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 a sidescrolling platformer similar to Shinobi. The game is set in the near future, where the player controls a blonde police officer named Duke Oda who, over a series of levels, turns into the cyborg E.S.W.A.T. At first, as a rookie member of the Cyber Police force in the city of Liberty, the player has to clean the streets of an overwhelming crime wave and terminate the most wanted criminals. In the first and second levels of the game, the completely human Duke Oda can only utilize a single shot weapon and can only survive one hit. A second hit will kill him.

The introduction begins with someone logging into a computer, accessing a history archive. Then, it shows a revolution that occurred sometime in the 2080s leading into a series of wars and conflict that lead up to the video game's main setting of the 26th century.
