As Dr. Muto, players forge through 22 vast levels on four distinct planetscapes: from the junkyard world of Totltec, to the half-drowned water world of Aquem, through the smog-choked skies of Flotos, and finally, to the forbidden mines of Mazon. Armed with his newest invention - the Splizz-gun - Dr. Muto morphs himself into a variety of DNA-spliced-up creatures including an alien spider, miniature mouse and hulking gorilla. By morphing, Dr. Muto gains each creature's abilities and physical attributes - such as the ability to cling to webs, squeeze into tight spaces and breathe underwater - all to better crush, outwit and outlast more than a dozen different enemies.
