Counter-Strike: Global Offensive launched last month on the PSN to some amazing sales, even finishing at the top of the pile for the entire month. Now, Valve has officially announced that starting Monday, the first of October, a big update for the game will be rolled out.
The update will include a revised matchmaking system for Classic Competitive mode, two maps (de_vertigo and ar_monastery), and numerous bug fixes that were reported by the community.
