In the distant future, man has advanced into space and spread to worlds throughout the galaxy. On one such planet, Jerra, a brutal war began between the Jerran army and the Nexram - those who opposed a galactic Earth government. To combat the threat the Jerran army created the MDS - Most Dangerous Soldiers - who possess elite fighting abilities. However, one such soldier, MD Geist, was deemed too ferocious and imprisoned inside an orbiting satellite. Now, in the present, both sides have been decimated and the planet lies in ruins. After his satellite falls to the planet, MD Geist wanders the wasteland once more. And after killing the leader of a powerful gang, Geist finds himself in the company of a woman named Vaiya. Together, the two join with survivors of the Jerran army and set forth on a quest to exterminate Death Force - a doomsday device built by the Jerrans - before it activates.
Both MD Geist and Hell Target are sci-fi anime from the 80's. Though they have different plots, both are rather violent and gory and have a somewhat similar feel to me. Neither are that great in my opinion, but if you happen to like one you might like the other.
