Alpha One (prototype, 5 lives)

Major Havoc is a vector-based shoot-em-up and platform game in which the evil Vaxxian Empire overran the galaxy many years ago. Most of humanity was enslaved and abducted to the Vaxxian home world, although a few human scientists managed to escape. The Vaxxian Empire has long since collapsed but numerous Vaxxian space stations, all blindly controlled and defended by robots, still remain in the galaxy, mindlessly following their original, pre-programmed orders.

The small band of scientists who initially escaped have cloned the great human hero, 'Major Havoc' and tasked him with flying his 'Catastrofighter' through a wormhole in space so that he may lead a clone army against the dreaded Vaxxian robots and to liberate the remnants of humanity by destroying the enemy reactors. The player controls Major Rex Havoc, the leader of this band of clones.

The game is broken down into two distinct gameplay genres. The first is a shoot-'em-up in which the player controls Major Havoc's spaceship against the numerous robot ships that defend the enemy reactors. The ships are encased in a force-field shield which must first be shot and depleted before the ship itself can be destroyed.
