A cosmic cloud has shrouded the land in permanent darkness. Red death rains like blood. Monsters from beyond lurk in the shadows, spawning their evil offspring. Fight them with light and fire, find a sanctuary. Survive this unholy night.

The controls guide the player character, and a flashlight that illuminates the ground ahead. Press fire to use the gun. Gunfire will only strike an illuminated spot, or at close point-black range near the player character. If you let the monsters or their firepower hit the player character you will lose a life. A bonus life is awarded for every 10,000 points.
