For those on the fence: if you like Army of Two, you'll like this.
I am glad I didn't buy it, but I'm also glad I decided to rent it. It's pretty fun.
A few faults: I want a flashlight, I wish I could give my teammates items, I hate snapping to cover automatically, and I wish I could carry more than one first aid spray.
It's not very Resident Evil, but it's still pretty fun. Like I said: if you enjoyed Army of Two or 50 Cent: Blood in the Sand, you'll enjoy this.
