The team responsible for Battalion Wars is hard at work on an expanded version of Xbox Live Arcade hit Geometry Wars: Retro Evolved, but this time it's for Nintendo DS and Wii.

Geometry Wars: Galaxies will, according to Nintendo's official Nintendo Power magazine, be transformed from its arcade-style roots to a more traditional style title with a single-player campaign. The Wii version will make use of motion control and the DS version touch control for gameplay. Both versions of the game will also feature a multiplayer mode, and the magazine says gameplay from Retro Evolved will be included as well.

Galaxies is headed for both platforms this fall. No word on whether the Wii version will make an appearance on the Wii Shop Channel, or in stores.
