Disney Epic Mickey 2: The Power of Two for PLAYSTATION 3 features 2-player split screen play with Oswald in "drop in/drop out" mode. That means an additional player can drop in at any time during gameplay and control Oswald.
To play Disney Epic Mickey 2: The Power of Two in Co-op mode, the PLAYSTATION 3 system must have at least two (2) synced controllers.
NOTE: Oswald (the second player option) will only be playable after he's been introduced in the game (in Dark Beauty Castle) and after completing the tutorial. Once you've completed the tutorial levels from Yen Sid's Lab with Mickey, mastered the paint brush and found your way to Dark Beauty Castle, an additional player can drop in and play as Oswald as will be indicated on screen.
Playing Disney Epic Mickey 2: The Power of Two in Multiplayer mode:
1. During gameplay, when Oswald is present, simply press the Start Button on the additional synced game controller.
2. To return to single player mode, press the Start Button again.
