Abbreviation for the game 'counter strike source'. Cs:S is 100% leeter than normal CS, and there are less cheats too.

an add on for the game Half life 2. built off of the source engine this game was supposed to be good but is plagued by random headshots, bouncing off of barrels, and huntchback characters. c.s:s is the "next" version of the ever so popular counter-strike. Not surprisingly, c.s:s has failed.
