The debut release of MouseBall for Unreal Tournament is now available (brought to us by none other than Joey "FrogStomper" Fortuna, for old QuakeCast fans). The page doesn't offer much info, so I beat a description of the mod out of FrogStomper, so here goes: "Team play game. Pits mouse against mouse. Several goals scattered throughout the field and several balls. Kick the balls into the goals that correspond to your color. Prevent other mice from scoring by pushing them. Cheese powerups add speed to your mouse, wings to your balls, and punch to your pushes. MouseFans throughout the stadium cheer you on and jeer at your competitors (depending on how you interpret their Shopping-Mall-Elf-Robot movements)."
