Laws of physics and logic need not apply!
Yeah! I'm the shooter guy! Shooter guy!
As long as I've got my wall, I will never die!
This page exists to answer a simple question: to what extent is any given FPS a simulation of real-world combat?
The earliest first person shooter games were, like most games of the era, heavily gameplay-oriented arcade-style games. That said, it did not take long before games with a realism focus entered the market: the timeline of game releases running forward from Wolfenstein 3Dnote in 1992 reaches both Rainbow Sixnote and Half-Lifenote in 1998 and Medal of Honornote in 1999. Needless to say, the FPS market has seen an overflowing of games all over the scale in the years since.
The general trend of examples along the scale should be familiar to FPS gamers:
- On and near the classic end, games are characterized by fast movement, bunny-hopping, dominance of slow-projectile explosive weapons (rockets), large health gauges (or Regenerating Health) to allow for longer duels, nerfing of the accuracy/firepower of direct-fire automatic weapons for gameplay/fun purposes, and fun tricks like rocket jumping. Vehicles will be easy to pilot, able to dodge/strafe, and able to shoot reasonably well while moving. Hyperspace Arsenals are common. Items are placed on the ground very unnaturally, sometimes even spinning in the air. Artificial Stupidity is common for balance purposes. Bosses will be larger-than-life and over-the-top.
- Approaching the realistic end of the scale, slower, fatigue-restricted movement, use of crouching/prone positions to increase accuracy and reduce visibility, dominance of sniper rifles and assault rifles, the need to use scopes or iron sights for long-range shots, recoil having a detrimental effect on accuracy (and discouraging the use of automatic fire), limited health, and bleeding, leading to very short combat and an emphasis on the use of cover. Vehicles often require multiple crew to operate effectively and will be heavily restricted by terrain. These games often have Mooks but No Bosses, and when the latter are present, they usually are either as easy to take down as yourself or vehicles that the bog-standard bullet hose can't scratch, forcing the need for anti-vehicle weapons.
Examples should be sorted alphabetically within the following four categories, which range from the least to most realistic:
- Classic FPS: These games basically run on Rule of Cool and Rule of Fun. Elements of the game might be inspired by reality, but whatever setting details that exist are usually purely aesthetic, justifications for the aforementioned Rule of Cool/Fun gameplay, or simply convenient from a technical standpoint.
- Semi-Classic FPS: These games take place in settings with internal consistency and plausibility, but not with combat particularly resembling Real Life. Rule of Cool and Rule of Fun aspects are still ubiquitous, although justifications of these tend to be more common.
- Semi-Simulationist FPS: The preponderance of game elements are either based on real equivalents or intelligently extrapolated from present technology. Some Acceptable Breaks from Reality are included, but enough Real Life factors (e.g. fatigue, limited carrying capacity, steadiness of aim) are present to make the player and NPC behavior resemble what would be seen in a situation populated by mortal human beings.
- Simulationist FPS: These games not only employ real-life or intelligently speculated weapons, but make a specific point of simulating major elements of gun battles (e.g. firearm mechanics, bullet physics, physiology of gunshot wounds) in detail. There may be Acceptable Breaks from Reality included, but gameplay not only resembles actual combat, but is radically affected by the modeling of reality programmed into the game. Those that strive for simulationist combat are generally known as Tactical Shooters, and even more extreme examples can be considered Simulation Games.
Needless to say, a game's rank on the scale is not a measure of its quality. Being more realistic or unrealistic does not, in itself, make a game more or less fun; every game offers its own experience, which may be more or less to the liking of a given gamer.
- Alien Arena, as a combination of Quake and Unreal, players move at rather fast speeds, player can carry all the weapons with lots of ammo, there is no regenerating health or weapon reloading.
- Borderlands: Hyperspace Arsenal and teleportation systems that run on Handwavium, low emphasis on cover, and bullets that shoot lightning, acid, fire, and explode, shotguns that shoot rockets in six-round bursts, absurdly effective revolvers that shoot shotgun shells. Rather like TF2 it revels in the ridiculous, and makes no attempt to justify it.
- Borderlands 2 takes it even further than the first game. Guns that explode when you reload, guns that become more accurate as you shoot them, guns that shoot rockets, guns that shoot exploding gyrojet rounds...and that's just among the standard weapon types. There's also a gun that shoots swords that explode into other, also-exploding swords, guns with near-infinite ammo capacity, guns with infinite ammo capacity, guns that shoot balls of acid or ricocheting lightning bolts, grenades that spit acid seeking grenades, grenades that shooting homing vampire missiles that heal the player, MIRV grenades that explode into other, smaller grenades, grenades that bounce around like psychotic rubber balls (and one legendary variant that spits out MIRV grenades everytime it bounces). And this is leaving out the characters, which include a commando who can deploy a massive machinegun turret that shoots missiles and may or may not create a miniature nuclear explosion when it deploys, a mad scientist who creates a giant killer flying deathbot, a berserker who can get so angry that he can rage ammo into his guns and keep his guns from needing to use ammo, and a psycho who gets stronger when he's on fire and can make his enemies explode every time he kills them.
- Blood: A lot like the below Duke Nukem, set a decade after World War 1. Ranks slightly higher, due to supernatural influences on literally everything in the game. Also includes a powerup allowing the player to temporarily go Guns Akimbo with various weapons, up to and including the rocket launcher analogue. Blood II is on equal footing, with much the same gameplay but slightly reducing the Hyperspace Arsenal in return for being able to dual-wield weapons whenever you want to.
- Duke Nukem: Tougher, smarter, more maneuverable monsters than Doom (for the time, of course), and more complex levels. You gotta reload your starting pistol, but you're still trotting around with dual rocket launcher gloves and a shrinking ray. Duke Nukem Forever is slightly higher on this list, being more Halo-like.
- Doom I and II, Wolfenstein 3D — Pre-dating Serious Sam and Quake (obviously). No aiming, no reloading, hyperspace arsenal, basic level design, no falling damage, lots of monsters to blast. The respective sequels are further down, but not by that much.
- The Brutal Doom mod bumps the Doom games up a notch in realism. Enemy AI is slightly more advanced, with some enemies able to roll and dodge your shots (and the Mancubus' flame cannons deal minor splash damage, averting Convection Schmonvection for at least that particular aspect) the new assault rifle and the pump-action shotgun have usable iron sights, your weapons have recoil (and the minigun is often wildly inaccurate because of it,) the BFG 9000 is able to damage the player if they stand too close to the explosion and every weapon but the minigun and BFG 9000 require reloading. Earlier versions also had the player take damage from the ricochet if they shot a firearm point blank at a wall. Of course, the game also got less realistic in a certain other department.
- Doom 3, Quake IV, Return to Castle Wolfenstein — An emphasis on smaller levels with enemies that are fewer in number but tougher and more intelligent. Additionally, the player characters move slower and can take less damage than their classic counterparts and a lot of weapons need to be reloaded. Still, you have a Hyperspace Arsenal and shootouts are still largely run-and-gun, although some use of cover is encouraged.
- Doom (2016) brings the series back to its classic roots, going away from the more horror style theme of the 3rd game, while emphasizing massive firefights in large open arenas, while also borrowing elements from Brutal Doom.
- DUSK: A retraux Genre Throwback to the originators of the Classic FPS. Fast movement, zooming is available but has no effect on accuracy, classic tricks like bunnyhopping are deliberate parts of the game, no falling damage. The only realistic part of the game would be the physics on items like boxes, which exists solely so you can kill enemies by throwing boxes at them.
- GunZ: The Duel: Very difficult to hit things once you hit high levels, due to Game Breakers and "Stop Having Fun" Guys encouraging more Quake-inspired gameplay.
- Hard Reset: No reloading, semi-infinite ammo, no regenerating health (bullet time included when badly injured), regenerating shields... not a lot of jumping, but a lot of hard, explosive, fast-paced Doom-style run and gun action with Serious Sam-style giganto-bosses and weapons that are (mostly) realistic in terms of concept but versatile and definitely not realistic in execution. In the words of Rock Paper Shotgun, it's "a shooter that remembers shooters were meant to kill you".
