Capcom may have just released the Xbox 360 game Dead Rising, but the publisher apparently doesn't feel as though it's too early for downloadable content. Now available on Xbox Live Marketplace are eight "keys," which allow access to new costumes that were previously locked. Each of the keys, which include the Man in Black key, the Grandpa key, and the Weekender key are free to download. Dead Rising is rated M for Mature and retails for $59.99.
