Bethesda Softworks has finally made official the next massive "Fallout 4" downloadable content, which is called "Nuka World" and was leaked last year.

As its name suggests, "Nuka World" will take place in an amusement park that is all about the favorite soft drink brand in the "Fallout" world. It will be the final DLC to be released for "Fallout 4."

Story-wise, the "Fallout 4" "Nuka World" DLC will be as big as the Far Harbor, which was deemed the largest expansion pack for the action role-playing video game.

Priced at $19.99, "Nuka World" will be released in August and will mark the end of the post-launch content releases for "Fallout 4." The description for the DLC is as follows:

Take a trip to Nuka-World, a vast amusement park now a lawless city of Raiders. Explore an all-new region with an open wasteland and park zones like Safari Adventure, Dry Rock Gulch, Kiddie Kingdom and the Galactic Zone. Nuka-World features new quests, Raiders, weapons, creatures and more. Enjoy the ride!

The "Nuka World" DLC was first discovered by fans who went through the "Fallout 4" game files when Far Harbor was released. The tipsters believe that the amusement park was inspired by the Hershey Park.

With the game files pertaining to the upcoming DLC already there, it looks like "Fallout 4" was already being prepped up for its arrival.

However, before "Fallout 4" "Nuka World" DLC drops, there will be two more expansions to look forward to—the "Contraptions" DLC ($4.99) and the "Vault-Tec Workshop" DLC ($4.99).

Scheduled for June 21, the former should allow players to create new elevators, conveyor belts, sorting machines as well as armor and weapon racks and track kits.

On July, "Fallout 4" players get the "Vault-Tec Workshop" DLC, where players can build their own Vaults the same way the mobile game "Fallout Shelter" works. Enemies will arise as gamers put them together.