- Jumping Flash!: It features a rabbit as the protagonist who must collect Muu Muus and can triple jump, so its place this far up the list is to be expected.
- Marathon series: Too primitive for vehicles, good AI, or working cover, but makes an effort with the technology it has. One Bullet Clips are notably averted, and Made of Iron is handwaved with a shield mechanic. No hit-scans, i.e. bullets do not hit instantaneously, but they have a set speed. No falling damage, although this is handwaved as the player being a cyborg. The player's weapon must be aimed up or down to hit things above or below them. Guns Akimbo in effect for some smaller weapons, though in most cases reloading is handled realistically (that is, one gun is put away to reload the other).
- Painkiller: Occupies the same slot as Serious Sam, in terms of More Dakka, over-the-top weapon design with no reloading and no waiting for the weapon swap, level layout, and monsters with simple AI.
- Quake, Quake II and Quake III: Arena: Main character can jump like a grasshopper, or like a flea with explosives. Again, as with Doom I and II, ability to carry a lot of weapons and ammo, no reloading, basic level design, but there are fewer enemies with more complex AI.
- Serious Sam I and II: Practically no reloading (and only for the basic revolvers — which you should not be using past the first levels — and the double shotgun), thousands of incoming monsters with simple AI and very few enemies with hitscan weapons, Hyperspace Arsenal with gatling lasers, very limited falling damage, cannonballism, Time Travel, and ass-whupping.
One of the most popular mods in the series called Parse Error/Serious Insamnity shifts the game further to classic style to the extreme degree. The player moves at the speed of a car, the amount of enemies is tenfolded and weapons are incredibly overpowered to match the amount of enemies. In addition in Serious Sam II variation, most of the weapons are akimbos, including the cannon.
- Serious Sam III: Slightly more down the scale compared to its predecessors with sprinting (although infinite), smarter enemies, and some weapons requiring reloading with two of them (the pistol and assault rifle) having iron sights, requiring them to be super accurate, as opposed to 100% accurate hip firing like the previous games. Not by much down the scale due to sheer number of enemies and retaining other gameplay elements like carrying twenty weapons at once to kill twenty thousand enemies per encounter.
- Team Fortress Classic: Starting with the realistic elements, what few there are: Teamwork heavily encouraged, Short-Range Shotgun is averted (in fact, most guns have pretty realistic spread), grenades, you could only carry around four weapons and eight grenades per class, and you have to reload your shotguns, grenade launchers, and rocket launchers (which also technically averts One Bullet Clips, since these weapons are reloaded one round at a time). Now for the unrealistic elements: Frantic, fast, arcade Quake style gameplay, Bottomless Magazines on plenty of weapons (and strange reloads for the others), Grenade Spam, unrealistically high running speeds, even the most fragile classes can take an unrealistic amount of damage before dying, Rocket Jump, Charged Attack sniper rifles, a Medic who can instantly heal you by hitting you with a medkit, and several "futuristic" weapons like rail pistols and EMP grenades.
- Team Fortress 2: Revels in its over-the-top ridiculousness, just like its predecessor. Once again, realistic elements first: You can only carry three weapons at once (a primary, a sidearm, and a melee weapon), you have to reload most of your sidearms and some primary weapons (like the pistol, grenade launcher, shotgun, rocket launcher, and double barreled shotgun called the Force-A-Nature), the physics engine causes the grenade launchers projectiles to bounce realistically, and cause most guns have reasonable ranges (the shotgun and pistol both are capable medium range weapons), and teamwork is much more encouraged than its predecessor. As for the unrealistic elements: Critical Existence Failure, Made of Iron characters, the cartoonish art style, Bottomless Magazines for a few weapons like the flamethrower and minigun, man portable miniguns, Rocket Jump, sodas that if drank make you temporarily invincible, and much, much more.
Note that cartoony graphics isn't the only thing unrealistic about the visuals, looking at the melee weapons we have a postal box, trophy, and a golf club as just a few of the silly weapons. Also note the fact that there is a shield made out of wood which increases fire resistance. Think about that for a second. If it does damage, you can kill somebody with it. That includes a roll of wrapping paper, the aforementioned wooden shield, your bare fists, someone else's bare fists, an icicle, a dead fish...
- TimeSplitters: aim wobble, no jumping, no health restore during storymode but... as many weapons as you can carry, Dual Wield assault rifles, man portable miniguns, the ability to stick all mines to other players, and split second reload. Though, health and armor restoration and reload glitching was fixed in the third entry.
- Unreal Tournament and sequels: No reloading except for the automag pistol and still focusing on an arcade-like blasting experience. The amount of enemies in the original is fairly low with some having fairly complex AI. However, the game usually encourages to fight in the open. From Unreal Tournament 2003 onwards, double jumps and wall jumps (sometimes combined) were also added, and mutators can be tossed in to make the game even more arcadey.
- Warsow: Gameplay similar to the first 3 Quake games but the game actively encourages bunnyhopping, walljumping and other trick maneuvers. Players move at insane speeds and player can carry many weapons at a time (although the ammo is rather limited compared to some other arena-style shooters) and there is no need to reload them.
- BioShock: A Hyperspace Arsenal, an abundance of healing options, Doom 3-like run-and-gun gunplay, relatively low emphasis on cover, and an assortment of spell-like Plasmid superpowers. On the other hand, the early-mid 20th century era weaponry is somewhat restrained (i.e. the revolver and shotgun have very limited ammo capacity, while the tommy gun is quite inaccurate at range), character movement is relatively slow, and the game does encourage tactical use of your Plasmid powers in combination with your weapons to overcome the more challenging obstacles (the Big Daddies in particular).
- Dark Forces Saga: The first game was quite Doom-like (although with a more coherent plot and mission objectives). Jedi Knight and especially Jedi Outcast are initially much more towards the realistic side, but all that goes out the window once you get your hands on a lightsaber and force powers.
- Fallout 3: Player inventory has a weight limit, though it is generous enough to allow the player to acquire and carry dozens of guns before suffering from Critical Encumbrance Failure. Gimmicky weapons exist (gatling lasers, portable nuke launchers, etc.), but focus is very much on standard firearms. Weapons degrade and jam, but can be repaired by scavenging parts from similar weapons, even if they themselves are nearly unusable. Damage model distinguishes individual body parts, with appropriate effects depending on the part that is affected, though it still takes a lot of firepower to kill the player and it is possible to spam medkits in combat. Player can use awareness-increasing drugs, which help in combat, but they typically have withdrawal effects. Most guns have rather unrealistically wide bullet spread, requiring for most weaponry to be used at closer ranges then would be realistic to not waste ammunition.
- GoldenEye: Player can carry as many weapons as he can find, some of which have infinite ammo. Player can at one point dual-wield a machine gun and a grenade launcher. Player can also drive and fire a Russian tank single-handedly (though this is handwaved in Nintendo Power by mentioning that Bond spent a week at Heavy Armor Training Camp) and using it as a cheat in other levels makes it mansized. However, there is no way to restore health. Putting on suits of body armor will absorb damage until it deteriorates, but that's it.
- Grand Theft Auto V (8th-gen version): The player can carry as many weapons as they want, can wield portable miniguns, and can take quite a bit of punishment before dying. Iron sights are present but are generally optional. However, the use of cover is generally encouraged and enemies generally use realistic tactics.
- Half-Life: Enemy squad tactics ranging from hurling grenades to flush you out to sending in troops one at a time to see if you're dead, taking cover, and such. Taking cover was also encouraged when fighting human enemies and there are no Bottomless Magazines on real world guns. On the other hand, your armor can take several dozen bullets, you can carry a small arsenal of weapons and ammo, you can run at 40 miles per hour while wearing a metal suit and carrying 15 weapons, some guns have unrealistically large magazine sizes (the submachine gun can hold 50 rounds), the grenade launcher under the submachine gun never needs to be reloaded, and most of the cleverer things your enemies do are faked with scripting.
Note that in the Half-life world, the HEV suit has a "Weapons combat suite" as part of the suit, that includes "Defensive weapon selection systems" and "Munition level monitoring." So in terms of One Bullet Clips, it could be very well possible the suit itself manages the ammo and how it's stored for Gordon.
