History YMMV / Wolfenstein3D

** Episode 3, level 8 is a huge pain in the ass as well, with lots and lots of ambushes. The biggest offender, though, is the giant swaztika room at the start, along with the rooms surrounding it, all swarming with Officers and SS'es. Make even the slightest noise, and they ''all'' converge on you at once from all directions (with even a few enemies from adjacent rooms joining in.) And even if you think you've killed them all, the levels are set up to stagger their arrival, so there's probably still one or two more wandering around, waiting to get you when your back is turned.

* DemonicSpiders: The mutants, especially in groups of three or more. Mutants do not make a noise when they see you. They can also shoot you as soon as they see you. Every other enemy in the game will make a noise when they see you and take a brief pause before shooting you.

** e6m9 is the boss level of Episode 6. For some players, it can be ThatOneLevel, but for others, it's a balls-to-the-wall slug-fest where you mow down an army of Nazis and then face of against a pretty interesting boss. If you enjoy rooms packed with a lot of guards to mow down, then this level is probably your thing.

* CrowningLevelOfAwesome: There is no "right" answer really, but here are some possible favorites:

* CrowningMomentOfFunny: Probably for amusement, the coder of the game engine made it so that every once in a while, when one kills a guard or dog, they emit the sound flatulence. It can be jarring to suddenly hear it while going about your business as usual. This troper tends to encounter this "EasterEgg" during secret levels.

* GameBreaker: For the patient players, it is possible to safely clear out many rooms of guards by diagonally stabbing the knife into a doorway (or almost any 1-square-wide 90-degree blind turn) as the [[ArtificialStupidity Nazis dutifully come through single-file to their deaths]]. It is a sound strategy for beating the otherwise-not-100%-completable [[BrutalBonusLevel E4M10]].[[note]]This only works for levels that contain rooms that force the guards to funnel through a single passage, if there are two near-by doors, then you are not as safe from sneak attack.[[/note]]

* ThatOneLevel: Episode 6, level 9 from the original game and levels 16 and 18 from ''Spear of Destiny'' qualify, due to the swarms of guards [[DemonicSpiders (including mutants)]] that occupy the rooms of level 16, and the [[ThatOneBoss Death Knight]] plus the fact that you start in a very disadvantageous room.

** Episode 6, level 7 has a bad reputation as well.

* UnwinnableByInsanity: In certain places, such as the health room in [=E2M9=], you can push a secret wall and then quickly run into the square it is destined for. If you succeed, the wall parks on top of you. Congratulations, you are now stuck in a wall, totally immobilised, treated with a view of broken vertical lines and with enemies unable to shoot you, hence no way of dying.

** Episode 6, level 7 has a bad reputation as well.

* FanNickname: Pushable walls were quickly christened "pushwalls".
* FridgeLogic: How come the mutants mingle in just fine with the regular guards when they're hinted at to be killing machines and slaughtered some of the guards offscreen in episode two? (What I mean is that they don't care if any of the regular guards are in the same room they are and just focus on the player instead)

** The GBA port, which was more mangled than the ''{{DOOM}}'' port despite being a less complex game.
