Tick (Doom 3)

The Tick is a small, spider-like enemy in Doom 3 that has similar attack patterns to the Trite. They rarely appear, but they usually come in giant swarms. An example of this is found when the player reaches goes to a weapons cache on the level just before that in which he fights two Hell Knights for the first time.

The only noteworthy differences between Ticks and Trites are aesthetic ones (although the Tick can jump slightly farther than the Trite). While Trites resemble an inverted Lost Soul with legs, Ticks appear more insectlike. What's more, while the Trite makes a deep, throaty roar, the Tick makes high-pitched chirps. Finally, while Trites curl up and burst into yellowish-green "spider juice" upon death, Tick corpses burn away like all other demons.
