I was hoping someone could help me with this issue, me and my roommate both have totally legit copies of Crysis 2, but when we join eachothers game it kicks the one person playing out and lets the other in. Is there anyway to fix this?

FIXED: If you want to have multiple pc gamers running off of one internet connection you need to create an autoexec.cfg in the main directory using: net_lobby_gamespy_online_port "64100"

In the number value just change the port value to a different number such as 64101 instead.

Thank god I got lucky and found that command in console command list. =D
