Fallout Online project started with a major problem. In 2009, Bethesda, the current owners of the I.P., filed a lawsuit against Interplay regarding Project V13 (also know as Fallout Online), for the rights of the series. After a big novel, Bethesda dropped their injunction in April 2010 and Fallout Online is still coming by Interplay.
Now that you know about this novel, Fallout Online development is running really well, as Interplay Entertainment released their first newsletter this week, explaining how to register on the official website for additional newsletters and a beta-tester subscription:
Mutants and non-mutants who registered at the FALLOUT® ONLINE site are starting to receive tales from the wastelands. Interested players who sign up are on the fast-track for beta-testing and get the added bonus of a free subscription to the pre-release electronic newsletter. (No additional flora will be harmed by the production of this newsletter.) Subscribers may end their participation at any time, again without cost or additional fees. We are just that kind and giving.
Interplay’s FALLOUT® ONLINE is a massively multiplayer RPG set in the award-winning and best-selling FALLOUT® universe. Player characters roam the desert wastes, the radiation-blasted mountain tops, and the mutated forests of the post-apocalyptic world – a land where decisions have consequences and there are multiple solutions to every challenge. Players can decide to participate in the rebuilding of this broken land, seek the adrenaline pumping pleasure of conquest and destruction, or just go launch anvils and ride the merry-go-round.
The registration site is available at http://www.fallout-on-line.com. Register today. Registered players are winners. 
 In a very metaphysical way. Registration does not, by itself, actually win anything. It may earn a meager amount of our respect and affection, but results may vary.
Good luck for everyone who wants to participate in the beta!
