When vicious and brutal aliens arrived at a town on the western frontier, you, as a federal sheriff, were ordered to head there and investigate. With the shadow of night hanging over the small town, you will encounter aliens with advanced technology, as well as their earthling minions equipped with stealth devices. Make good use of these alien devices and your weapons of justice to defeat the aliens and villains, and save the darkness-covered town! Wield controllers to use up to ten types of western firearms and over a dozen interactive items in the game with real actions. Use your expert shooting skills combined with high-tech alien equipment such as laser blades to destroy your enemies hiding in the darkness.
