The name comes from the German word for "one-hander," a reference to the specialized sword. In the game, your fighter is equipped with a single robotic arm that allows you to snatch weapons——directly from destroyed enemy units. This makes the ship a versatile, evolving threat that scavenges to survive. The Mission Structure

: Your primary goal is to destroy "Hyper-Artillery" and strategic infrastructure to pave the way for a full lunar invasion.

: You begin by piercing through Earth's atmosphere, entering highly fortified industrial zones and neon-lit futuristic cities.
