Night Stalker

Night Stalker locked the player in a dark maze with increasingly lethal robots, paralyzing bats and passage-blocking spiders. The gun had only six shots: once empty, you had to run unarmed to the maze center where a new weapon reappeared. Robots evolved: the first was slow and gray, then faster and smarter, up to the white robot firing three bullets at once requiring elaborate strategies to eliminate. Atmosphere was tense — robot footsteps in the dark maze created pure paranoia.
