Showdown in 2100 A.D. is a shooting video game for the Magnavox Odyssey2 that takes the Wild West tradition of gun duels and puts it in a futuristic setting. You and one other player, whether controlled by an AI or by a human, are gunslinging androids that are shooting it out on a field with strange obstacles. To make things interesting, bullets ricochet off of these obstacles, which can either hit an opponent or bounce right back at the shooter.
Here, Darkman425 plays against the computer as fast as possible with a the occasional use of a glitch where a bullet fired from the end of one level carries over to the next level and hits its target without having to fire another time.
