Background:
Marathon Infinity is the third in the Marathon series, a first-person shooter in which you are a human cyborg marine whose mission is to save humanity. In Marathon you met the aliens as they invaded a colony ship. In Marathon 2: Durandal you battled an insane Artificial Intelligence called Durandal.

In Marathon Infinity, you try to solve clues to learn the secrets behind your own existence, all the while battling the Pfhor. The game uses the Marathon 2 engine and offers new weaponry, such as the KKV-7 10mm Flechette SMG. The game features the 30-level scenario Blood Tides of Lh'owon with new textures, landscapes, and monsters as well.
