Game description

If Commander Keen: Invasion of the Vorticons was big, then Keen 4 was twice as big. Taking on from the popular Commander Keen concept, the graphics quadrupled in quality using the new angular platforms. With more monsters, more puzzles, more bonus items and new secret passageways... along with Billy's famous pogo stick... you'll be playing for hours!
