Fallout Online, codenamed Project V13 by Interplay, is an upcoming PC mmorpg being developed by Interplay and Masthead Studios for a 2010/2011 release. The game will be set in the post-apocalyptic world of the Fallout Universe, which also consists of Fallout 1, Fallout 2, Fallout 3, and the as of yet unreleased Fallout New Vegashttp://fallout.wikia.com/wiki/Project_V13_FAQ. Fallout Online will likely receive an ESRB rating of M if it is anything like Fallout 3http://fallout.wikia.com/wiki/Project_V13_FAQ.

Note: Any game claiming to be Fallout Online before the official release is using the Fallout name to gain players, and is not the actual game. Fallen Earth is commonly referred to as Fallout Online, but is unrelated.

Fallout Online will use the same game engine as Earthrise, another game being produced by Masthead Studios, which also happens to be about a post-apocalyptic world http://uk.gamespot.com/news/6207361.html?tag=result;title;0</re>. Fallout Online will likely use the SPECIAL( an acronym for Strength, Perception, Endurance, Charisma, Intelligence, Agility, and Luck, the 7 high level skills that define what you can and can't do) character system<ref>http://fallout.wikia.com/wiki/Project_V13. The Fallout Universe, and more specifically, Fallout 3, made by Bethesda, has put the Fallout Universe at the forefront of post apocalyptic role playing games, and it is likely many players who have enjoyed the series from the beginning or started with Fallout 3 would want to be a part of Fallout Online, giving it a vast, prebuilt fanbasehttp://www.brightsideofnews.com/news/2009/4/6/fallout-online-is-in-the-works.aspx.

Combat is split into unarmed, melee, and ranged weapons, which can be further be split into big guns, such as the fat man, small arms, such as a sniper rifle, and energy weapons, such as the plasma rifle.

• Mods were made for Fallout 3, but will probably not be available for Fallout Online as they would give unfair advantages to some players.
