The game is nearly unplayable because of the top-and-bottom narrow slit view splitscreen. There just is no way to get side-by-side splitscreen, and the entire reason I bought the game was for couch co-op play. I’ve played all the other Borderlands, they all had big, wide, side-by-side coop splitscreen. I can’t read anything, it makes me and my partner motion sick, and it’s like looking through a thin letter-slot. It’s awful! How can this be fixed, how can we get the proper side-by-side view for coop?
At this point there is no vertical split mode. I feel your pain, so we’re just putting the game on the shelf until they patch it in. =(
