''Castle Crashers is great fun. If you like the classic, simple fun of side-scrolling beat-em-ups, you'll enjoy this game. If you like the frantic hilarity of a cooperative/competitive four-player romp like Gauntlet or Four Swords, you'll enjoy this game. If you like the inimitable, tongue-in-cheek, grin-inducing art and humor of The Behemoth from Alien Hominid or their many Newgrounds titles, you'll like this game. In fact, I wish I could wholeheartedly endorse Castle Crashers as a great buy for nearly any Xbox 360 gamer. Unfortunately, if you like online multiplayer, and were hoping to get in on "this month's only online multiplayer XBLA game" as boasted on Castle Crashers' devblog, I'm going to have to recommend you wait a while before purchasing this one. The Behemoth seems to have gone ahead and released a semi-broken game, whose title couldn't be more unfortunate, given the resulting problems.
It really is a shame, too, because Castle Crashers is delightfully enjoyable. The game, for those who have somehow missed out on the previews for the last two years, is a four-player, arcade-style side-scroller in the vein of classics like the arcade versions of X-Men, Dungeons & Dragons, or The Simpsons - colorful stages filled with busy backgrounds and dozens of enemies, and distinct player-controlled characters with brutal combo-based fighting moves and over-the-top special attacks. Behemoth's typical humor is in full effect in every aspect of the game, from intentionally crude enemies and unusual items to a constant stream of in-game jokes. Enemy guards sit and read magazines while they wait for you to approach, a forest full of animals get the crap scared out of them by a humongous boss, and a river stage can be navigated while floating on the corpse of a fallen baddie.''
