Fallout 4‘s next DLC pack, Vault-Tec Workshop, will launch on July 26.

Bethesda made the announcement today on Twitter, just a few hours before a livestream dedicated to the content is scheduled to begin. It starts at 1 PM PT / 4 PM ET and can be seen on Bethesda’s official Twitch channel.

Vault-Tec Workshop is priced at $5. It allows players to create a “massive” vault and outfit it with a number of new items. Players can also conduct experiments on dwellers.

Here is the expansion’s official description:

“Build a brighter future underground with the all-new Vault-Tec Workshop. Create a massive vault and attract new dwellers using pre-war industrial kits complete with retro-nostalgic furniture, lighting, and art. And like every good Overseer, run Vault-Tec approved experiments on your dwellers to learn what makes an ideal citizen. Vault-Tec has given you the tools, the rest is up to you!”

It wasn’t confirmed, but Vault-Tec Workshop will presumably launch on July 26 across all platforms: PlayStation 4, Xbox One, and PC.

Following Vault-Tec Workshop will be the substantial-sounding Nuka-World, which is Fallout 4’s last expansion.
