thx to stevethenarwhal for the engine undertale = toby fox! song=dark,darker,yet darker. this fight after the sans fight in the genocide play through of undertale. as you walk through the door to see Chara and get your "ending". you are surprised to see a strange monster in stead whom attacks you. UPDATE:there is now an "ending" UPDATE 2:there is now a "surprise" after gaster reaches half hp!
