With the new online coop, COUCH COOP please!
If you want to get serious (better communication) AND/OR have more fun in online coop multiplayer, you want to be able to play splitscreen with friends. It's a feature any game should have anyway as long as there is no good reason that it shouldnt specific to the particular game. In absolver the contrary is (now) the case. It's also a good way of showing friends the game to help grow the community
