Night Stalker is a game created and published by Mattel Electronics for the Intellivision, the Aquarius Home Computer, the Apple ][, and the IBM Personal Computer. An Atari 2600 version of the game called Dark Cavern, featuring somewhat different gameplay, was published around the same time period, and years later a homebrew remake called Dungeon Stalker was created and published for the Atari 7800. In the game, you play a man trapped in a hedgerow maze full of robots, bats, and spiders. You must fetch a gun that has limited ammunition, which fires up to six bullets before it runs out and you must find another gun. You must watch out not only for the robots that fire laser shots at you, but also the bats and spiders, which can immobilize you upon contact.
This game provides examples of:
- Alternate Company Equivalent: To Berzerk, which was at the time ported to the Atari 2600 by Atari.
- Bandit Mook/Blob Monster: The zig-zaggy blobs in the Atari 2600 version, that steal your bullets when you come into contact with them.
- Bottomless Magazines: Purposely averted in all adaptations of this game. In the Intellivision version you get six shots for each gun. In the Atari 2600 version each gun gives you up to 10 shots, which you can accumulate throughout the game, up to 99 shots. Played straight in the Atari 7800 remake, which has a mode that lets you have an unlimited number of shots.
- Difficulty Levels: Four in the Intellivision version.
- Endless Game: You play until you run out of lives.
- Heartbeat Soundtrack: The Intellivision version of the game had a constant heartbeat sound in the background.
- Killer Robot: This game has them. The Intellivision version has different varieties of them.
- Maze Game/Shoot 'em Up: One of those hybrids from the early 1980s.
- The Paralyzer: Bats and spiders.
- Recycled In Space: Dungeon Stalker is basically Night Stalker in a fantasy genre setting, also combining elements of Wizard of Wor, even including the Dragnet theme.
- Scoring Points: For shooting robots, and in the Intellivision version, bats and spiders. In the Atari 7800 remake, you also score points for collecting treasure and shooting the wizard.
