Valve has released this debut trailer for Counter-Strike: Global Offensive. They also confirmed some information to Kotaku about controls and online play.
CS: GO will feature the PC/Mac controls that players are used to. PS3 players will have the option of using the Dualshock controller, the PlayStation Move, or a keyboard and mouse. Xbox 360 players will be able to use the console’s regular controller only. For online play, Valve is working on including cross-play between PC/Mac players via Steam and PS3 players. Unfortunately for Xbox Live users, they’ll be on their own.
