Over at the Penny Arcade Expo, Valve have been busy showing off Counter Strike: Global Offensive, the new incarnation of the shooter for PC, XBLA and PSN.

We already have some confirmed maps -- Dust, Dust 2, Aztec, Office, Nuke, Italy and Inferno. The matchmaking system set up for the console versions will be 5 versus 5, and will include an ELO-based ranking system to determine your skill level. There's also a few new weapons, including a Molotov cocktail and a Stun Gun. Also, no TF2 style hat nonsense!
