Perk-a-Cola Machines

August 23, 2011: Germany
After the 'Rezurrection' DLC of Call of Duty: Black Ops came out, a group of teens began showing unusal abilites such as increased durability, enhanced hand-eye coordination, recovery from blows that would render a man unconscious, and enhanced speed. Sending Agent Lattimer and Consultant Nola to the reports, they found that the teens had found actual working replicas of the Perk-a-Cola Machines from the Nazi Zombies mode.

Later, as more Perk-a-Cola machines were added to the game, more machines came online and more people began finding the machines, releasing Element 115 (Unumpentium, not the element that brings the dead to life). Every time a new perk came out, Lattimer and Nola would go out to pick the machine up.

Warehouse 13.5 (Alt Timeline)
The night before the five AWOL agents planned to break into Global Dynamics to have a second chance at the Halifax Incident, Nola pulled a small cooler out with several bottles of Perk-a-Colas revealing that she and Pete managed to stash most of the machines in the basement of the flower shop.

Today: Warehouse 13
Recently, Nola and Lattimer went to Calico, California (thought to be basis for Buried) in search of newest machine. Otherwise, the machines, while listed in the Video Game Coridoor, are placed along the sides of the Sparring Arena for the fighters and specators to raise a bit of extra money.
