"Colonial Marines is a staggering mess of a game. "
That seems more than a bit hyperbolic. It's a crappy game and disappointing somewhat like Homefront. It's better than Rogue Warrior. But a staggering mess? No. Not really. Certainly not in the way I would use those words. Big Rigs? Yes. Emphatically. A:CM ? Not so much really. It's merely a Blacksite: Area 51/Dark Sector sort of game where one hoped for more of a near Bioshock.
