Tick (Doom 3)


 * This article is about the Doom 3 enemy. For the timing unit in in the Doom engine, see tic.

The tick is a small, spider-like enemy in Doom 3 that has similar attack patterns to the trite. They appear only once in the Delta Complex, but they come in giant swarms. An example of this is found when the player reaches a weapons cache in Delta Labs just before that in which he fights two hell knights for the first time. In Doom 3: Resurrection of Evil, trites are encountered several times throughout the game, their last appearance in Hell.

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 insect-like. 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.

The tick cannot attack you while you're on a significantly higher vertical plane. For example, if a tick is on the floor, you can render it harmless by jumping onto a bunk bed. If closely examined a little human face can be seen on its head.
