Castle Crashers is a 2D beat ’em up video game developed by The Behemoth. After selecting a character, the player then selects a starting stage through an overworld map. After completing a stage, the player has the choice to revisit it or to move to another stage. The map also displays shops where the player character can buy items and weapons using coins gained from defeated foes and chests. Arena stages can be unlocked where the player character can take on challenges to unlock additional characters. Castle Crashers supports cooperative gameplay for up to four players, either locally or online. The game progression in terms of what stages are unlocked is defined by the player who is furthest along, although some levels require all players to have unlocked them before proceeding to them; however, each player character will gain experience points and acquire wealth, weapons, and animal orbs independently as they progress with the rest of the party.
