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. There's little suspense, nothing to absorb you or spur your curiosity. Colonial Marines is tone-deaf to what makes the Alien franchise what it is--and what makes the best shooters so exciting.
