With the release of both of Fallout 4’s new downloadable content, Contraptions and Vault Tech workshops, all that’s left of the game’s previously-announced expansions is a trip down to Nuka World. While we know the expansion will release some time this month, Bethesda has yet to disclose exactly when we can expect to make a trip down to everyone’s favorite post-apocalyptic theme park. But today, we’re learning Nuka World may be a larger expansion than Far Harbor.

According to the SteamDB entry for Fallout 4’s Nuka World, the expansion is expected to weigh in at 3.66GB. That’s quite a sizeable difference when compared to Far Harbor’s 2.69GB, which was Bethesda’s largest expansion it’s created to date.

While Nuka World’s size may indicate it’s larger than Far Harbor, we have a feeling its size is a result of a lot of new content. For example, there are screenshots of Nuka World where a Nuka Cola mascot can be seen, large structures, vendors and more. Real-world theme parks are large when traveling by foot, but they’re also dense in the type of attractions it offers. We feel this will also be the case in Nuka World.
