The ultimate toy: The Cosmic Control Rod. It's in the hands of a nameless fiend who is understandably reluctant to give it back.
If that isn't enough, consider this: a portal has been opened into the Negative Zone, the anti-matter universe that borders on our own. BLASTAAR wants the Cosmic Control Rod for his very own, and has a massive armada poised to invade Earth from the Zone. Only one thing, a S.H.I.E.L.D. nuclear warhead, can close the gateway. Can the player characters halt the invasion from behind the stars and defear Blastaar's forces before they invade Earth? Will they find the Cosmic Control Rod and prevent a war that could annihilate two universes before it's too late?
