The Year: 2242. You're the toughest bounty hunter in the galaxy. You've amassed a fortune by defeating the most vicious creatures known to man. And now, deep inside the enemy Cyborg Fortress, you can almost taste your next paycheck. But there's a little work to be done before you cash in. Like blasting swarms of deadly Cyborgs with your powerful psycho gun. And a battle-to-the-death showdown with Vipron, the vile Cyborg leader. Prepare yourself for one explosive payday!

The game is set in 2877, 800 years after the world's peacekeeping unions have collapsed. They are replaced with World Silent Security Service, a global world order to maintain the security on earth and in space. However, over time the role of the order is questioned, and the Reformist Faction rebel group sends three pilots in Laocorn assault robots to the WSSS' space station Daedalus in earth's orbit. Two are immediately destroyed, but the player gets to control the remaining robot.
