Project V13 is a codename that has been given to two games in development to be published by Interplay Entertainment.
The first incarnation, also called Fallout Online, was to be a massively multiplayer online role-playing game (MMORPG) developed by Interplay Entertainment and Masthead Studios. Among its developers were Chris Taylor and Mark O'Green, two of the creators of the original Fallout.
On January 10, 2012 the game was put on hiatus after a legal dispute which restored the development and publishing rights to Bethesda Softworks.
After a long period where its status was unclear, Interplay and Black Isle Studios announced a new Project V13 on 20 December 2012, this time a strategy based RPG, its development to prototype stage would be funded by a crowdsource campaign.
