The first of two downloadable single player expansions for sequel 5 is available today on 360, with a release on expected tomorrow.

Entitled "Lost in Nightmares," the download introduces a new scenario and characters familiar to long-time followers of the franchise. It's already available on for 400 Points, but you can pick it up for 4.99 USD off PlayStation Network on Thursday.

A second episode has been announced for the first week of March - "Desperate Escape" - which will similarly arrive on Xbox 360 March 3 and PS3 March 4.

Both downloads, as well as a number of other extras, will be bundled together when Resident Evil 5: Gold Edition ships March 9.
