“Border Patrol” is a serious game, conducted during four weeks in summer term 2015 at the Cologne Game Lab, Cologne, Germany. It’s set in the complex Mexican-American War on Drugs. You may play as the US-Soldier, protecting the border from immigrants approaching from Mexico. Or you play as a Mexican, sneaking across the border into the U.S.A. Do you stop a drug dealer, or do you shoot innocent people, fleeing their miserable life? Can you sneak into the USA, to start a new life? Or do you base your new life on smuggled drugs? And will you experience all eight different endings?
