There is a major shoot-out in the west with space cowboys trying to survive monsters. Shoot them and upgrade weapons in this action game. Besides amazing abilities that could easily allow them to escape this trap, there is always the opportunity of using special items. Aid kits can be used or dropped, respectively with E and Q keys. Reload the gun with R key, shoot and aim with the Mouse when the shop is already available. Move with either the WASD or the alternative ZQSD keys. Space-bar is useful when mines should be placed to remove as many creatures as possible.
