Retro-2d side scrolling 4 player "Knights of the Round-type" game

CastleCrashers is a fun preview of a game for the consoles (XBOX live?) from the Alien Hominid guys.

I love this kind of game (Capcom's Knights of the Round + Dungeons and Dragons + Sega's Golden Axe).

The trailer (70Mb - swf) is also very cool if they can keep up the flow of imaginative creatures you fight.
