Armed with your sacred bow and a miraculously infinite supply of holy arrows, you must fight against the advancing Hordes from Hell for as long as you can.
Move with the d-pad and fire with either the A or B buttons. You can auto-fire by holding a button down. You have 3 lives in total.
The game is split into 2 minute rounds which culminate with a boss fight. When you complete a round your fire power automatically increases.
