The year is 2156AD.
Modern science has revolutionized the criminal underworld.
Cyborgs, robots, mutants, biomonsters...
Criminals use outlawed technology to assert their power.
By the beginning of the 22nd century, the underworld was ruled by the criminal syndicate BUGS, an organisation with
ruthless leadership and vast scientific resources.
Eventually, BUGS' sinister ambitions could not be contained.
Criminal cells all over the world enacted a simultaneous global assault against government and military facilities.
Peace was shattered and anarchy ensued as the world's major cities came under BUGS' control.
Amidst the chaos, a member of the military's secret corps receives an order:
"Infiltrate the BUGS stronghold, take out their leader and crush the insurgency!"
That man's name is Joe. He is a test subject for the supernatural experiments conducted by the government behind closed doors.
Their research has turned him into a "human weapon" with astounding extrasensory abilities.
His power...
Unstoppable punches infused with psionic energy: "PSI Knuckle!"
Every punch sends PSI energy coursing through his body.
PSI Trance, PSI Teleport... a vast array of phenomenal psychic powers, his to command.
Go, Psi Knuckle Joe! Bring justice to the world, one punch at a time!
