"up and running," unlike Fallout 3's urban graveyards.
Vegas "still exists and thrives" despite the global nuclear war. To explore everything on offer could take "hundreds of hours" reveals Hines.
"Unlike the previous Fallouts, where you start in a vault and you are a vault dweller, this one starts with a curveball," Hines tells , reports .
New Vegas takes places some years after the events in Fallout 3 but has no direct connection with that story or any of its characters. Gamers will start in this hostile city in 2280, 200 years after the great nuclear war between the United States and China.
Moving to Las Vegas gives fans "a brand new, fresh experience that has a familiar feel of Fallout, but otherwise it's an entirely new game and a new look, with Joshua trees and tumbleweeds and blue skies," explained Hines.
"Vegas is up and running. It is not a ghost town. It still exists and thrives. There are casinos, and you can go down onto the Strip. It will have a very different feel from that standpoint."
New Vegas is "a self-contained story. You don't have to have played the previous games to have any clue what's going on here." You start off by customising your character.
"You were a courier, and you were obviously carrying something that somebody wanted," Hines says. "Part of the story is finding out what you had and what they took." This is a great departure from the Vault Dweller past that usually starts of a new Fallout game.
Fallout: New Vegas releases on Xbox 360, PS3 and PC this autumn.
