Snake Logan is a top-secret operative for the CIA ordered to complete missions that others would regard as suicidal. One day, Snake is called into headquarters and briefed on a situation that has arisen in Metro City.
It seems that thousands of monster-like creatures are on a rampage of destruction through the city. Many thousands have already died, and Metro has declared martial law just before losing all communications. Right before the city was overrun, authorities received a message from a man calling himself Dr. Mangle. He stated that Metro is to be an example of what will happen to the rest of the world unless all factions of government comply with his wishes.
Snake is ordered to take a plane, fly recon over the city and then return. While circling over the area, he is suddenly attacked by some kind of laser weapon, and the plane loses engine power! He's forced to make an emergency landing and explore the ravaged city on foot. It's now up to Snake - and you! - to save any survivors, find the source of this destruction, and stop Dr. Mangle.
More action - more danger - more Snake Logan! We created a brand new episode for this remastered version, packed with exciting new environments, new music, fresh challenges, deadly enemies, and explosive twists. Get ready to dive ever deeper into the world of BioMenace — the fight is far from over!
