Telefrag

From DoomWiki.org

Demonstration of a player being telefragged and thrown away at high speed, which only occurs when the two things are touching each other's edge.

A telefrag is a special kind of frag or kill that results when a player or monster stands on the location of a teleporter as another player teleports to that location. The monster or player who was originally standing at that location will instantly die. Telefrags can be strategically used by a Doom player to kill powerful monsters without using any ammo (one example is on level E4M2: Perfect Hatred, a player can enter a secret teleport to telefrag the Cyberdemon). Monsters are usually not permitted to teleport to a space that is occupied, preventing them from telefragging. The only situation in which they are permited to telefrag a player is when they try to teleport in MAP30 of any WAD, because it is needed by the spawn shooter cubes to spawn a new monster, so it will not get stuck inside any other (some source ports allow the player to remove this exception or apply it to all maps). A player who is invulnerable or using the God mode cheat will not be protected from telefrags. A barrel that is placed on a teleporter destination can be telefragged and will explode as if it were shot, with the incoming player teleporting into the center of the explosion.

Utilizing an intentional telefrag is considered cheating in a UV pacifist speedrun.

Technical[edit]

Invulnerability or "invincibility" only protects a player from attacks doing less than 1000 points of damage, whereas a telefrag inflicts 10000 points (see the function P_DamageMobj in p_inter.c). The Doom source code refers to a telefrag as a "stomp".
