Resident Evil: Degeneration, known in Japan as Biohazard: Degeneration (バイオハザード ディジェネレーション, Baiohazādo Dijenerēshon?), is the first full-length CG animation feature based upon the Resident Evil series of games. It was announced by Capcom and Sony Pictures Entertainment Japan on October 29, 2007.
Unlike the previous Resident Evil film trilogy, Degeneration is set within the same universe as the original video games. The teaser included with the Resident Evil: Extinction DVD and Blu-ray Disc confirmed the appearance of Leon S. Kennedy and Claire Redfield. The film made its premiere in Japan on October 11, 2008 at the Tokyo Game Show, and was released nationwide one week later on October 18. The DVD and Blu-ray releases are slated for December 17, 2008 in Japan and December 27, 2008 in North America.
