What Is NV:MP (New Vegas Multiplayer)?

Updated

NV:MP is an unofficial, community-made multiplayer framework modification for Fallout: New Vegas (2010). It is not a standalone game and not an official Bethesda product: the project began in 2015 and has been maintained since by a dedicated group of developers, and it is powered by the X:MP framework, which supplies the networking technology that makes retrofitting multiplayer and scripted gameplay possible. If you already own Fallout: New Vegas and want to play it with other people, NV:MP is the relevant project to look at; if you are looking for a commercial multiplayer release or official support, it is not that.

What NV:MP actually is

  • A framework modification, not a game. NV:MP modifies Fallout: New Vegas rather than shipping its own content or executable world. You still need the base game.
  • Community-made and community-maintained. Development started in 2015 and has continued under a dedicated group of developers rather than a studio.
  • Built on X:MP. X:MP provides the networking layer; NV:MP uses it to retrofit multiplayer and scripted gameplay onto the original single-player title.
  • Unofficial in every sense. The site states plainly that NV:MP is not affiliated with Bethesda Softworks, Obsidian Entertainment, or Microsoft.

Who makes it, and is it official?

No — it is an independent, fan-made modification. The project's own legal disclaimer says NV:MP is not affiliated with Bethesda Softworks, Obsidian Entertainment, or Microsoft, and that it is provided "as is," with no express or implied warranty. Fallout and all associated assets remain the intellectual property of Bethesda Softworks.

That has a practical consequence the site also spells out: the team does not resell, redistribute, or charge access to any associated games. In other words, NV:MP is not a way to obtain Fallout: New Vegas — you bring your own copy.

Where to go next

The project's homepage lists the practical entry points: an install page for NV:MP, a Discord, a wiki, an "ATK: Factions and Groups" section, and a contact route for the team. If your goal is to actually get running, start with the install page and the wiki, and use the Discord for current troubleshooting — those are the channels the project itself points to.
