Before they rose to fame with a little known game called Halo, and it’s equally unknown sequel Halo 2, Bungie was best known for the Marathon trilogy of games. Essentially a precursor to Halo in many ways, you played a cybernetically-enhanced soldier thrust into an intergalactic battle between ancient alien civilizations, insane AIs, and a little something called the W’rkncacnter.
I never played the first Marathon game too much, but I loved Marathon 2: Durandal and Marathon Infinity, spending many hours hunched over my PowerBase trying to figure out what Durandal was up to. And it looks like I’ll have a chance to do it all over again: the entire Marathon trilogy is now available as freeware.
