On November 30, 2006, Interplay filed a Form 8-K filing to the SEC regarding a potential Fallout massively multiplayer online game. The Form 8-K contained a prospectus stating that Interplay will be issuing common stock on Euronext to raise capital for developing a Fallout MMORPG. The report stated that the production and launch processes will require an estimated US$75 million in capital. The report also stated that production may start as early as January 2007 and the game may launch as early as July 2010.

In April 2007, SEC filings were made showing the transfer of the IP for the Fallout MMORPG to Fallout 3 developer Bethesda for US$5.75 million. While Bethesda now owns the rights to the Fallout MMORPG IP, clauses in the purchase agreement state allow Interplay to license the rights to the development of the MMORPG, provided that development begins within 24 months of the date of the agreement (which was April 4, 2007), and that Interplay must secure $30 million within that time frame or forfeit its rights to license. Interplay must furthermore launch the MMORPG within four years of the beginning of development, and pay Bethesda 12 percent of sales and subscription fees for the use of the IP.

In April 2008, Interplay announced that the Fallout MMOG had entered production and in April 2009 announced that it would be working with Masthead Studios, a Bulgarian based game developer who are currently working on Earthrise, to assist in the development of the game.

In June 2009, Game Informer reported that Interplay may have lost the Fallout MMORPG rights.

Just a little info, as I can't be bothered to explain.

Please save us from the evils of WoW, and make Fallout into an MMO as well. I would pay to play it on a mass scale in a heartbeat, I know you guys at Bethesda could do it we have faith in you. I have been trying to seek out other multi player games, but the ones I tried didn't hold my interest very long. If it looked like Fallout 3 plus an MMO, the following of players would be massive.

but when there will be a fallout mmorpg,i hope there wont be any monthly cost,like in World of Nerd..eh..gay...eh..warcraft.

there actually is a post apocalyptic MMO coming out that some people say looks alot like fallout. its not actually fallout and its not made by bethesda or anything though. sorry i cant remember its name but theyve talked about it on this show that comes on G4 called the MMO report.

Fallen Earth. I don't ask for a Fallout expansion. An MMO would be odd. No individuality, no lethality, no sense of being unique. Forget it, I am using Fallen Earth. IF interplay doesn't make it the [censored] it.

Second of all, I like the series the way it is. But Beth should seriously balance out the game. Reavers equal god killers. Player equals god. Albine radscorp and every new enemy equal meatfodder. Supermutants equal gore show.

I just want balance and DEPTH to the game, storyline, and everything else.
