monster_alien_controller

Alien Controllers are one of the few flying monster entities in Half-Life.

monster_alien_controller is a point entity available in Half-Life, Half-Life: Opposing Force, and Half-Life: Blue Shift.

A monster_alien_controller is a hostile alien NPC with the ability to fly and shoot purple energy projectiles at the player. Because an Alien Controller is a flying monster entity, it requires info node air point entities to navigate properly. Unlike most monster entities, an alien controller is not gravity affected, meaning that if it is placed mid air in the editor it will spawn at that location mid air in-game.

Note:Some keyvalues, spawnflags, or effect flags might not affect an monster, based on the functionality and coding of the monster.
