This Demo includes 3 scenes for you to get acquainted with the main characters and the overall look and feel of the game.

The Bo-Peep demo allows you to use some of her special abilities and get a feel of the combat system and fighting a few enemies.
The same applies to the Red demo, where you play as Detective Red and get a feel of some of her abilities.
The Co-Op demo is where the game takes you to a whole new level of play, where you get to control both characters and use each of their unique abilities together to pass the scene.
