This story comes to us from our good friend KLind. The only reason it is marked rumor is because I don’t have the latest issue of Nintendo Power to confirm.
Screen is from 360 version
The latest Nintendo Power supposedly has a small article on an extension of Bizarre Creations Xbox Live Arcade title Geometry Wars that is coming to the Wii and DS. It is said the developer behind Battalion Wars will be handling the game, which most likely means Kuju Entertainment. Obviously, the Wii version will have motion control, and the DS version will have be controlled via the stylus. The games will include a multiplayer and singpleplayer mode, and include the retro and evolved selections from the 360 version.
