You lot might have heard about this but in June a game called shadowrun comes out and it is cross platform meaning that PC gamers can play against 360 gamers.

Will be fun for the pc gamers here to play against the console gamers (and probably beat them)

I like the look of this but if you read many reviews, they state that people using keyboard and mouse or xbox controller on the pc or xbox 360 users using the controller show no obvious advantage to either setup. Although I'd like it if they did as the dreamcast did and bring a keyboard and mouse option for the 360.
