WARNING: This is the scariest thing I have made! Play with caution! Controls Your only means of defense is clicking. One Night with Airhorn will put you in a facility with small rooms. You will move from room to room to room defending over 30 versions of Airhorns! One night takes 20 minutes to complete, I have timed it. Learn the complex lore of ONWA with every death and phone call! Survive one night to win.. good luck... Best played at night in a dark room with the max volume and fullscreen.
