Gamasutra is reporting that Bethesda Softworks has acquired rights to the post-apocalyptic Fallout series from Interplay, news based on an SEC filing spotted by No Mutants Allowed. Bethesda had already licensed the Fallout rights for their upcoming Fallout 3, and in an unusual twist, the deal includes a license for Interplay to go forward with their planned Fallout MMOG, but stipulates that development must commence within two years, the game must launch within six years, and the project must have secured financing of no less that $30 million. Failure to meet any of these conditions will result in Interplay forfeiting these rights.
