Alien Storm (Sega Master System)

Shape-changing alien scum take over your city. Fry the slimy horrors and smash their bid for global conquest. Blast into action with ray guns, flame throwers, power-whips, and more! But watch your step! Harmless objects might transform into vicious aliens. A trash can erupts with spiked tentacles that slash at the helpless! Only quick reflexes and precision weaponry can keep you off the aliens' menu.
