with company.

Features
Twelve systems, synchronised
Shared world and weather, server-held inventories, doors and containers everyone agrees on, NPCs the server walks, positional voice. Written against what the mod actually does today.

The server is a TypeScript runtime
Events, players, world state, objects, voice and chat, all exposed to resources you drop in a folder. The full reference is generated straight from the server.

Two hundred years later
The road out of Sanctuary is wide enough for everyone
Fallout 4 shipped a Commonwealth built for one survivor. Fallout MP hands the same road to your whole group and lets the wasteland sort out the rest.

The Commonwealth, with company
Screenshots are from Fallout 4 itself. They show the world Fallout MP runs on.
Bring someone who watches your back
Every player carries their own inventory, gear and condition. Trade ammo, split a stimpak, or leave someone behind in the dust - the Commonwealth does not care either way.
Hold somewhere together
Doors, locks and containers are the server’s to decide, so a place can be shut, opened and stocked for everyone at once. What one player leaves in a footlocker is what the next one finds.
Somewhere to come back to
Servers can host the fortified towns the wasteland grew around. Trade, argue, take a contract, and head back out before dark.
The vault door is open