- A spinoff of the famous SMOD of the sequel ranks more realistic on the scale, though still using a Call of Duty-style healing system, or the game's regular med-kits. Newer versions are to include a "bandage" system that forces players to stop and heal.
- Half-Life 2 was moderately more realistic than its predecessor. There is a very realistic physics engine, guns are slightly more accurate across the board, your enemies will do those intelligent things even without scripting, magazines are smaller forcing you to reload more often, cover is more encouraged, there are a few vehicles you can drive, you don't run nearly as fast, and many enemies are more fragile (those who aren't are handwaved as being cyborgs). The handgun also averts Bang, Bang, BANG. One Bullet Clips, Critical Existence Failure, Made of Iron characters, your Hyperspace Arsenal, and unrealistically short weapon ranges (rather similar to Halo or Fallout) are still there, however.
- Halo: You can only carry two weapons, vehicles abound, cover is encouraged, et cetera. On the other hand, you had a regenerating energy shield that could take varying amounts of damage according to difficulty. The first game had a health bar under that shield, while subsequent games removed it entirely (though it makes a return in Gaiden Games which are set before the original or have protagonists who are not the kind of Powered Armor-wearing cyborg the Master Chief is). Also, moving has no effect on accuracy, and shootouts are often much more "run-and-gun" than "peek-and-lean" (especially after Halo 5: Guardians added a bunch of fancy movement abilities), although the regenerating health mechanic does encourage hiding behind cover when injured. Halo: Reach did add reticle bloom, which decreases the accuracy of a weapon if it's being fired too rapidly, but this was pared down in later games. That said, Halo 3: ODST did lean a little more towards realism, with health and lowered accuracy from motion.
- Metroid Prime: Samus Aran is a Powered Armor-wearing walking tank with an impressive vertical leap and an assortment of high-powered energy weapons, facing a series of large, monstrous, alien creatures. Although the emphasis is as much as if not more on exploration than combat.
- Overwatch: On the classic side, healthpacks scattered around the map heal instantly, hero skills such as flight, teleportation, and healing exist, Tank heroes can soak up damage that would be realistically lethal, unrealistic clip sizes (Roadhog's double barrelled shotgun can shoot four rounds)), and Critical Existence Failure causing death only when you run out of health. On the realistic side, heroes carry tend to carry one weapon at a time with a few carrying two and the setting is realistic.
- Perfect Dark: Marginally more realistic than GoldenEye (1997). Hyperspace Arsenal and One Bullet Clips still exist, but reloading is now animated and much slower. Additionally, there is an Energy Shield instead of armor and the ability to crouch with scoped guns for greater accuracy.
- An honorable mention: the additional sniper rifle weapon added to the "A Week in Paradise" mod to Postal 2, which featured a need for the player to lead a moving target. Ballistic features for the sniper rifle alone seen in few, if any, other shooters... and for a game that actually has default controls for urinating (the better to douse flames with), or for yelling "get the fuck down!" Quite a feat.
- Tribes: You can carry only a limited number of weapons (depending on your armor size), grenades, and a single backpack. Teamwork is needed for effective attacks against the enemy base. However, you have jetpacks, plasma cannons, and mortars which fire miniature nukes shaped like fat footballs, you can repair your damage with a infinite-use Repair backpack, and you can shield almost all incoming damage with shield backpacks. In addition, even the slowest classes move at high speeds and the fastest classes can leave even a lot of cars behind so there's even a speedometer in some installments.
- Turok: Although the 2008 Continuity Reboot game is closer to the realistic end, just a little past Doom 3 and Quake IV. However, Turok II: Seeds of Evil features one of the most impressive Hyperspace Arsenals in the genre with 23 different guns, and no falling damage. Also includes things like gatling plasma, weapons that grind out an enemy's brain from within, dinosaurs turned into cyborg monstrosities (such as a giant brachiosaur transformed into a walking artillery/cannon).
- Unreal I: No reloading except for the automag pistol and still focusing on an arcade-like blasting experience. The amount of enemies in the original is fairly low with some having fairly complex AI. However, the game usually encourages to fight in the open.
- The 2013 Shadow Warrior reboot: hold dozens of huge weapons, including a shotgun bigger than your arm, a massive rocket launcher and a severed head, along with a variety of defensive magical skills. The upgrades make your weapons even crazier -turning the shotgun into a four-barreled monster that can fire all chambers at once, dual-wield SMGs, cause nuclear explosions with the rocket launcher and lay mines with a crossbow. However, all weapons must be reloaded, but the magazines are usually pretty big. The 1997 original was made with the Build engine like Duke Nukem 3D, so it fits above.
- Action Quake, The Specialists, Action Half-Life, Action Unreal Tournament mods for those respective games, and now The Opera, use realism much the same way as various action film genres, just enough for dramatic battle.
- Battlefield 1: Though base gunplay is mostly realistic (see Battlefield in Simulationist folder), the depiction of its subject matter has been a subject of controversy due to relying much more on experimental and far less used (but mostly true-to-life) automatic weapons. In addition, there are very powerful Elite Class pickups, but are mostly within the range of expectations for a man with special equipments (and are still mostly inspired by real life). Hardcore exists as usual, and some servers also restrict weapons to restore historical accuracy.
- Battlefield 2142: Although it's rather realistic for the most part for a sci-fi shooter, the vehicles are Humongous Mechas.
- Call of Duty / Modern Warfare: Cover emphasized. Shooting is inaccurate unless you use iron-sights — though when you do use them, accuracy is practically what you'd expect of lasers, allowing you to kill snipers that are less skilled. Shotguns are very short-ranged. However, uses a health system that, depending on your difficulty, takes anywhere from a full magazine to one or two bullets to deplete your health, but regeneration makes you fine and dandy shortly afterward.
- The accuracy for iron sights is somewhat Truth in Television, though gaming logic has turned it into a case of Reality Is Unrealistic. In most modern shooters, 500 yards is sniper territory, but in real life, US Marines are required to qualify at that distance using the iron sights on their M16 assault rifles during basic training. A competent rifleman can easily hit targets at 200-300 yards with iron sights, and 500 yards isn't a stretch either if the target is stationary.
- Call of Duty is all over the scale due to its multiple game modes. While Hardcore multiplayer matches and singleplayer on harder difficulties can be pretty realistic (you can die by taking just 2-3 hits), standard multiplayer can get VERY ridiculous for Rule of Fun. The Perks system is what really makes things unrealistic, as it can let players reload faster than should be humanly possible, sprint indefinitely, and take no damage from falling. Also interesting to note is that, in all game modes, Concealment Equals Cover is averted, thanks to wide-open maps (or, in small maps, very little cover even in rooms - and what cover there is can easily be rushed or penetrated with the right perk or attachment) and the ability for heavier weapons to punch through light walls and the like.
Vanilla mode only requires 3 bullets to kill a person with 100 health (hardcore only gives people 30), providing you're within range of damage drop-off of the weapon and you're hitting the chest or head (which generally apply a respective 1.1x or 1.5x damage modifier, depending on the weapon). Seeing as most rifles do 40-30 or 30-20 damage before the use of perks like "Stopping Power", which also adds a 1.4x modifier, it doesn't take a lot to kill somebody. Unfortunately, poor hit detection and netcode in CoD games, combined with the average person's inability to aim properly leads to a significantly higher amount of bullets used to kill a person.
- Multiplayer can sometimes forget that this is a game about highly trained special forces. Even the most rudimentary of squad tactics and attempt to emulate the basics of real combat usually goes out the window in favor of running around like a blue arsed fly due to random spawning (it was made to be semi-random based on the proximity against a group of opposing enemy, unlike most other team based FPS supposedly to deter spawn campers but as the series goes on it seems to be random) and the series collection of usually small multiplayer maps that seems to get smaller as the series goes on. The series seems geared towards such an approach however, with most modes giving you lightning-fast respawn times without any penalties and most maps being tight and personal, and those ranked high on the leaderboards generally use such tactics. Some later games, like Advanced Warfare and Black Ops III, slide even further towards the classic end with additions like jump-jets, sliding, and wall-running, all while still able to aim and fire your weapons accurately.
