History is adding to the pantheon of survival series, this summer debuting Alone, in which 10 survivalists are left in the Vancouver Island wilderness and have to survive using what they’ve been able to stuff into a backpack. At stake is $500,000 awarded to the person who lasts the longest.

The series is in the tradition of Discovery’s Naked and Afraid, and CBS’s Survivor, except these survivalists will have no team, no partner, no producers, no camera crew, no celebrity host, though it appears they will have clothes — or at least a backpack.

Alone also will air as a synchronized global TV event, in more than 200 territories worldwide on History and other channels from the A+E Networks portfolio.

The competitors are separated from one another in harsh terrain to hunt, build shelters and fend off predators. They will face extreme isolation and psychological distress as they plunge into the unknown, and will self-document their experience, History said. Alone is produced for History by Leftfield Pictures.

The network’s slate of reality series currently includes features a roster of hit series including American Pickers,, American Restoration, Ax Me,n, Counting Cars, Pawn Stars, and Swamp People.
