Einhänder is a futuristic, side-scrolling shooter where you pilot a one-man fighter in a war between Earth and the Moon colony, Selene. Gameplay centers on intense, fast-paced aerial combat featuring explosive visuals and a driving techno soundtrack. Its core mechanic is the unique Arm System, allowing you to independently position a weapon module for versatile attack and defense angles, alongside grabbing defeated enemy parts. Expect a challenging, arcade-style experience focused on precision and mastering adaptable weapon loadouts.
The narrative unfolds in a dystopian future following the devastating "First Moon War," which resulted in the collapse of Earth's surface and the rise of a totalitarian regime. The conflict reignites with the "Second Moon War," as the Moon colony, Selene, attacks Earth again, primarily seeking natural resources. You take on the role of a pilot commanding a specialized, one-man fighter spacecraft known as an Einhänder. Your missions involve high-risk incursions into the Earth's capital city.
Throughout the campaign, mission directives are relayed via the Selenean military satellite, Hyperion, and synthesized by the onboard central computer, EOS. The storyline concludes with a significant narrative turn where, upon mission completion, the pilot is designated as the final test subject for the latest unmanned fighter pattern—a mandated sacrifice for the war effort.
As a dedicated shooter, the primary gameplay loop centers on navigating complex, scrolling stages while engaging in relentless combat against enemy forces and confronting large-scale boss encounters. The game demands precision flying and pattern recognition to survive the intense barrages.
The defining mechanical feature is the Arm System. Unlike traditional shooters where weapons are fixed, you control a primary weapon module attached to your fighter that operates independently. This arm can be dynamically positioned above, below, or directly in front of the craft, allowing for highly versatile attack angles and defensive blocking capabilities. Furthermore, this arm can be used to physically grab defeated enemy components or power-ups, adding a layer of tactical resource management to the high-speed action.
Players can also cycle through several distinct weapon types, each offering unique firing patterns and strengths, requiring adaptation based on the specific stage layout and enemy composition.
This title is presented as a complete, standalone main game experience. There are no officially documented downloadable content packs, expansions, or subsequent remasters associated with this core release.
Players can expect a challenging, arcade-style experience that heavily emphasizes mastering the unique physics and positioning required by the Arm System. The atmosphere remains dark and intense, driven by the high-stakes military conflict and supported by its signature electronic music score.
