About the game
A cartoony 2D beat-em-up adventure for up to four players in co-op, with light RPG progression and a heavy dose of humor. Hack, slash and smash through an absurd medieval world packed with bosses.
Did you know?
The Behemoth hand-animated the game in the style of their earlier hit Alien Hominid, and Castle Crashers became one of the best-selling Xbox Live Arcade titles.

These are not ordinary keys. A gift is usually region-locked and arrives through someone else's account — if the region does not match, the game will not activate. An account means you get someone else's login: the game never becomes yours, and it breaks Steam's rules. A DLC or a bundle is not the base game. That is why none of them count towards the price at the top of the page.
