Game description

Alien Carnage, starring the hero, Halloween Harry, is an impressive game with no detail overlooked. Professional musical soundtrack, brilliant full-VGA graphics, non-stop animation and huge start-game and end-game cinematics.

If Duke Nukem has a twin separated at birth, it's got to be the character of Halloween Harry! Harry has an armory of weapons he can find and use, besides the devastating flame thrower that he starts the game with. And Harry's jet pack takes him to spots on a level that normal heroes could not reach.

Earth is on the verge of a takeover by aliens intent on turning humans into mindless slave zombies, who can be used in their conquest of the universe. Harry's called into action to Space Station Liberty, and given orders to penetrate the alien ship which has burrowed itself under a high-rise city.

In addition to the flame thrower, Harry can use weapons dispensers he finds during the game, giving him weapons like the photon cannon, guided missiles, grenades, shields, micro nukes, and the very powerful Omega bomb. It's an arsenal that will have the aliens shakin' in their slimy shoes.
