Bethesda has this afternoon announced a brand new Fallout game, called Fallout: New Vegas, planned for release in 2010 for the Xbox 360, PS3 and PC.
Speaking at an even in London, Bethesda's Pete Hines confirmed the game is not a sequel to Fallout 3, describing is as "simply another Fallout game in the universe".
The game is being made in conjunction with Obsidian, maker of classic RPG Neverwinter Knights 2 and the upcoming Alpha Protocol.
A number of people who worked on the original Fallout games are now at Obsidian, including current CEO Feargus Urquhart, previously of Black Isle Studios.
Hines said at the event: "We're working on another Fallout game with Obsidian Entertainment. You may know that there are guys at that company who worked on the original Fallout games, and we have been working on a new Fallout game with them. It's called Fallout: New Vegas, it's scheduled for 360, PS3 and PC at the end of next year, and that is just about all we're going to say about it for now.
"It is not the sequel to Fallout 3. It is simply another Fallout game in the universe. It has no impact whatsoever on what Todd Howard and his guys are working on. This was just a great opportunity, we thought, to work with some guys who know Fallout. Fergus and those guys were there in the early days of Fallout. (It is) a cool opportunity to do something unique with those guys, and something we've really been enjoying working with them on.
"We'll be doing the full reveal when they're ready to show what they've been up to, but that's not quite yet. Perhaps some time later this year."
While Hines was careful not to reveal any details on the game, he did say that it will be "the same sort of experience" as Fallout 3 and, when asked about the game engine, responded with: "We'll get into all the specifics on what exactly we're doing a bit down the road, but you can make your own educated guesses on this."
Speculating, there was a major settlement in Fallout 2 called New Reno, which was based on the real world place. It was a town dominated by four gangster families. Calling the new Fallout game New Vegas suggests it might be something along those lines.
We'll have more as soon as we get it.
