"Sergeant Bryce and Corporal Smith take to the air vents in a bid to avoid the monsters roaming the halls. It seems they're almost home free, until a huge, mutated creature arrives and brings a bloodbath! Meanwhile, Bryce and Smith battle the 'things' lurking in the vents, until they find themselves in the reactor room. Only problem is Dr. Eisler arrives as well and launches Operation Lazarus! In the action packed climax we discover the full scale of the mad doctor's plans, and which of our heroes will survive their terrifying ordeal."

"After rescuing the squad from the crazed Nazi inhabitants Sergeant Bryce, Hillview, and Smith decide there's only one thing for it - they must split up. Hillview is commanded to lead the surviving men to safety while Bryce and Smith head back down to find a radio and call in an air-strike. With any luck they'll wipe the facility with all its monstrous technology from the face of the Earth!"
