ok, i might get vegas for ps3, but i have a few questions for anyone who might own the game.. 1. Does the game include voice chat for online multiplayer? I hope i didnt buy a $40 headset for nothing.... 2. Is the game hard if u are new to the Rainbow Six series? 3. Is it possible to have a friend sitting right by me on the couch, and play online coop with him? thanks to anyone who helps.
