And that's Colonial Marines' biggest problem: enemies come, and you shoot them down easily, again and again. The game is remarkably light on variety. A couple of battles masquerade as boss fights, but they require no strategy and are just as easy and thrill-less as the rest. The four- to five-hour campaign has no thrust to it; it feels the same from beginning to end, and the finale just drops with a thud. And by being so easy and predictable, the game lets down the license.
