About game

Sans has finally given in to his madness and decided to face Frisk once more, even after his supposed «death». Gaster assists him in this endeavor. This marks the third stage of one of the toughest fights against Sans. Avoid his varied bone assaults. If the battle proves too challenging, try practicing in an easier mode without karma. Your objective is to withstand Sans' attacks and emerge victorious.
