Solvalou

Solvalou is a 1991 first-person rail shooter arcade game developed and published in Japan by Namco. The sixth entry in the Xevious series, the player takes control of the Solvalou starship from a first-person perspective as it must destroy the Xevious forces before they take control of Earth. The Solvalou has two weapon types: an air zapper to destroy air-based enemies, and a blaster bomb to destroy ground-stationed enemies. It runs on the Namco System 21 arcade board.

Solvalou was advertised as a "hyper-entertainment machine" for its sit-down cabinet design and 3D shooting gameplay. The game is named after the starship the player controls in the series. Although it proved to be a commercial failure, Solvalou was well received by critics for its realism, 3D graphics and impressive hardware capabilities, with some finding it to be better than Namco's previous 3D arcade titles. It was digitally re-released for the Japanese Wii Virtual Console in 2009 as one of the first titles under the Virtual Console Arcade brand. A home port for the 3DO Interactive Multiplayer was announced in 1994 but never released.
