Earth has declared war on Selene, a prosperous moon colony first settled
in the 21st century. Although Earth is still likely to win the war with
its vast resources, Selene has a new hope: Fighter ships by Endymion and
Astraea, known collectively as "Einhander," are being used successfully
to thwart Earth's progress in the war.
The player controls one of three ships: The Endymion FRS Mks. II and
III, as well as the Astraea FGA Mk. I. Each ship can be equipped with
special weapons stolen from enemy ships in battle. Weapons can be
mounted on the top or bottom of the Einhander, and behave differently
depending on the side they're on.
Einhander is at heart a two-dimensional futuristic shooting game,
similar to the Gradius and R-Type series. However, unlike the
traditional shooters, everything in the game is animated in 3D.
