Descent (video game)/Nightmare Fuel


 * Remember those bosses which teleport around the arena, often shoot homing projectiles and make an eerie ticking engine sound?
 * In Descent 3, the "Old Scratch" type robots have a dark gray paintjob that blends in extremely well with the game's frequently gloomy environments, and they're quite stealthy aside from a quiet, creepy noise they make occasionally. Hearing that noise in a dark cave tends to result in player panic and frantically looking around for said robot... which has a nasty tendency to then pop up right next to the player and scare the living daylights out of them.
 * Descent II's Diamond Claw did this too, except they didn't make that idle clicking noise. Just silence between the periodic hrumphmm... hrumphmm as it slowly approached the player. By the time you figure out where he i- CLANG! OHMYGOD!!!
