Pretty decent Halo clone with a little Red Dead Revolver and other shooters thrown in there for good measure. It's not nearly as good as Halo, of course, but it's pretty fun and inoffensive overall. I enjoyed the atmosphere and licensed soundtrack, though it did take itself a little too seriously. The story was okay, though the good ending was kind of lame because you get no hoes. There are some good levels, and some pretty awful sections of the game like the mission where you are in the sun and your powers are nerfed beyond belief, or the mission where you drive a knockoff warthog from Halo that controls like complete garbage. The suicide bomber enemies are also fairly annoying because they can spawn right on top of you, the jumping is extremely floaty and difficult to control, and the bosses kind of suck because you only get the worst guns in the game to fight them and Jericho moves frustratingly slow in reaction to their moves.