- Combat Arms: Really up and down about this. Health does not regenerate, and a small amount of bullets are generally necessary to kill someone, causing people who stand still to get in a lot of trouble. However, running around and out-shooting your enemies usually works. One Bullet Clips are in full effect, though Hyperspace Arsenal is effectively averted by only allowing a main weapon, a sidearm, a melee weapon and extra two extra things for your backpack at most — you aren't even allowed to get more ammo for any gun, all weapons picked up has the exact same ammo as it did when its holder was killed. Armour in the game also is mostly nullified by melee attacks and explosions, aside from one exception — usually like in Real Life. Headshots kill in one hit unless you are wearing a helmet, which only gives you a chance of not being killed in one hit. Moving hurts your accuracy, there is recoil which is exceptionally noticeable with automatic fire, and using a scope is necessary for farther shots — but you are unable to utilize your gun's iron sights if you lack a scope. In execution, the game is generally more run-and-gun on smaller maps with respawning available, and more tactical without said respawning or larger maps.
- This all goes out the window when Specialists show up with Miniguns, Medkits that heal you by walking near them, not to mention the characters themselves being things you'd expect from GI joe.
- Crysis: The same as Far Cry, but with a "nano-suit" to explain the inhuman strength. Also, has quickly regenerating health and an assortment of nanosuit-based superpowers.
- Deus Ex: Player has a limited amount of space to carry all items, including weapons (which are the bulkiest items by far — the inventory system is a forerunner to the briefcase in Resident Evil 4). Weapons are fairly inaccurate unless the player stands still, crouches, or spends points on weapons training. Player must pick up weapons and ammo deliberately by looking at them and clicking, as opposed to simply running over weapons or ammo. All characters take separate damage to individual parts of the body — taking excessive leg damage will slow you to a crawl, taking excessive arm damage will mess up your aim, and taking excessive chest or head damage is fatal. However, health is easily restored by medkits or medical bots, including broken limbs. Also, once you develop your nano-augmented powers sufficiently, you can run as fast as a speeding car and regenerating bullet wounds almost instantly.
- Fallout: New Vegas: Similar to Fallout 3, with a couple of key differences. First of all, the game includes ironsights, weapon mods, much more limited bullet spread, and other small changes that make the game slightly more realistic. Second, New Vegas has an optional "Hardcore" mode (separate from the standard difficulty settings) which drastically increases the game's realism—ammo has weight, healing happens over time instead of instantly, and it's possible to die of fatigue, starvation, or dehydration if you don't carefully monitor your food stocks (though how healthy that food is doesn't matter, you can live on Twinkies and cola) and sleeping schedule. Medkits don't heal all damage; crippled limbs require you to seek out a doctor. Unofficial mods tend to make it harder, such as requiring utensils, or needing a balanced breakfast; Imp's More Complex Needs is a mod that lives up to its name by tracking not only calories (the analogue to the unmodded game's generic "Hunger" stat), but also protein and vitamin/mineral content and forces the player to avoid malnutrition penalties. It also makes it possible to go into a "food coma" from too much eating, makes eating take time and penalizes various skills and stats until it's done to prevent players from trying to scarf down an entire steak during a firefight, and makes it possible to suffer from water poisoning from drinking too fast. It also adds circadian rhythm and forces players to follow their sleep schedule or gradually change it over many days to something else, lest they suffer (more) penalties.
Both hardcore and regular difficulties in the game also include different ammunition types for weapons, like hollow points (which cause more damage but have more trouble penetrating armor due to the bullet squashing on impact) and armor piercing (which penetrates armor very easily but causes less raw damage because of the hard bullet not deforming and making a relatively small hole). The .357 Magnum and .44 Magnum guns can also load .38 Special and .44 Special rounds (like the real life weapons), which deal less damage but cause less wear on the gun. Shotguns can load beanbag rounds that do fatigue damage, allowing you to stun and knock out enemies to avoid killing them or make them easier to Coup de Grāce. Ammo selection is often the most important factor in getting the most out of a gun, and the game even includes reloading benches (something almost unheard of in any video game) where you can break down unused cartridges for powder (divided between pistol/shotgun and rifle, representing faster and slower burning powders), primers (different kinds for different cartridges, with small and large varieties for both pistols and rifles like in real life), and lead and reload spent casings with your preferred load for different combat. Game mods introduce even more realism and options, like various handloading recipes, less-lethal ammo for non-shotguns like plastic bullets, and the ability to break down spent casings into plain brass and reform them into new sizes (something certainly possible in real life) and even rechamber guns into different calibers.
- Far Cry: Player can only carry a limited amount of weapons, but no restrictions on which ones, so this can include machine guns, rocket launchers and high-caliber sniper rifles all at the same time. Heavier weapons do, however, slow movement and increase your stamina consumption when running, but only when actually equipped and held - carrying all three of the above heavy weapons at the same time won't encumber you in the least if you have a machete in your hand. Movement is relatively slow, and movement significantly reduces firing accuracy, encouraging you to fire while crouching or leaning behind cover. Additionally, health and armor pickups are relatively uncommon, and on higher difficulty settings you can only survive a few shots. Combat against human enemies is fairly realistic, with stealth often coming into play, but when you face off against mutants the gameplay becomes much more like a classic shooter. For later games in the series, 2 is slightly more realistic in a few ways (see below), while 3 and beyond are slightly less realistic due to giving the player near-superhuman abilities thanks to the RPG Elements.
- Far Cry 2: A generally strong attempt at portraying a harsh and realistic war, though some elements may feel iffy. Player can carry only four weapons at a time (of those, two are a knife and a pistol, leaving only enough room for 2 rifle-sized or larger weapons). Player must aim with iron sights as there is no on-screen crosshair by default. Your map is a physical item that you have to take out and read to know where you are. Player must use cover effectively to survive. Player must stop and heal serious wounds to avoid bleeding to death (though most of it is Worst Aid, and you can do it endlessly, but at least it tried to depict emergency procedures). Player has freaking malaria. The game also notably has a weapon degradation system, where guns picked up off the ground and in a worse shape can jam, misfire or even completely fail.
On the other hand, syringes (and bottled water) somehow restore health even though most of the damage you take is from bullets, and you can still take a lot of them even without using syringes, and you also have health regeneration for minor injuries. Even with the inventory limit, realism is still iffy. One can conceivably cart around an M79 with 5 grenades, a SAW with 500 rounds, and a sniper rifle with 50 rounds. Plus 5 hand grenades and 5 molotov cocktails. Also, this is the game where almost any damage to a vehicle (collision, fall off a cliff, riddled with bullets, set on fire) can be repaired by opening the hood and tightening the radiator cap, though whether or not this makes the game more or less realistic is a bit of a YMMV.
- F.E.A.R.: Similar to Far Cry, but with incredibly advanced enemy AI and paranormally-induced Bullet Time reflexes. You can carry up to 10 medkits, healing with them is instant, and no matter what, your kung-fu melee attacks are always a One-Hit Kill.
- Fistful of Frags has generally realistic gunplay mechanics, but includes a few less realistic mechanics for fun. All the guns are Wild West era firearms — high damage, low accuracy, and low rate of fire. Most guns can kill in two well-placed hits, and headshots usually mean death. Shooting when running completely ruins your accuracy, fanning your revolver and dual wielding weapons also reduce your accuracy, and dual wielding is treated realistically by having delays in between alternated shots. Picking up more weapons also slow you down. For more fun aspects, you can reload infinitely, respawning is quick and painless, thus encouraging a reckless playstyle, and you heal yourself by making yourself drunk on whiskey.
- Gears of War: Uses Regenerating Health, but includes a cover system that popularized the concept. Characters are also capable of rolling around as much as they want, potentially lengthening firefights, but averts Critical Existence Failure by putting characters into a weakened mode after taking enough damage (if not outright killed). However, characters can take a fair amount of damage before that happens, automatic weaponry usually taking around 3-5 seconds to cause that.
