You can get four players on a team as well, not just three. To do this, begin by following the already-listed technique to get three players on a team. Then, during gameplay with all four controllers on, press start on controller three to enter the menu. Turn controllers one and two off. With the third controller, then head to the settings and to controller setup. Slide the fourth controller to the same side as the third. Then go back to the start menu, and just before resuming gameplay, turn controllers one and two back on. Changes will come into effect after the next play.
