From GameBrew - a wiki dedicated to Video Game Homebrew.
This is a port of NightStalker, an action shooting game from the Intellivision console.
You control a man trapped in a hedgerow maze with no exits and many threats, some natural such as bats and spiders, others artificial in nature and much more deadly.
You start out in a bunker in the middle of the map, equipped with a handgun loaded with 6 bullets. When the character needs to reload, a gun icon flashes at 1 of 5 random locations and you will have to traverse the maze defenseless until a new weapon is obtained.
For now, the only enemy is a robot.
