A tick, from Marathon 2
The tick is a strange, parasitic creature native to Lh'owon, and first encountered in Marathon 2: Durandal.
Normally, ticks flitter about in the air, seemingly oblivious to the player. Usually nonaggressive, they serve only to obstruct the player's path, and to slightly clutter the motion sensor. On higher difficulty levels, however, the ticks will explode in a fiery cloud when destroyed.

Tick sprites, Marathon 2
- Several different types of ticks were originally conceived for Marathon 2, including the Energy Tick and Oxygen Tick. For the final release, however, the ticks neither attack, nor do they appear to adversely affect the player's health or oxygen levels.
