By using two Joy-Cons, players can tackle the game in its entirety with one player acting as the main player who controls Jason and SOPHIA III, and the second player acting in a support role. The support player can freely move the cursor and use it to provide cover fire for Jason/SOPHIA. Additionally, The support player has a special sub-weapon that only they can use called the Eraser Bomb. This can be used to nullify enemy projectivles and destroy weaker enemies. Whenever you land a shot or use an Eraser Bomb, your special gauge will increase and you can then use part of the gauge to drop recovery items for the main player.
