Einhänder

Einhänder is a scrolling shooter developed by Square for the PlayStation console. It was released in Japan on November 20, 1997 and in North America on May 5, 1998. It was also re-released for the Japanese PlayStation Network on June 25, 2008. The name Einhänder is German and denotes a type of sword that is wielded with one hand, here used to refer to the single manipulator arm possessed by the player's spacecraft.
The game is based on the story of Endymion and Selene and set in a fictional future during a war between the Earth and the Moon. The player is part of the Moon's forces and must invade enemy territories to gather reconnaissance and enemy weapons. The music of the game was composed in electro/techno style by Kenichiro Fukui and was published in Japan as a soundtrack album. The game received positive reviews from critics, who praised its gameplay and graphics, but felt the game's short duration and lack of two-player mode were minor flaws.
