Miami is the scene for the next big total-conversion mod in Fallout. The mod makers launched the trailer above yesterday, and are seeking volunteers familiar with the Fallout Creation Kit to join the project.

Fallout: Miami’s map is “slightly larger than Far Harbor,” the 2016 premium expansion that took players from Boston up to Maine. “The geographic area covered is roughly from South Pointe Pier to the famed Fontainebleau Hotel.”
