Re: Online 2 Player Splitscreen
If you are playing on XBox or PS4 you can launch Split Screen play; PC does not have this option.
To do so you'll both need to have PSN/Live accounts; the player who launches the game will be the Group leader and will need to initiate the Split Screen play by visiting the stacked television sets found to the right of the changing booth in either base.
The second player will need to select their account and the Split Screen version of the game will launch. The second player will be unable to interact with anything in the Backyard like chests or customization areas and the Solo Quests will be unavailable.
The first player, as Group leader and the owner of the Backyard will still be able to interact with everything and ultimately controls what game modes everyone plays.
