It's star year 4045 AD. A period of relative calm exists between the Allies and their mortal enemies, the Archons - but that uneasy truce is shattered with the appearance of the fearsome Nazi-era laboratory project, the Megalodon! Having escaped a barren Planet Earth, the shark-man hybrid seeks revenge for the destruction of it's natural habitat, and aims to slaughter any and all who get in it's way! But, what the Allies don't know is that due to a special DNA trait that can transmute the human race back into reptilian form - the meg is wanted by the Archons. With war suddenly re-ignited, the Allied leader Princess Kali, Van Helsing, and Bigfoot once again prepare to take on General Stalin, Aleister Crowley, and their leagues of bloodthirsty lizard soldiers. Enter Bigfoot vs. Megalodon!
