Hi there, my clan has a NFO server for Crysis 3 and I would like to set it up as Cell Vs Rebel Server(No suits) Can anyone point be in the right direction as to what needs to be done. If i just select it from the "easy setup" option it doesn't work at all.

Thank you for your reply will work on this now
