The Earth has been ravaged by a devastating invasion by an alien race named the Vulkil.
Your story begins in the year 2172 as an unidentified Specialist on Olympia Prime, a base located on Earth's moon.
You've just been volunteered to participate in a secret military experimental procedure called ZOA Protocol.
Little is known about ZOA Protocol except that most who undergo it don't survive.
Those who survive experience enhanced abilities such as strength, endurance, speed and dexterity.
As a ZOA Protocol survivor you must use your newly discovered powers to race against time to defeat the Vulkil, ultimately saving Earth.
The game story will unfold chapter by chapter and saving Earth will require you to commandeer space craft, locate and fly to Alien planets & forge or break alliances in the search for a way to defeat the Vulkil.
