Fallout London is a massive mod as extensive as any expansion DLC for the game, built around bringing a whole new area, London, U.K., into Fallout 4. With so much to offer, players are wondering if it’s a free or paid mod.

Snag it while it’s free. Screenshot by Dot Esports via GOG.com Yes, Fallout: London is currently free to play via GOG.com. However, this offer expires on Aug. 1. So be sure to claim your free copy before the first of August, as it’s unclear whether it will become a paid mod after the offer expires.
