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.[1] In each stage, the player can use melee and combination attacks.
