History GoodBadBugs / SurvivalHorror

** Fixed in a recent patch along with many other memorable glitches. On the upside, in Versus the Infected got a status bar!

* ''VideoGame/ResidentEvilCodeVeronica'' has two {{game break|er}}ing glitches so easy to activate it's ''insane'' they were missed during bug-testing:

** The knife ignores MercyInvincibility if you aim down. That's it. It will connect with its target three or four times per swing, easily doing as much damage as ''the shotgun''.

* ''VideoGame/ResidentEvil4'' had several that were BoringButPractical such as running at 1.5 times his normal speed by switching to the [[ShotgunsAreJustBetter Striker]], raising it and then quickly equipping another weapon before the laser sight could activate ([[http://speeddemosarchive.com/ResidentEvil4.html useful but cautiously used]] in [[SpeedRun speedrunning]]). However, the most memorable is Ashley's abilty to [[TookALevelInBadass suplex enemies]] by [[https://www.youtube.com/watch?v=d0Tg1btDrMA whacking them with a door]]. It's also possible to open locked doors from the wrong side with the TMP equipped to bypass entire "find the key" [[FetchQuest Fetch Quests]], pressing L + R before every PressXToNotDie moment which (most of the time) makes the other button prompt appear, and being able to push Ashley through the scenery by getting her into a corner and pushing against her when she ducks (useful for keeping enemies off of her). Also, the gimmick where Ashley scolds you for looking up her skirt is literally set to trigger ''anytime'' Leon's eyes aim up in that direction: even when he's been knocked down by an enemy or his [[SugarWiki/FunnyMoments severed head rolls between her legs]].

** Using an invincibility cheat in ''VideoGame/DeadSpace2'' and getting damage that the game says should kill you can lead to Issac [[https://www.youtube.com/watch?v=LCHlTtBy8R8 running around as a mutilated torso]].

** Also, although Monty is supposed to be immune to the camera thanks to his sunglasses, due to a glitch it serves as a "get out of capture free" card against him if you get the timing right. If you set it off with ''just'' the right when he grabs you he'll just sort of... stop, let you go, and wander away. It renders him a complete non-threat.

* ''VideoGame/ResidentEvil3Nemesis'':
** The "corner bug" when fighting the eponymous Nemesis in the police station. If you lured Nemesis into a small office in the meeting room (next to the evidence room) and backed into the corner next to the book case then Nemesis would get stuck on the book case while trying to run at the player, keeping him just out of range to attack (unless the player is standing with the knife readied to attack and even then he'll only attack on his initial charge) but allowing the player to attack him without getting hurt, even with their knife. He does eventually get unstuck but he can be lured out and back into the small office and this bug can be repeated until he's dead. This is the only viable way to beat Nemesis inside the police station without using a lot of ammo or healing items. There's a similar bug in the three-way intersection leading to the cable car in downtown where Nemesis can get stuck on a corner; unfortunately, this is only in the Japanese version. In all English versions this corner bug has been fixed.

** There's a ''very'' rare and harmless glitch where one of the Drain Deimos in the alleyway with the hanging crate will appear at a very tiny size as if it was an infant creature. Because it's so rare it's almost never commented on and is incredibly unnerving to encounter during a playthrough, messing with the player's head and adding to the overall tension of the game.

* ''VideoGame/{{Subnautica}}'' has several of use to speed-runners:
** Exiting a flooded base with an active Seaglide applies the Seaglide's speed boost to itself ("super Seaglide").
** Mobile Vehicle Bays can be used to clip through cave walls.
** A Mobile Vehicle Bay in a cave will load before the cave does and travel to the surface unaided for retrieval ("a wild Mobile Vehicle Bay appeared!").
** Partly deconstructing and rebuilding a Moon Pool builds a second Moon Pool in the same location, doubling the materials from deconstructing them (repeat as necessary for Matryoshka Moon Pools!).
** Clipping a building into a large wreck will cause it to despawn, revealing the goods inside.

** The TAAAAAAAAAAANK Mutation in VideoGame/Left4Dead2 was a VS mode in which all the Infected players spawn Tanks, all the time. The bug appeared when playing Dead Center. At some points in the first map, there aren't enough places for a Tank to spawn both out of sight of the Survivors and close enough to actually attack them. This lead to Tanks spawning in places outside the building, in mid air, 30 stories up, and falling to their instant deaths.

** ''VideoGame/ResidentEvil5'' had a glitch where you could load guns using the inventory... even if they were the gun you had out. In multiplayer, this allowed skilled players to reload near instantly, circumventing the weakness of many weapons and making chaining combos together a lot easier.

