Gauntlet

Gauntlet is an science-fiction themed arcade game for the TRS-80.

An alien spacecraft has landed in San Francisco, and the aliens within have started an assault on the city. The player must move through the gauntlet, and shoot all of the alien menaces. Progressively more difficult aliens continue to spew from the sides of the maze, and occasionally fire back at the player. The player has a total of 3 lives, and loses one if they come in contact with an alien.