- Killing Floor: No crosshair. Players have a weight limit on their inventory, and bigger weapons slow movement speed when they're held. They also take heavy damage from specimens if they haven't bought armor. On the other hand, friendly fire is off by default, One Bullet Clips abound, weapons are still as perfectly accurate as when aimed when not using ironsights, and the enemies are mutant clones that can survive having their heads blown off and that you get money and random bullet time from.
- Killzone is basically Call of Duty in space. The second game uses a cover system, and thus it is more emphasized than in Call of Duty — and it's quite necessary for survival. The first game was around Halo's level.
- Left 4 Dead: Two weapons only, and one of them is always a pistol or (in the sequel) a melee weapon. Weapons can shoot through walls slightly and can penetrate multiple targets. Has friendly fire on Normal and above, and getting a shotgun blast from a fellow Survivor is an insta-teamkill on Expert. Using medkits for a permanent heal takes a while, during which time the user cannot move or shoot, while pills offer only a temporary boost that slowly runs down. Survivors fire, move and reload slower the more injured they are. An update also made it impossible to continuously melee, as using their guns as clubs gradually wears out the survivors. The mounted minigun has a windup time and can only cover a limited field of fire, but can overheat (ridiculously quickly at that) despite being a minigun. The shotguns reload one shell at a time, requiring the first shell to be chambered before firing after a reload from empty in the first game. No rocket launchers, and grenade launchers only appear in the sequel (and are very rare). On the other hand, pistols serve as an unlimited-ammo Emergency Weapon, and they can be dual-wielded without loss in accuracy. The minigun has unlimited ammunition too. There are stocks of infinitely-usable ammo around. The hunting rifle can be used well without needing the scope, and guns suffer little accuracy penalty when shot on the move. The other guns also use One Bullet Clips. Survivors can take loads of damage on most difficulties except the highest ones, despite not wearing any visible protection. Oh, and there are zombies with numbers of hundreds per level and sometimes even over a thousand.
- Medal of Honor: Like Call of Duty, only (in the first several games) without regenerating health. You could still take a couple dozen SMG hits before dying, although healing items are somewhat common and enemies with automatic weapons and good aim can cut you down pretty quickly on harder difficulties.
- Mirror's Edge: You'll jump and gain momentum pretty realistically and can carry only one weapon at a time (with limited ammunition), which usually have to be discarded to proceed through various obstacles. However, it does have regenerating health, and you can take quite a bit of damage.
- No One Lives Forever: Similar to F.E.A.R. (the enemies even use some of the same animations, the game in fact running on an earlier variation of the engine), only with more primitive A.I., no bullet-time superpowers (or Kung Fu), and much more emphasis on stealth.
- PAYDAY The Heist: Players can only carry 3 weapons at a time. Weapons have to be manually reloaded since they don't reload automatically when the weapon is fully empty. Ammo drops from the cops give paltry amounts of ammo so the player is encouraged to make headshots to save on bullets. Incapacitated players can use their sidearm to defend themselves, but being shot up during this state will completely disable the player. The player can sprint, but they won't be able to shoot or reload while sprinting. Every weapon's sights can be used for better accuracy while shooting, but this will make you move slower. Interacting with tools and ammo/health bags require time to use and the health and ammo bags have a limited volume; this means that it is possible for you to run out of ammo for all your weapons, leaving you with a weak melee attack. Your armor regenerates, but your health is static, so the only way to recover health is to either use a medic bag, level up, or be revived (each revival starts you with lower and lower health) when you go down. Fall damage penetrates your armor and damages your health. The cops are quite smart as they will generally try to flank you from all possible sides and will generally send out multiple special units to end you as quickly as possible. Cops will also let the SWAT Shield go first so his shield can deflect your bullets while they follow behind him for protection. Cops will also use lots and lots of smoke grenades to blind you while they rush in to flank you.
- Soldier of Fortune: Realistic enemy body damage (especially the second game, although damage doesn't slow you down), inaccurate aim when firing automatic weapons (but not when moving), no regenerating health (except Payback), explosions are often fatal, some enemies have armor-piercing bullets and can One-Hit Kill you. On the other hand, health kits and body armor are walk-over pickups, most of the time Body Armor as Hit Points prevails, Critical Existence Failure is in full effect, the crushing majority of aiming is done via a crosshair reticle - there's no aiming down the sights of any weapon that doesn't tote a scope (and there's no aim sway at all when looking and shooting with one that does) -, and despite the different descriptions and flavor text, all grenades save for the flashbangs are Concussion Frags - even the incendiary ones.
- Time Shift: Like Far Cry and Crysis, but with time-bending powers. Unlike FEAR, you have a more complex time-bending system and your time-bending powers are a must to get through the very hectic battles and rather tricky puzzles scattered throughout the levels. Your suit has regenerating shields like Halo, but your health is static and is a whopping one unit of health, which means taking any hit when your shields are out is instant death. Also, no health pickups are present at all in this game.
- Total Overdose uses realistic features only in as far as it supports more dramatic gunfights, then throws in Bullet Time Gun Fu and completely unrealistic special attacks that exploit Rule of Funny and Rule of Cool.
- Urban Terror (a mod for Quake III) is somewhat all over the place. No One Bullet Clips and no automatic reloads. A hard limit on the number of weapons/items/grenades you can equip, so taking a backup SMG might mean missing out on body armor. Injuries may cause you to bleed, which will kill you if you don't take a few seconds to bandage yourself. Damage to your legs will cut your movespeed by a massive amount until treated and any damage will cripple your stamina bar. However allies with a Medkit item can heal you up to 90% health and bandages fix broken legs. Last but not least... wall-hopping, powersliding around corners and even Goomba Stomp-ing enemies are all central elements of gameplay.
- Alliance of Valiant Arms: A game developed by a Korean company named Red Duck, it is essentially Counter-Strike with improvements such as better graphics (via Unreal Engine), 3 classes, passive skills (only helps a little), and 7+ modes. Recoil now shakes the screen up and down and you can now control the recoil better. Aiming down sights is useless on most assault rifles, with 3-4 exceptions (AK107, AK200, MG4KE, etc.), because of the mysteriously slowed rate of fire and increased recoil. The Korean version recently released many overpowered guns that operate like those from Call of Duty, making realism semi-dependent on the weapon you are using.
- As of now, the M1 Garand has been released on the Korean version. For the first time, iron sights are available on a weapon. So logically, if everyone uses M1 Garand, then it'd be further down the list in terms of realism. On the other hand, if everyone uses the SA-58 Para or any other hipfire-only gun, then it'd be further up. As a result, most matches tend to be a hodgepodge of both Counter-Strike and Call of Duty: two completely different gameplay mechanics rolled into one. On top of that, some new guns have the options to select firing modes in-game while others' firing modes have to be selected in the inventory by adding/removing mods. Which gun has what feature depends entirely on its release date. With other WWII guns incorporated in the game since its release including PPSh and STG44, it's truly a monstrous conglomerate that has confused and is still confusing new players and veterans alike with each update including zombie modes, robot modes, and a gameshow mode where you score points in minigames against the opposing team.
- America's Army: Being injured, walking, or holding your gun at the shoulder (rather than aiming by the scope) drastically decreases accuracy. The gun cannot be fired if the player sprints. Being shot twice in the foot puts a player near death, to say nothing of being shot in the torso or head. Health cannot be recovered, and blood loss can only be slowed by lying down, applying a one-time-only bandage, or being treated by a combat medic. Spare ammunition doesn't transfer from magazine to magazine, but each one instead holds exactly how many it holds. Shots can ricochet, but only rarely. Grenades and sniper rifles are king.
- Battlefield series: Fragile humans, war vehicles, squad combat, recoil compensation, suppression effects, destruction effects, and the like. Health regenerates a bit slower than most games (using health packs is recommended), and long-range combat requires you to compensate for travel time and bullet drop. Respawning is painful since the maps are always big and you can only respawn on select points, encouraging players to be careful about their health. However, rockets don't kill humans as easily as bullets, among other things in the name of balancing out multiplayer. Later games in the series straddles the line between Semi-Simulationist and Simulationist (Hardcore is very much on the Simulationist side) due to having many realistic elements but encouraging run-and-gun styled gameplay (earlier games are closer to reality in this regard). The ongoing mod Project Reality (see below) is much more realistic on the scale, Battlefield 1 and Battlefield 2142 is a bit less realistic (see Semi-Simulationist folder) primarily due to the depictions of their subject matter, and Battlefield Heroes is a lot farther up.
