Sackboy: A Big Adventure features a co-op mode with up to three other players by your side, and if you want to see everything the game has to offer, you’ll want to take advantage.
Every level in the game can be played in co-op, and several of the Trophies have multiplayer requirements, so even just for curiosity, it’s worth checking out. More than that though, most worlds have a couple of levels which must be played in co-op.
These levels aren’t part of the main story path, so you don’t need to play them to reach the ending, but they do give out Dreamer Orbs so are very useful when it comes to clearing the Uproar at the end of each world.
Sackboy will have online co-op, but it’s not currently part of the game. For now, only couch co-op is available. You’ll need to push start on every controller playing, then once player one moves to a level, all the players will get to choose their costume (check out our How To Change Costumes guide for more info on customization), then begin the level in co-op mode.
