Headhunter Redemption is the sequel to the Dreamcast and PlayStation 2 game Headhunter.
Set 20 years after the Bloody Mary Virus (released in the Original Headhunter), Jack and His New Partner Leeza X find out something is amiss when they try to stop Weapon Smugglers. The pair must face opposition from the Glass Skyscrapers filled and media controlled 'Above' and The Dregs & Criminal Infested colonies of 'Below.' Jack and Leeza must also face their fears as they try to redeem a world from chaos, especially Jack, whose son was taken away by forces from 'Below,' but might still be alive.