- Humans aren't that fragile, even in BF2. Similar to CoD, most weapons have a power in the region of 40-25, which still requires at least 4 or so bullets to kill someone. As with CoD, networking issues usually affects this and increase the number of bullets used by an individual by quite a bit. The only damage modifier in vanilla BF2 is for the head, which allows sniper rifles to only give one-hit-kills on headshots. Explosives don't kill people as easily because the splash damage of handheld explosives is reduced, as said, for the sake of balance. However they are perfectly capable of one-hit-kills, providing the target is hit directly.
- Bad Company 2, at least, throws the whole explosives thing right out the window, with the Carl Gustav rocket launcher being one of the most effective anti-personnel weapons in the game, even moreso if you take the improved explosives perk. Not only is its splash damage sufficient to get kills off indirect hits, but it blows cover to pieces and is fast and accurate. Then there's grenade launchers, which many players believe to be the only truly overpowered weapon in the game. C4 can also be used very effectively if you know what you're doing. Hand grenades are also pretty strong, but you usually can only carry one.
- Brothers in Arms: Places a strong emphasis not only on taking cover, but also on real infantry tactics like suppression fire and flanking maneuvers (which are pretty much essential to win, and the AI uses them as well). Also, weapons are extremely inaccurate without using the iron-sights (and pretty inaccurate with them too). No regeneration or healing, although you can still take a few bullets without dying or feeling any impact on gameplay.
- Brothers In Arms: Hell's Highway has a unique health system that functions much like Call of Duty's, except instead of taking hits, it is more like luck. The longer you lean out of cover or are exposed while getting shot at, the more your screen turns red. Eventually, a single bullet finds its mark and you die/are severely wounded and have to go back to the last checkpoint. It's a system that encourages you to hug cover and not conserve ammo: on the higher difficulties, you won't have a chance to aim much, so snap shots are your friend. Much like they are in real life firefights at close range.
- Call of Cthulhu: Dark Corners of the Earth is surprisingly realistic for a game about fishmen breeding with humans and sea gods. Humans are fairly fragile, and the ones that aren't are handwaved as being half human hybrids. A few bullets will take out any enemy, and the player character and the enemies weren't that far away in health. If anything, they had more health than the player usually. It's also got one of the most realistic body damage systems in video games. When hit, different things happen depending on what body part was hit. Getting shot in the leg causes you to move slower and drag your leg (complete with sound effects), and getting shot in the chests causes your gun to wobble around and your vision to blur, making it impossible to aim. The only way to heal your wounds is to apply bandages, sultures, and splints, (different medical supplies are needed for different wounds) which you must apply in real time, making doing this in the middle of a firefight next to impossible. However, you must do it really fast, because if you leave major wounds untreated, you'll actually bleed to death, where as minor wounds will heal by themselves. Also, there was no Hud at all. Meaning there was no health bar, no ammo indicator, and no crosshair. The only way to tell if you are dying is how much blood was on your screen, how grey your screen was, and how hard you were breathing in game. To keep count of your ammo, you have to mentally keep track of how many bullets you fired, and to aim, you have to aim down the actual iron sights on the guns. The only real unrealistic parts were One Bullet Clips, the ability to carry every weapon in the game simultaneously, the fact that applying a bandage will make any wound good as new, and that there are 7 foot tall alien fish men who would claw you to death unless you shoot them and giant sea gods you have to fight. On top of that, unlike a vast majority of FPS games, a weapon would not automatically plant a bullet at the center of the screen. Rather, it would depend on where the weapon's barrel was actually pointing, meaning that weapon sway is not merely for show. This not only applies for you, but for any mook with a gun as well.
- For a browser F2P FPS with a skill progression system, Contract Wars (as well as its remaster Hired Ops) is a pretty hardcore game. Move speed is limited, equipment is limited, weapons are inaccurate when moving, not aiming down sights reduces accuracy, recoil is generally strong, everybody goes down in just a few hits, sniper scopes are 3D scopes (meaning the view around the scope is not zoomed in), and even the effect of skills are minimal, with the health regen being surprisingly slow and the armor being generally weak against most firearms in the game. Gameplay can be described as being more "walk-and-gun" than "run-and-gun". Hardcore mode pushes the realism even further, with changes including averting One Bullet Clips, averting Critical Existence Failure, averting Friendly Fireproof, and trimming the skill tree down to a limited list of things that a PMC is reasonably expected to have in the field.
- The related game Escape From Tarkov (made by a heavily related but separate studio, taking place in the same universe) is ludicrously detailed in realism. The huge (and incomplete) list of realistic mechanics include common sights like no crosshairs, realistic inaccuracy and recoil, realistic bullet damage, magazine-based reloading, minimalist HUD, bullet penetration, realistic carrying (2 long guns and a handgun on your body, the rest goes in your backpack), massive punishment to deaths to discourage recklessness; some rarer sights like bodypart damaging, bullet ricochet, 3D weapon presence (your weapon is not locked to the center of your screen, you'll lower it when standing up against a wall, your sights can misalign if you move when aiming, and telescopic sights do not zoom in your entire view), fatigue from running and carrying, the grenade having a massive kill radius due to the shrapnel; and there are just some obscure mechanics that exist for no reason other than more realism, like requirement for gun maintenance (your gun can jam if you don't), having to put magazines in your rig before you reload, detailing weapon modification to such an extent you can strip your gun down to just a (non-functional) receiver, and making sure that there's a first-person player animation for everything you do (including changing your firing mode). The game also includes a whole bunch of realistic maneuvers like making tactical reloads separate from speed reloads and allowing you to lean and fine-tune that lean with scrolling. In short, it is created to be as authentic, hardcore, and detailed as possible.
- Counter-Strike: Mostly-realistic damage system (though you can move fine after being blasted in the leg), inaccuracy increases drastically if you don't stop and aim. Limited equipment to a primary weapon and a sidearm, and the interesting mechanic of bullet penetration found rarely in other games at its release. Also, no healing. Nor, in the classic game modes, respawning. Commonly said to be unrealistic since you never take aim with your iron sights, but that's because the game mechanics basically combined the accuracy of aiming down sights in other games with the first-person view of hipfiring, and characters do take aim in third-person. In practice, it's like if the game automatically made you aim down sights when you stop moving. On the other hand, the bunnyhopping exploit (which allows players to move faster while jumping in a diagonal direction) was so popular that players revolted against Valve for eventually patching it out of Counter-Strike: Source and attempting to go even farther in Global Offensive by penalizing excessive jumping in the beta, blaming the push for "realism" on the popularity of Call of Duty. Whether it's true or not, Counter-Strike fans definitely consider themselves "old-school" FPS players.
- The Delta Force series: Only a few hit points even with body armour and no Regenerating Health, the player carries one rifle, one sidearm and a couple of secondary weapons (mostly explosives), No "Arc" in "Archery" is averted, One Bullet Clips are averted and Unusable Enemy Equipment is in force.
- Ghost Recon: The original games have you die in one or two shots, and squad tactics are emphasized. The later Advanced Warfighter games rank lower, but are still Nintendo Hard (at least, the PC versions are — the consoles are much like their newer counterparts) and also have the option of playing on the original difficulty — that is, die in one shot.
