Yes, it's another endless runner. Just hold on a second, though. The Great Martian War is a nice looking game, and the setting is really interesting. The year is 1913 and Earth has been invaded by Martians, War of the Worlds-style. Oh, and the History Channel is involved. Why? Aliens.
You play the role of a lone scout, or chump, as your commanding officers probably say. The goal is to weave through the oncoming waves of Martian invaders without getting blown up or running into anything.
