Ahead of its release in November, Bethesda’s post-apocalyptic role-playing game Fallout 4 is now available to preorder for Xbox One through the console itself, Microsoft announced today.

For a limited time, everyone who preorders Fallout 4 through their Xbox One will receive a free copy of Fallout 3 for Xbox 360. A code for the acclaimed 2008 RPG will be delivered to you in 7-10 days.

This promotion was announced back at E3 2015 in June.

Fallout 3 will be playable on Xbox One by way of the console’s new backward compatibility functionality when the feature launches this fall. If you’re an Xbox One Preview Program member, however, you can start playing Fallout 3–and other Xbox 360 titles–on your Xbox One right away.

Fallout 4 launches on November 10 for Xbox One, PlayStation 4, and PC. Recently, Bethesda explained why it has turned down every offer so far to make a Fallout movie.