- The Source Mod Insurgency: Modern Combat and its commercial release/sequel Insurgency. It features fully realistic firearms, as in all the firearms have a maximum range of several hundred meters. The main limiting factor is whether the player can even see the enemy, which is hard a lot of the time due to the long ranges (outdoors) and extremes of light (indoors), as well as all the smoke and sand everywhere. You can't see your ammo or health, and you have two methods of aiming: looking down the sights (which you will doing most of the time), and firing from the hip, where your guy freely waves the gun around rather than holding it in one position. Special weapons such as shotguns (which are effective at much longer distances than in most games), grenade launchers, smoke grenades, laser sights, and M4 assault rifles are only given to certain classes. Sniper scopes are also 3D scopes, only magnifying the contents inside the scope instead of just zooming in the entire view. Cover is very important, staying in the open will invariably get you shot. The best tactic is suppressive fire most of the time, and occasionally using grenades for flushing out enemies. Damage varies depending on range. The fully armored US soldiers can take only a few shots before dying. When shot, you'll flinch and the screen will temporarily turn red, and even near misses blur the screen to simulate suppression. Day of Infamy also sits right here due to having mostly the same gunplay mechanics, just in a WWII setting.
- Iron Storm: The game isn't a true tactical shooter per se, but still requires you to take precise aim, choose your gear wisely and carefully fight your way through enemy territory. Do Not Run with a Gun is paramount not only for achieving victory, but for basic survival as well, in each of the six campaign missions. Sighted Guns Are Low-Tech is zig-zagged — you can see them on every weapon, but can't really use them in-game and have to rely on traditional FPS reticules or a scope.
- Mafia: The City of Lost Heaven has guns that are very in-accurate when fired standing and when moving. Only allows you to holster one larger weapon. One Bullet Clips and the Short-Range Shotgun are averted, and pistols are very accurate and powerful. Health kits exist, but are very uncommon (only a few levels have one) and only regenerate 30 points. Enemies and player are fairly close in health. Reloading permanently discards partially used magazines (only the pump-action shotgun averts this which is reloaded one shell at a time).
- Medal of Honor: Warfighter's multiplayer mode is a lot slower than what one'd expect from a game in the footsteps of Call of Duty: Modern Warfare, and even Battlefield 3. Health regen is kept at a slow rate, weapon damages are high, there's significant recoil and spread to your shots, and the buddy system encourages teamplay. Combat in general is a lot less about running and gunning and more on the side of taking things slow and steady. The singleplayer however, stood firmly right next to Modern Warfare.
- Metro 2033: Different ammo types and attachments, gas mask is required for poisoned areas & the gas mask can break or run out of oxygen. Finally light affects stealth. For unrealistic elements, slowly regenerating health & made of iron except on hard and ranger hard difficulty, and the former is compensated by being really slow.
- No More Room In Hell attempts to depict a realistic zombie survival situation. The HUD is completely absent most of the time — no crosshairs, the ammunition count only appears when you hold the reload key to check the magazine, and you can only tell your health from the visual effects. Shooting without stopping and aiming is a bad idea due to the scarcity of ammunition and the low hipfire accuracy worsened by moving. No shooting when sprinting. Aiming for the head is a requirement since zombies can shrug off a ton of damage to their body due to being undead. Inventory is restricted by weapon weight (one shotgun takes up around a third of it), and the more you carry, the less stamina you have for sprinting and melee. Ammunition is separate for guns with different calibers, and also take up weight in your inventory. Getting attacked by a zombie can cause damage, bleeding and/or infection. Health is regained through first aid kits (going through a lengthy animated self-treatment process), bleeding is treated with bandages (no healing though), and infection is temporarily halted with antiviral medicine. You die quick if even just one zombie gets a bit too close. In addition, using a weapon with a scope doesn't zoom in the whole screen, flashlights can only be used alongside handguns since you have to carry them with one hand, and infected survivors will always reanimate after death unless they commit suicide with a headshot.
- Onward is a tactical shooter built from the ground up for Virtual Reality systems like the HTC Vive (and, later, the Oculus Rift with Touch controllers in 360-degree room-scale configuration), currently focused on 4v4 competitive multiplayer rounds, and leverages the use of hand controllers and room-scale movement in a number of ways:
- All of your equipment is physically found on your character's body somewhere, and must be grabbed by hand. This equipment ranges from your weapons and spare magazines to syringes to your shoulder-mounted radio and knife to a tablet that contains your minimap and hacking codes for objective gametypes. It's as diegetic as it gets.
- Just as diegetically, you have no crosshairs whatsoever, and laser sights are very faint in daylight, almost imperceptible. Aiming requires physically lining up the target through sights. Guns can be held with the off-hand as well in order to stabilize one's natural hand jitter that the controllers are sensitive enough to pick up on; some players do not find this sufficient and have built physical stocks to hold their controllers in, bracing themselves like they would a real gun.
- Taking cover amounts to physically leaning, crouching and going prone around objects. Not doing so is a great way to get shot.
- If you do get shot, but don't die immediately, your vision desaturates and you need to inject yourself with a syringe to stay alive for more than a minute or two. This syringe can also revive teammates who have been incapacitated, but not outright killed; these teammates are still capable of speaking out and show up on your tablet's minimap.
- Speaking of which, in-game voice chat is completely spatialized to the point that opposing players can hear each other in-game, and globally communicating to the rest of your team requires use of a shoulder-mounted radio. If you want to stay stealthy, stay silent!
- Reloading is done as realistically as the hand controllers can allow - new magazines must be physically grabbed from the body and moved into the weapon, and if necessary, the charging handle pulled when empty. It's a lot like Receiver in VR. Oh, and don't expect any physical indications of your remaining ammo count should it be above "empty"; count those bullets!
- Contrary to how a lot of VR games use teleportation to move as a countermeasure to some users suffering from nauseating motion sickness in VR with artificial locomotion, Onward uses conventional movement via the trackpad/stick on one of the controllers, albeit oriented to line up with the hand's facing instead of the viewpoint, since the alternatives would be too limiting or too unrealistic. Movement is fairly slow and deliberate even when "sprinting", however.
- The Operation Flashpoint series, the ARMA series and their professional derivatives Virtual Battlespace 1 and 2. The U.S. Army uses America's Army for recruiting, but when teaching tactics using networked computers, they use VBS 1, a modified version of Operation Flashpoint (or more recently VBS 2, modified from ARMA): Mainly infantry/dismounted combat; the ARMA series vehicle operating is actually towards Classic on the realism scale for gameplay reasons, with 'games' such as the Digital Combat Simulator series being even harder sim than ARMA in that respect.
- Operation Flashpoint is crushingly realistic. Reloading with a partially used magazine puts that magazine back into your inventory for later use but you can't see which magazine is it until you load it. Wounds are severe, and you're just as mortal as your enemies. Being shot in the head or upper torso almost always means instant death, and being shot in the limbs can render you unable to walk or fire accurately. Combat usually takes place outdoors in wide open areas, and exchanges of fire often take place at ranges of 300 meters or more. Bullets take time to travel and drop over long distances, and even sound takes time to travel. Such is the detail of the game world that you can navigate by the stars at night, and the tides and sunrise/sunset times change depending on the time of year.
- PlayerUnknown's Battlegrounds falls into this. Creator, Brendan "PlayerUnknown" Greene originally started the whole Battle Royale concept as a mod of ARMA after all. As such, the game encourages measured, strategic play over simply rushing into action and trying and getting into gunfights.
- Rainbow Six: The early entries forced you to make tactical decisions and aim carefully — both you and the terrorists were easily killed, even if you were wearing heavy armor, which was useless against the common AK-47. You had to spend quite a bit of time planning which floors to breach and who to kill in the pre-planning stage, and you had to make it quick, since most missions had hostages in them. Later entries were less realistic, culminating in Vegas, which has a CoD-style healing system and arcade-y single player, with no pre-planning [except for gear loadout].
- Rainbow Six Siege pulls the gameplay realism slider back towards the realistic side a bit. Thematic weirdness aside (the game's main game mode is multiplayer and features multinational special forces engaging other multinational special forces), no automatic healing, short time to kill, no respawns, high weapon recoil and high inaccuracy when moving or not using sights, finding cover is emphasized and Concealment Equals Cover is averted, creating a generally realistic gunplay. A big bonus is the addition of a highly detailed and realistic if slightly exaggerated procedural destruction system, allowing surfaces to be destroyed for new viewing angles or even pathways. Tactical gameplay is more or less back (though not in the same way the original games did) with information gathering through drones, cameras, and sounds being heavily emphasized in the metagame. The Operator gadgets are questionable in terms of realism though mostly somewhat grounded in existing concepts. The Tactical Realism mode further drives it towards the realistic side by having a realistic magazine-based reload system (averting One Bullet Clips) and also removing many many HUD elements.
