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 returns from Hell to Delta labs.

The only real differences between Ticks and Trites is the model, skin, and sounds used. Ticks also burn away like normal demons; Trites explode with spider juice.
