Gauntletak

Gauntlet (later Gauntletak) is a multidirectional shooter game written in 1984 by Donald R. Lebeau for the Atari 8-bit family of computers. It was released as shareware, with a full-version available for registration of US$35. Gameplay was divided into separate screens (50 in all) with terrain and enemies (though the game can be played with the last half of the total number of screens and no terrain at all).
