Telefrag
A telefrag is a frag involving teleporters, when one entity teleports into space already occupied by another. This can also occur when one player respawns in the same location as another player. Many computer games cannot handle two characters being in the same place. Those games handle this by destroying the player who initially occupied the spot, leaving place for the player teleporting in. The character who teleported in is said to have telefragged the other.
The first first-person shooter game to display telefragging was Doom, though the phenomenon predates the fragging video game term as it was found already in the 1985 arcade game Gauntlet.
Generally, a teleporter's endpoint is not visible from the entrance. This makes telefragging a matter of chance in many games. Therefore, cooperative planning between two teammates on opposite sides of the teleporter should use go-codes to indicate if a potential telefrag is lurking toward the teleporter. In such games, being telefragged is often seen as annoying. Some games have incorporated telefragging as a conscious gameplay element, however. Unreal Tournament (and its sequels) allows players to use portable teleportation device (known in-game as a "translocator") to frag an enemy player by creating a teleport exit underneath the target player, and then teleporting over him. However, if a player attempts to teleport to his or her teleportation device after it has been destroyed, the player who destroyed it is credited with a telefrag.
