Floor Turret


npc_turret_floor is a point entity available in Half-Life 2 Half-Life 2, Half-Life 2: Episode One Half-Life 2: Episode One, Half-Life 2: Episode Two Half-Life 2: Episode Two, and Half-Life 2: Deathmatch Half-Life 2: Deathmatch.

It is unstable and falls over easily, but cannot be destroyed. It scans a 120 degree area, and will lock on to and fire at a target until that target goes is out of range or can't be seen.

When knocked over, the turret will fire randomly for a few seconds then disable (much like the floor turret from Portal). However, unlike the Portal turret, it will switch on again after being placed upright.

Playtips

  • The player can pick up the turrets with +use key or with the Gravity Gun. While active, the turret will be hostile to zombies and npc_headcrab. When held pointing away from player, will alert and take aim at enemies.
  • Turrets can be carried through doorways and sometimes through level changes.
