Geometry Wars: Galaxies is a multidirectional shooter video game developed by Bizarre Creations and Kuju Entertainment, and published by Vivendi Games for the Wii and Nintendo DS in November 2007. As the first Geometry Wars game to be released on non-Microsoft platforms, Galaxies is a spin-off of Geometry Wars, which was originally included as a bonus game within Project Gotham Racing 2 on Microsoft's Xbox console. This updated version includes a single-player campaign mode, several multiplayer modes, Geometry Wars: Retro Evolved (previously released on the Xbox Live Arcade online service), and support for online leaderboards. The Wii version supports widescreen and 480p progressive scan display.
The soundtrack was composed by Chris Chudley from Audioantics who created the music for all of the Geometry Wars series.