*** This exploit came back when No Mercy was ported to Left 4 Dead 2, but made tons easier since the said door in question could instantly break from any melee weapon used on it. It took valve at least three to five patches to finally plug the exploit, which Valve wrote in the release notes regarding the issue to say [[CrowningMomentOfFunny "Fixed the fix of the fix of the fix of the door exploit in No Mercy"]]

** Other classic bugs include [[http://img523.imageshack.us/img523/5834/l4dvshospital05rooftop0gy8.jpg hanging over non-lethal drops]], ability to die while in spawn mode as an Infected, ability to kill yourself by crouch-jumping at odd angles as a Survivor, [[http://img254.imageshack.us/img254/8721/l4dhospital01apartment0ku3.jpg bots that can help you up from halfway across the room]], AI director spawning infected in sight of the Survivors (it's not supposed to), [[http://img176.imageshack.us/img176/2617/path2tanktz9.jpg SPIDERTANK]], etc.

* In both ''Amnesia'' and ''Amnesia 2: A Machine for Pigs'' the player can finesse to '''on top of''' the nemesis monster, rendering it completely unable to reach the player. LetsPlay/SpoilerWarning demonstrated this in specials for both games, and found it hilarious enough to declare it a win-state and quit at that point.

* ''[[SilentHill1 Silent Hill]]'' has a bug where using the bottle of aglaophotis on one of the Stalker Larvae at the Lake Side Amusement Park skips the confrontation with Cybil and goes straight to the (graphically glitched but otherwise unimpaired) cutscene where the parasite is removed. Its handiness in aiding attempts at ten-star ranks and speed runs has made it well-known amongst fans.
** In the second game, there's a mini-glitch during James's battle with Eddie, where he seems unable to move or attack, allowing James to easily destroy him.
** The best is perhaps the glitch in ''SilentHill4'''s Building World revisit that lets you bypass bringing Eileen through the Door of Time like you normally have to, which means not only bypassing the script that spawns monsters in the area but also bypassing all the monsters you have to save her from before then.

** Let's not forget some of the other classic bugs, like [[http://img523.imageshack.us/img523/5834/l4dvshospital05rooftop0gy8.jpg hanging over non-lethal drops]], ability to die while in spawn mode as an Infected, ability to kill yourself by crouch-jumping at odd angles as a Survivor, [[http://img254.imageshack.us/img254/8721/l4dhospital01apartment0ku3.jpg bots that can help you up from halfway across the room]], AI director spawning infected in sight of the Survivors (it's not supposed to), [[http://img176.imageshack.us/img176/2617/path2tanktz9.jpg SPIDERTANK]], etc.

** In that same game, thanks to the way the flame mechanics were coded, it was possible to burn multiple zombies with one dose of kerosene as long as their corpses were touching. By luring and killing zombies so they fall onto one another, it is actually possible to kill every zombie in the game and only ever deal with the two unavoidable [[DemonicSpider crimson heads]] that appear in the game. As of the HD Collection it's officially an AscendedGlitch: you get an achievement for burning every corpse in this manner.

* ''VideoGame/{{STALKER}}: Shadow of Chernobyl'', a notoriously buggy game, had some good glitches:
** The game world is littered with anomalies that cause damage to the player. The player can get artifacts that increase damage resistance. Once you have the rare artifacts necessary to bring damage resistance over 100%... the once-hurtful anomalies not only heal you, but repair your armour. With no way to repair quickly-degrading objects in the vanilla game... hell yeah.
** At some point in development, the devs decided to remove vehicles from the game. Installing mods can restore the driving feature though. Anomalies that usually pick up the player and turn them into mush affect vehicles differently; they toss the cars through the air, sometimes at great heights and distances, over buildings etc.
*** It's also possible to drive the vehicles without the mod through careful use of clipping. ''Hilarious. Hell. Breaks. Loose.''
*** One of the side-effects of removing vehicles is that they never properly coded what happens if a player comes across one and tries to use the ridiculously-powerful knife on them. As such, the vehicles that are still in the game can be destroyed by stabbing them ''one time''.

** In ''Call of Pripyat'', a character named Crab is scripted to stay laying in a bed on the Skadovsk until you complete a particular side quest midway into the game. Sometimes when you load a game where you saved on the Skadovsk, Crab can be found out of bed. [[http://www.youtube.com/watch?v=FkpFE19-4CA He then starts living up to his name]]. It's as hysterical as it is [[NightmareFuel terrifying]].
