Nightmare Fuel / Abadox

  • Despite it being an NES game, the setting of Abadox is gruesome and horrifying, and the developers pulled out all the stops to make the whole experience freaky. The main antagonist is a planet eating Eldritch Abomination that you must go inside in order to rescue Nazar's lover. Along the way, you must fight a variety of creatures, presumably parasites that live inside the alien. The first stage alone pits you against a giant skinless hellhound and a face that stretches its eyeballs at you by its optic nerves. The worst of these is the Cilia Monster; not only it's a really big foe, when you first encounter it, the music is replaced by heartbeats and it pulsates as you descend towards its weakpoint.
