"Castle Crashers is a console video game independently developed by The Behemoth. In 2006, Behemoth announced the game as available for download via the Xbox Live Arcade service. It was Arcade's best-selling title of 2008.

Castle Crashers is a side-scrolling, gruesome beat-em-up which incorporates a small number of role-playing game elements. After selecting a character, the player then selects a starting level (beginning with the wizard's attack on the castle) through a graph-like world map; once the player completes a level, they may then opt to start or revisit that level any time. Other levels include shops where the player can buy items for healing, attacking, or defense using coins gained from defeated foes, and arena levels where the player can take on challenges to unlock additional characters, although in co-op the arena turns into a player vs player match, much like the final battle where you fight over a princess."
