Bethesda Softworks has released the fourth video dev diary for Fallout: New Vegas, the next chapter in the Fallout franchise in the works at Obsidian Entertainment. New Vegas is a town of dreamers and desperados being torn apart by warring factions vying for complete control of this desert oasis. It is a place where the right kind of person with the right kind of weaponry can really make a name for themselves, and make more than an enemy or two along the way. As you battle your way across the heat-blasted Mojave Wasteland, the colossal Hoover Dam, and the neon drenched Vegas Strip, you'll be introduced to a colorful cast of characters, power-hungry factions, special weapons, mutated creatures and much more. You can choose sides in the upcoming war or declare "winner takes all" and crown yourself the King of New Vegas in this follow-up to Fallout 3. Fallout: New Vegas is due to be available on October 19th 2010 in North America and October 22nd across Europe, for PC, Xbox 360 and PS3.
