Captain America - The Doom Tube

Captain America in: The Doom Tube of Dr. Megalomann is an action-adventure game and the first video game to feature the Marvel superhero. Set below the Mojave Desert, Dr. Megalomann has built a secret base called the Doom Tube—three concentric cylinders divided into decks and quadrants, connected by an elevator called the "Orbivator". A deadly virus has been released; Captain America must recover password pieces, increase his immunity by collecting Ying-Yang from enemies, and disarm the missiles. He throws his nearly indestructible shield (limited but retrievable), but rotators and lethal beams block progress. The entire game is played in real time with a strict one-hour time limit.
