You signed 13 days challenge pact saying that you are the chosen one for surviving in hell. Now you must stand to your own word. Do your best to survive attacks of the lost souls. Beware, they will cut your head off if you don't blow them off first. Use YOUR MOUSE to aim and fire. Use the red dot to determine the perfect moment to fire. Use 1 to 5 NUMBER KEYS or the MOUSEWHEEL to select a weapon. Press SPACEBAR or "R" KEY to reload. Good luck!