- Red Orchestra: A very harsh portrayal of WWII combat. There are no crosshairs and, when fired from the hip, weapons are not centered to the screen, but wander back and forth as you move. There is no ammo counter, few HUD elements in general, and no healing at all. All weapons have significant recoil that must be carefully controlled when firing rapidly. Weapons can be rested against surfaces to steady them, and weapons with bipods (such as machine guns and anti-tank rifles) can be set up on any suitable surface. Ballistics are fairly realistically simulated with travel time and bullet drop, though no penetration (Fixed in the sequel). Machineguns overheat if fired in long bursts, even to the point of warping and ruining the barrel. Sniper scopes only magnify the things you see in them instead of zooming the whole screen in. Damage modeling is severe and universal and one hit kills are common, especially if a person is shot in the head or torso. Wounds bleed, shrapnel takes arms and legs off, and direct hits from artillery shells can turn men into a red cloud. Combat is highly tactical, and which weapon you're given depends on your class. Since all classes except "Rifleman" are limited in number, most soldiers end up with a bolt-action rifle or, if they're lucky, a semi-automatic rifle or submachine gun. Cool Guns like sniper rifles and machineguns are limited in number and must be used wisely.
The game also approaches simulation level in its portrayal of tanks: Crew of One is averted, a tank must have at least a driver and a commander/gunner to be used efficiently. It's almost impossible for the gunner to aim the cannon while the tank is moving, so voice communication between gunner and driver is a must. There is no third person view, so the tank crew can only see through small view ports. To get a better view, they have to open the hatch and risk being shot in the process. Tank armor varies in thickness depending on the model and part of the vehicle, with rear armor being the weakest. Tanks can be disabled by penetrating the engine compartment or disabling the treads, or completely destroyed by aiming for the ammunition storage compartment. Shells that impact tank armor at a sharp angle will deflect off harmlessly.
- S.T.A.L.K.E.R.: Shadow of Chernobyl and its sequels — Realistic "tactical shooter"-style combat, with lots of firing while crouched, usage of ironsights and leaning around corners. Notably, bullets are affected by gravity and can also ricochet off surfaces. Healing items are in limited supply, but are insta-heal. You can only carry a very limited amount of stuff (50 kgs), and can only equip 2 firearms at a time (a pistol/small submachine gun and a larger weapon). Unless you're wearing military-grade combat armor, expect to die after only a few shots from an assault rifle. Each individual enemy is also just as tough as the player character, so a Mook wearing combat armor can soak more than half a mag of assault rifle fire before going down. However, weight doesn't affect movement until you go over the limit, and medkits heal instantly. (The game would be a LOT harder [hard as it already is] if it wasn't.)
- SWAT 4: Being a slower-paced and atmospheric tactical shooter, there is no jumping at all, you can either creep, walk at a standard pace or run very slowly. Crosshairs and the basic personal HUD are minimal. There is no healing for anyone. Single shots are often lethal, and even when they're not, being shot in the legs or arms will hurt speed or accuracy. The player can daze himself with his own flashbangs and stinger grenades. There are no frag grenades, explosive charges, rocket launchers, grenade launchers, light machine guns, anti-material rifles, or BFGs of any kind, with the most powerful weapon you can carry being the military grade M4A1 Carbine, and all the grenades (tear gas, stinger, flashbang) being non-lethal, which fits given that SWAT is a paramilitary police unit, not part of the army. All weapons have a fully realistic portrayal of recoil and their respective drawbacks. In fact, the only thing not portrayed is bullet ricochet. It's possible to customize one's bullet loadout (full metal jacket or jacketed hollow-point, etc.), and there's a focus on non-lethally neutralizing and apprehending criminals, rather that killing them outright. You're also punished for not following SWAT procedures, so if you shoot a perp without first ordering him to comply, points are docked for use of unauthorized deadly force. There are no saves at all, during any mission. The less-lethal flash bang and stinger grenade actually can injure or kill if detonated within close proximity to a person.
- World of Tanks: Realistic loading times, relatively historical modelling (with some changes for gameplay — slower turret speeds on US Tank Destroyers, for example), extremely detailed ballistic physics. No health regen, although you can usually take multiple hits without dying. Aversion of Critical Existence Failure (Although it can technically happen, most tanks end up tracked with some crew members dead long before the whole tank gives out), a spotting system, and what can be considered the closest tanks can get to a Cover Based Shooter with Camoflage and hiding behind rocks and buildings being key to victory.
- World War II Online: Battleground Europe is a punishingly hard combined arms MMOFPS with a physics engine that includes full flight modeling, ballistics and vehicle damage models. The game is also heavily focused on teamwork and it is not uncommon to see operations pre-planned with marked artillery positions, infantry attack paths and other such stuff. The developers were even contracted in 2006 to produce a PC-based modern-day battlefield simulator for the British Ministry of Defence.
- in Receiver, every little aspect of the gun you're holding can and must be manipulated, from turning the safety off to checking if a bullet is loaded in the chamber. It averts One Bullet Clips by making you manually put each bullet in; you carry all clips, empty or full with you at all times; you must either remember or check the amount of bullets you have left; you can point your gun and aim anywhere on the screen; the flying robots that you fight realistically react to where you shoot them; and you play as a One-Hit-Point Wonder.
- Project Reality is a mod for Battlefield 2 in which the realism is taken up a notch. There is little more than a compass for a HUD, all guns kick like a mule, and weapon reloads are painfully slow.
- Verdun: Many aspects of World War I and real warfare are replicated with the game mechanics. Squad combat is required, weapons do extremely high damage, and whatever damage you do survive takes thirty or so seconds to recover from, and reloading is slow. Combat focuses heavily on using tactics and teamwork, and almost everything on the battlefield is looking forward to killing you.
- Airsoft skirmishing can be considered all over the scale.
- Realistic-looking weapons (but with completely different ammo capacity and ballistics), more powerful weapons are often given minimum range restrictions to avoid injury (eg. a sniper being disallowed to fire on an opponent within 20 meters, and forced to switch to a sidearm - some fields force players to surrender to another if they're within ten feet, and so on), grenades and traps are different, cover and stealth encouraged, accuracy depends entirely on the shooter and their equipment, et cetera.
- Play styles and site rules vary from casual skirmishing featuring lives, spawn areas, no restrictions on ammo capacity/rate of fire, and classic game types such as capture the flag and simple team based death matches. To mil-sim style play, incorporating real capacity magazines, team based camouflage and uniforms, and complex and variable objectives.
- Certain manufacturers such as Systema produce premium brands of replica weaponry specifically for military and law enforcement training programmes. Featuring exact weights and dimensions (loaded & unloaded), correct fire rates, identical construction design regarding maintenance take down, replicated features such as burst fire modes and special safety options, and even ejecting shells. Conversely, a casual skirmish field can witness a sometimes chaotic and even bizarre mix of custom equipment, with certain pistols capable of out ranging lesser sniper rifles, large magazines carrying 5000+ rounds, modified guns firing at up to 3000+ rounds per minute (A real rifle avg ROF being in the range of 600 to 800), automatic desert eagles, grenade launchers mounted on pistols, pistols mounted on rifles, and cut down rifles mounted on rotary grenade launchers.
- While paintball is somewhere in the "unrealistic" area, you may not survive more than one direct shot (most rules state a quarter sized glob of paint is considered "dead"), which is probably somewhat realistic. You could catch a lucky break, though, if the size of the paint glob isn't large enough.
- Laser Tag, on the other hand, falls squarely in the Classic category. For starters, we have laser guns with Bottomless Magazines, very small hitboxes (depending on the system, there are typically sensors on the torso, head, and/or gun), and near-instant respawning. Add to that a darkened arena with glowing, UV-sensitive decorations and generally loud and fast music, and you've got something almost right out of an 80's arcade.
