1378km is a first-person shooter that immerses players in a historical conflict, allowing them to experience the tension of the Inner German border. The game supports up to 16 players, split between two roles: East Germans attempting to cross the border and East German border guards tasked with stopping them. The gameplay revolves around strategy, teamwork, and quick reflexes, as players navigate the perilous landscape known as the 'death strip' from 1949 to 1990.

Originally scheduled for release on October 3, 2010, to coincide with the anniversary of German reunification, 1378km faced delays due to its controversial subject matter. It was ultimately launched in December 2010 after extensive public discourse. With an age rating of 18+, the game is designed for mature audiences and presents a unique blend of action and historical reflection.
