2. Story-driven and violent FPS for the Xbox (and most recently the PC, and pretty soon the Mac) in which you take on the role of Master Chief, a genetically enhanced super soldier fighting alongside the UNSC marines in an attempt to save humanity from the wrath of the Covenant, a strong religious alliance of at least six alien races hell bent on destroying the human race, most likely because they fear our moral corruption and lack of discipline, among other things.
Halo's story is complex and interesting, at least until its plotlines start showing up in other games.
