About the Game

Castle Crashers is a side-scrolling brawler that can be played by up to four players cooperatively either locally or over Xbox Live. Players take on the role of knights as they face all sorts of strange creatures in a quest to defeat an evil necromancer and rescue a bunch of googly-eyed princesses.
The game incorporates some RPG elements in that players level up their characters by defeating enemies and earn skill points to be assigned to different attributes. Though primarily focused on melee combat, the player can also choose to use magical abilities.
In addition to weapons and shields, players can also choose to have an animal orb follow them around. Each animal orb offers a different advantage, which can range from earning additional experience points to aiding in attacks.Wikipedia: Castle Crashers
