Good game worth playing! Multiplayer works well very well and is fun.
Having said that, every once in a while the camera angle gets annoying, but this is a usual problem to me with top view games. You want to be able to look down a hallway to see what's coming but can't because of the camera angle. This leaves you feeling vulnerable, but then you realize the bad guys aren't that hard to deal with anyway.
Really, this is the only negative I have found with the game, as long as you don't take it too seriously. Remember, you're playing an arcade style game that is just shy of being a button mashing fest. The story isn't too in depth, but is interesting enough to want you to find out what's happening next.
