The game is a sidescrolling beat-em-up in which up to 4 players can play, online or locally. Playing as one of the available knights or an unlockable character, players must defeat enemies to progress using attacks and magic. As enemies are defeated, the characters level up, giving access to new combos and abilities. There are also weapons that can be found and used, as well as animal orbs that assist the players in various ways, such as scouting for items. At the end of a boss battle, players then fight each other in a battle to earn a kiss from the rescued princess.
Other modes include Arena, where players fight each other, and a mini-game called All You Can Quaff
Castle Crashers will cost 1200 MS Points
