Sky Sentinel's arc cannon is severely damaged and on the verge melting down. The crew is stranded off the coast of South America, but there isn't time to stop for repairs. The team must respond to a distress call from none other than Defender-X. Gorghadra is back in Chicago and he is proving to be more than even defender-X can handle. Sky Semtinel's crew must risk every thing in order to destroy Gorghadra! Monsterpocalypse is based on the action-packed, collectible miniatures game from Privateer Press.
