npc_antlion_template_maker is a point entity available in  Half-Life 2 series.

Seeing as antlions were frequently used as cannon fodder in Half-Life 2, especially within Nova Prospekt, this entity is used to efficiently monitor and respawn antlions on a continuous basis. It has similar functionality to a npc_maker.
