How Long Does It Take to Watch Schwarzes Marken?

The year is 1983. The Cold War is in full effect, and humanity is under attack. Strange aliens, given the name "BETA," have descended to Earth and have been destroying all life. Soldiers have been tasked with piloting large combat suits called Tactical Surface Fighters (TSF) to repel the alien invaders, but the front line is slowly being pushed back towards the surviving cities.

Schwarzesmarken follows the story of Theodor Eberbach and the other members of the 666th TSF Squadron Schwarzesmarken (Black Marks), a ruthless unit that values a mission's completion over human life. Stationed in East Germany on the Oder-Neisse line and led by war hero Captain Irisdina Bernhard, the unit specializes in counterassault attacks on laser-class BETA. But the 666th Squadron finds itself with more enemies than just the alien forces when optimistic rookie Katia Waldheim joins the squadron, drawing the attention of East Germany's secret police, the Stasi.
