Castle Crashers

Be a bad-ass.

 

Hack, slash, and smash is the only way to reach the victory.
Castle Crashers is a side-scrolling beat-em-up that incorporates a small number of role-playing video game elements. The game is set in a fictional medieval universe in which a dark wizard steals a mystical gem and captures several princesses. Four knights are charged by the king to rescue the princesses, recover the jewel, and bring the wizard to justice. The game supports cooperative gameplay for up to four players, either locally or online.


Castle Crashers takes the best elements of traditional side-scrolling beat-em-ups and adds lots of flair.
