Cosmic Walker is a cancelled adventure / action game that was in development for the Wii. At Nintendo Fall Conference 2008 the manufacturer shared a movie reel full of upcoming Wii games that were in development, like Punch Out Wii, Sin & Punishment 2 and Another Code R. Another game shown for the first time was a curious space simulation developed by Gaia, the studio created by former Atlus employee Kouji Okada, but no info was shared about it.
In the Supplementary Information documents released by Nintendo from January 2010 onward the title disappeared from the list of the upcoming games aimed for the japanese market and in October 2010 a news spread that Gaia official site ceased activity thus we can conclude that the project was likely quietly terminated by the publisher.
U64 is an archive with articles, screens and videos for cancelled, beta & unseen videogames. Every change & cut creates a different gaming experience: we would like to save some documents about this evolution for curiosity, historic and artistic preservation.
