A quick review of a surprisingly addictive XBLA title.
From the review: "For your 800, well earned points, you're getting a lot of content. On top of the 45 episodes, each containing 5 levels, there are also co-op specific levels for up to 4 players, leaderboards, a level editor, survival and race multiplayer game modes.
The co-op levels are brilliant. You'll have to open doors and lure enemies for your buddy, but often you'll be completely sealed off from each other. Like the main campaign, they do get plain sadistic at times leading directly to my lack of hair and fingernails. "
