Deep below a Southwestern desert, wealthy mogul and super-villain LEX LUTHOR constructs a top-secret device to destroy his top enemy, SUPERMAN. Unfortunately, radiation from the KRYPTONITE-powered weapon has leaked into the surrounding soils and turned scorpions, snakes, and other arid animals into super species! To stop the fearsome fallout, the MAN OF STEEL must travel into the kryptonite caverns, face his worst enemy, and overcome his greatest weakness!
