I don't really like the normal mode with squad vs squad, but they do have an interesting game mode called Horde. In that mode, you fight 50 waves of locust which get increasingly harder to kill. I've only made it to 36 with an extremely cooperative team.
now that sounds very addictive and fun, but I would also like to see a good team multilayer. Its sad it just didn't work out for me in the last game.
