Activation in Steam.

Fallout 76 is a new game set in the popular post-apocalyptic world. This time we find ourselves in Vault 76, where a total of 500 inhabitants were placed. The Vault was the first to open after the bombs fell and it is up to you to rebuild the USA.

The game is online only and will offer the option to play alone or with friends, while you will meet other players in the world as residents of Vault 76.

This is the first survival game from the world of Fallout 76, and in terms of story it is a prequel to all the games, so it's kind of like Fallout 0. What's interesting is the ability to build bases alone or with friends, fight monsters, and possibly even find a missile silo and throw a nuke at your evil neighbor :)
