The Peregrine Falcon Strike Force, the SPARROWS, and the Ikari Warriors are once again on a search for General Morden and his army, this time on a giant island landfill that has been converted into a military fortress, in order to stop his latest coup d'état. After having his newest prototype weapon crushed by the heroes, Morden receives unexpected help when a time portal opens up and high-tech soldiers from the future appear to pledge their support. With their advanced technology, Morden is able to further fortify his base, but the heroes push forward despite the incredible odds

At the very end, the heroes are able to destroy the time portal and cut off the Rebel Army's suppliers. Morden escapes in his rebuilt prototype weapon, now completed and more powerful than before, and confronts them on a giant lake of molten lava. After a long and arduous battle, Morden is defeated and his weapon begins to sink into the lava. The heroes capture Morden and escape via helicopter, but he escapes when the Martians attack the helicopter. The final scene shows the heroes chasing Morden and his men off into the sunset.
