SoF2 is my favourite online game. Much much better than CoD or any other shooter game. With great modding community, community-made anti-cheat and the best gameplay where moves like leaning has strategical significance,you can throw knives and all kinds of stuff, there are 1st/3rd person modes and servers, and great mods like Hide&Seek and cops and robbers.

This is a Screenshot of me after I've killed like 5 or 6 guys with AK bayonet in H&S Cagefight.
Try it if you're bored of mainstream games like CoD and want something hardcore.
