I'm happy LAN play is available. But, I want to play 1v1 instead of 2vX cooperative. If I have the other player in a party, I'm able to try to start a 1v1 game, and my partner is able to accept, but it immediately says there are too many people in my party for that mode of play.
Is cooperative mode the only way to play with people on a local LAN? If not, how do I play 1v1 with a LAN partner?
