Castle Crashers is a cartoon looking fighting game, like Golden Axe, The Simpsons or Teenage Mutant Ninja Turtles arcade games, set in a medieval universe where a dark wizard steals a mystical gem and captures four princesses. Four knights are charged by the king to rescue the princesses, recover the jewel, and bring the wizard to justice.

This sets up a tongue in cheek romp through side-scrolling levels for four players. The emphasis is on mashing buttons and battering enemies, but the visuals remain cartoony. As you progress you can find new weapons and upgrade your characters. Players work together but also race to pick up the most coins to get the best upgrades.

Castle Crashers Remastered was released for newer consoles with better visuals and smoother frame rates.
