It sounds like he wants to play COD MW2 as mutiplayer between pc and ps3
Thats what im thinking as well.
Is there a way to somehow connect the ps3 to my computer?
Cause i have Modern Warfare 2 to the ps3 but my friends have it for computer. So please help
As xtc28 said, it's not possible for a PC game and a game console game (like ps3) to connect to 1 another. Controls are different and probably the features are different between the 2.
If you want to play with/against your friend, you need to get the PC game or your friend will need to get PS3 game.
