Night Stalker (1982)

Night Stalker (released as "Dark Cavern" on Atari 2600) is a top-down maze shooter designed by Steve Montero and released for the Intellivision console in 1982. Night Stalker was ported to the Atari 2600 as Dark Cavern and released under Mattel's M Network label. Apple II and IBM PC versions were published in 1983. Robots, bats, and spiders chase you around a maze in Night Stalker, which boasts similar gameplay, if some what slower, to the arcade smash Berzerk. Players must pick up a gun that is randomly placed in the maze. The gun provides the player with a certain number of shots. Once depleted, the gun is again placed in a random part of the maze.
