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.

Since 1973, an invasion of aliens known as BETA upon Earth is driving human civilization into nearly collapse. Facing an enormous mass of enemy force, mankind has developed large humanoid arms called as Tactical Surface Fighters and deployed them to its defense lines through out the world. However, all those efforts could slow down defeats but could not stop BETA, and mankind is forced to abandon major area of the Eurasian Continent. For 30 years, mankind is bogged down in an endless war against BETA without any hopes of victory. 
In 2001, the Imperial Japan faces difficulties in the development of a next-generation main Tactical Surface Fighters (TSF) as it defends the front lines of the Far East. The UN has proposed a joint development program between the Imperial Japan and the United States as a part of its international mutual development project of TSF, the Prominence Project. 
Yui Takamura, a surface pilot of the Imperial Royal Guards of Japan, is given responsibility for the project and sets off to Alaska. Meanwhile, Yuya Bridges, also a surface pilot of the US Army, was heading to the same destination. 
Yet they never knew that their encounter would change their destiny drastically. 
This story with exciting human dramas and robot actions takes place in the development of a new Tactical Surface Fighters, the most important and effective weapons against BETA, at a crisis of human extinction.
