info player deathmatch
From Quake Wiki
The info_player_deathmatch entity is used to define the respawn points used in deathmatch mode. Players entering the game, and respawning after being killed will be placed at one of these entities.
There is no upper limit on the number of info_playe_deathmatch entities that can be placed, but at least one is required in order to test a level in deathmatch, and a larger number should be used in order to prevent frequent telefragging and make spawn camping more difficult. Generally speaking, larger levels that support more players should have more respawn points than smaller levels, and even for 1-on-1 maps, 5 or 6 is the suggested minimum.
