"Fallout Online" (previously known as "Project V13") is a canceled project by Interplay and Masthead Studios to develop a "Fallout"-themed massively multiplayer online game. It entered production in 2008. In 2009, Bethesda filed a lawsuit against Interplay regarding "Project V13," claiming that Interplay has violated their agreement as development has not yet begun on the project. On January 2, 2012, Bethesda and Interplay reached a settlement, the terms of which include the cancellation of "Fallout Online" and transfer of all rights in the franchise to Bethesda. Since then, "Project V13" has been revived as a completely different project called Mayan Apocalypse, unrelated to "Fallout".
