On Xbox One Im unable to add more than two controllers when setting up a custom game for local co-op. Ive heard this may be due to hardware limitations and that the One wont support more than two players locally? Can someone confirm? Ive added a ticket and nothing. My kids were devastated that they couldnt play this. We waited ages and feel a bit betrayed to be honest. If only the Xbox Series X supports more than two controllers then I feel lied to. It sucks.
