The Bug Factor: Alien predators invade the Earth! The secret evidence of aliens planning to invade and take over the Earth has been revealed. Since the early 80's, strange unexplained objects have been falling from the sky, landing and remaining unfound until now. Recent laboratory analyses revealed that these objects contain alien gas with the complete genetic codes of an extraterrestrial world: all its fauna and flora. These life pods are destined to xeno-mutate our planet in preparation for the mass landing of the alien invaders. Unbelievably this might very well be the extinction of the human kind and any natural species as we know it! The situation is now critical! Fight against this evil predator menace! The Debuggers and you must defend the future of Earth and its human inhabitants. Choose your character, each Debugger oddly and incongruously equipped with either state-of-the-art or derelict technology, depending on the personality quirks. You will face the enemy head on! Hunt down and annihilate every Alien scum you find! It is a battle to the death. Who will win: Alien Bugs or you?
