"Rendition: Guantanamo" is being developed by the Glasgow-based T-Enterprise for the Xbox 360 and PC platforms.
As revealed in a trailer video, the game depicts the prison in the near future - after its anticipated closing by the U.S. government - as a camp run by mercenaries who detain innocents sold off to their captors to serve as "lab rats" in scientific experiments.
Moazzam Begg, who claims to have been tortured during his near-three-year detention, has been brought on as a consultant to the project, reports the Web site Deadline Scotland.
A Birmingham native who ran an Islamic bookstore, Begg was detained in Pakistan by coalition forces in 2002 and held at Bagram Air Force Base in Afghanistan and, later, Guantanamo. He was released almost three years later without charge.
Begg wrote about his experience in the book "Enemy Combatant: My Imprisonment at Guantanamo, Bagram and Kandahar" (New Press). He has also been interviewed for television and documentaries, including the Academy Award-winning "Taxi to the Dark Side."
In April 2008 Begg was one of eight former Guantanamo detainees who sued the British government, claiming U.K. authorities were complicit in their abductions, detention and interrogations.
T-Enterprise director Zarrar Chishti told Deadline Scotland's Cara Sulieman that Begg helped them with the design of the virtual prison's layout, and that artists created a 3-D rendering of him to appear in the game.
Chishti said the firm has already gotten hate mail from the U.S. demanding that the game not depict the killing of American troops.
"But no U.S. or British soldiers get killed in it; the only ones being killed are mercenaries," he assured Deadline Scotland.
He anticipates strong sales in the Middle East.
Begg said any earnings he gets from the game will be donated to a charity fighting for the rights of detainees.
