After more than five years in development, Fallout: New California, a total conversion mod for Fallout: New Vegas, will launch on Oct. 23 (for Windows PC, of course), the mod’s makers announced yesterday.

New California’s development team observed the project’s fifth anniversary on June 1 (though some work had begun before then) with a new trailer yesterday. Their mod is a prequel story to Obsidian’s Fallout: New Vegas from 2010. The player character begins in Vault 18 inside ruined Los Angeles, as an adopted resident there.
