely possible to kill multiple mooks with a single high-caliber bullet. The only real difficulty is getting them to line up so you can pull it off. Depending on how powerful the bullet is, you can even do this through walls.
* PinballProjectile: While it's almost impossible to plan, bullets will sometimes ricochet off hard surfaces and may even hit a target (not always the one aimed at).
* PoweredArmor: [[spoiler: Panzerkleins]] appear late in the game, which are nearly completely immune to small arms fire. The only way to beat them are with your own [[spoiler: Panzerkleins]] or with EnergyWeapons, which cut right through armor.
** In ''S3'', they're less resistant to small arms, especially at close range, but EnergyWeapons have a much lower penetration stat than before.
* RandomEncounter: While moving your team around on the world map (between the main missions), "encounter warning" areas often pop up randomly in your vicinity and disappear a short while later. You can actually CHOOSE to have an encounter by moving your squad to that area. Some encounters can net you some great equipment (and can be [[LevelGrinding farmed for money]] in ''S3''). Sometimes (by fluke), an encounter zone will appear right underneath your squad as it moves, causing the encounter to trigger immediately like a classic RandomEncounter.
** Some of these encounters are incredibly rare, and tend to have equipment that cannot be obtained any other way. ''S3'' [[UpToEleven takes this further]], with one that allows you to get a free squad member.
* RareGuns: Both the [=FG42=] and the [=STG44=] (mistakenly called the STG-43 in-game). Both become more readily available in the post-war ''S3''.
* ReligiousAndMythologicalThemeNaming: THO high members use Norse gods' name as codenames.
* RevolversAreJustBetter: ZigZagged. The two revolvers of the game are the Nagant 1910 and the Webley Scott, respectively the crappiest pistol and a very powerful one (the Webley inflicts more damages than most of the ''rifles''). Being pistols, they still lack of accuracy and range.
* SaveScumming: Doing this can allow to succeed some especially tricky shots (like shooting someone far from you with a pistol or a submachine gun) or influence the damages inflicted by a successful shot. Or if the enemy AI managed to hit you (and how badly) during its own turn. This can be exploited, as the game allows you to save and reload during the AI turn.
* SceneryGorn:
** You create this. German towns and British villages are initially fine, but the scenery is destructible and even bullets can take some wall chunks. Then you can also use explosives.
** ''S2'' "German Weapon Factory" is a straight example of the trope, being set in a ruined German factory.
* SequelDifficultySpike: ''S3'' compared to ''S2''. You start with the crappy Magant 1910 no matter which class you choose and almost no ammos (''S2'' first mission was a cakewalk, especially with a sniper) then must scrounge whatever you find for the next couple of missions. you unlock the shops after another mission and can hire other party members even later (in ''S2'' both features were enabled immediately after the first mission). You must pay to hire new party members and acquire other gears (''S2'' companions were totally free, its "shop" was a mere quartermaster who let you take anything you wanted until his - quite large and respawnable between missions - stock of items run out). And the game also added BreakableWeapons in the mix.
* ShortRangeLongRangeWeapon: Averted. Weapon ranges are quite realistic - even submachine guns can shoot across the smaller maps, and that's not getting into rifles. Good luck hitting anything at that distance, though (e.g. a submachine gun's accuracy rapidly drops to 2% beyond a short distance away).
* ShoutingShooter: ''Every'' character becomes this if ordered to fire a machine gun from the hip on full auto.
* StatGrinding: Each stat and attribute gains some points at each use (which also gains global experience to the character), then is increased at specific caps. The skills that can be chosen at each level-up include some which increase their growth rate.
* StupidJetpackHitler:
** [[spoiler: This game has gasoline-powered armored exoskeletons with laser weapons (mostly developed in Switzerland, but Germany is shown producing them as well). The FinalBoss in ''S2'' takes the aforementioned exoskeleton and adds a jetpack, making it a partially literal example.]]
** A fully-functioning [[http://en.wikipedia.org/wiki/Focke-Wulf_Fw_Triebfl%C3%BCgel Triebfluegel]] appears in ''S2''.
* ShoutOut: During one extremely rare RandomEncounter in Switzerland, the team finds a crater with a UFO in it. In the vicinity, the [[InfinityPlusOneSword Prototype 8M1 laser rifle]] can be found, the only fully-automatic energy weapon in the game. The rifle looks exactly like the Laser Rifle from ''{{X-COM}}: Enemy Unknown''.
** This has given some fans an idea for an ''X-Com'' mod for ''S2''.
** It could also be a ShoutOut to VideoGame/{{Fallout}}, where a similar random encounter also occurs.
* TimedMission:
** In ''S2'' "German Manor", you must capture a man and find several clues in his manor. When half of his guard are dead, he'll attempt to retreat toward a rocket in his backyard. If he reaches it (after a dozen of turns), the mission isn't technically failed, but you'll miss a clue which leads to a mission in which you can get [[spoiler: Panzerkleins]].
** Also in ''S2'', "Unknown Complex" eventually turns to be one (cf LoadBearingBoss above).
* TrialAndErrorGameplay:
** The "Place Marked on the Map" level of ''S2'' contains just a ruined house with absolutely no enemies in the area, requiring you to find some data stashed in the basement. The room which leads to the basement's stairs is filled with ''tons'' of powerful mines. The mission is unlocked quite early in the campaign and it is very possible to go there before ever encountering traps of any kind. As the technical skill is broken, you'll probably not be able to disarm the mines anyway.
** The "Act of Terrorism" mission in ''S3'' is virtually impossible to complete without several run-throughs. Your men have to be split correctly between two entry points, and carry exactly the right type of weapons to take out several enemies within the space of about two or three turns once they charge through the doors.
* UniqueEnemy: You occasionally meet enemy agents of officers who have their own name instead of "Allies[=/=]Axies Officer" or something similar, while their stats are similar to standard officers. Some of them serve as for the mission objectives who need to be captured. Sometimes, those named unique enemies exist as friendly {{NPC}}s in the opposite campaign.
* UnwinnableByMistake:
** Consequence of EverythingBreaks. Using explosives inside a building can create holes on the floor or destroy a stair, making an area unreachable. Even if it is required to get there. Also, explosions or stray bullets can destroy ''plot clues'' (you know, the things that are supposed to be picked up in order to complete missions and unlock new areas).
** ''S2'' "Unknown Complex" turns to a TimedMission thanks to the LoadBearingBoss Orlov (cf this trope entry above). In the unmodded game, Orlov can't exit the building because [[spoiler: he drives a Panzerklein]]. The No [[spoiler: Panzerklein]] mod makes the mission fit this trope: Orlov is turned to a human boss who'll join his men's counterattack toward your unit's starting position. You'll probably shoot him outside of the complex and won't have enough time to pick the other mission objectives.
* YouAllMeetInACell: ''S3'' begins with the player character and a Sentinels' member breaking out of a basement in which they were emprisoned by THO. Then the player character joins the Sentinels.
* YourHeadAsplode: Any ranged attack to the head (including throwing knives) can potentially cause this in ''S3''.
