Three soldiers from Science Fiction with suspiciously similar last names are taken from their home universes and placed into an abandoned New York City. They are given an M-16 and 200 rounds of ammunition, and clad in camo fatigues. In order to go home, they must defeat their counterparts. The contestants are Adrian Shephard from Half-Life, John Sheppard from Stargate, and Commander Shepard from Mass Effect. (For fairness, Commander Shepard is a soldier class and is taken from the end of ME1.) Only one Shep is Shep enough to survive. Who out Sheps his fellow Sheps?
