Alien Swarm: Reactive Drop is a co-operative top-down shooting game. It is very easy to learn, but quite difficult to master. There are bunch of campaigns that you can do, and do again, and do again. You may get bored eventually, since it may get repetitive, but it is still interesting to keep on repeating until you improve your time. The community is also nice, and I met lots of people thanks to it. I would recommend it for those who want to play a co-op game with friends, along side Left 4 Dead 2.
