Good FPS games?

Counter-Strike: Source and MW2 are still the best FPS games out there.

Team fortress 2 it's the most fun you will find online for sure , and since it's different from most fps , it's fun to try sumthing new , also u should give bulletstorm a try , realy fun game

Honestly I really enjoyed the single players of MW3 and BF3, (yes, you can like both games). Multiplayers to me are fun, but there is always that one guy with a MP7 Rapid fire walking around killing everything in sight because he spent half of his life playing it.

Other then that, Hotline Miami is one of the best one's I have played by far.
