− | Suicide Exit (also called Deathslide) is a technique where the player intentionally kills the character to exit a level. Dead actors in the Doom engine acquire momentum on death by a weapon (which will have a degree of knockback) or by a nearby explosion. The engine considers a corpse to have 0 height, so a dead player can slide their corpse under locked doors and into otherwise unreachable places which can trigger a level exit. This was discovered in 2001 by speedrunner Vincent Catalaá. More information, including techniques and demos, can be found [http://doom.wikia.com/wiki/Suicide_exit on the Doom Wiki]. | + | Suicide Exit (also called Deathslide) is a technique where the player intentionally kills the character to exit a level.

| + | When moving along a north/south or east/west wall, the player can move against and along the wall (ie: by straferunning into it) to accelerate to a very high speed known as a wallrun. This occurs because the engine recognises the player runs into a solid object and attempts to "slide" the player along the object, as coming to a sudden stop the instant you touch a wall is not very plausible. However, no check is made to see if the player has already "slid" against a solid object. Given the right angle, a player can "slide" two times per check resulting in achieving double movement speed. |
