I am trying to set up a LAN party of mw3 with some friends. We have 4 ps3 and 8ppl. The only way to play a 4v4 match among ourselves is to do a online private match since "LAN" doesn't allow split screens. But the problem is that when I create or join a private game with split screen mode. I can only use the 5 default classes even when I abled the custom class option. Does anyone know anything about this?
