"Fallout 4" is set to release its biggest DLC in a couple of weeks titled "Far Harbor." Prior to the release of this DLC, Bethesda announced a beta version of the game. The beta version is only available to a few selected individuals and they will be given the opportunity to try out the DLC first before its worldwide release on May 19.

Bethesda recently sent emails to those who signed up for the beta version last week that the beta version is already available across all "Fallout 4" gaming platforms PC, PlayStation 4, and Xbox One. The beta access is launched to help developers know how players accept "Far Harbor" and if there are necessary fixes that should be applied.

"Far Harbor" will be "Fallout 4's" third DLC and the biggest one so far. The developer will release more in the coming months but "Far Harbor" serves as the last one from the first batch of DLCs.

The story of "Far Harbor" will revolve on the search of a woman and a secret group of synths. Valentine receives a new case in his agency. Players will then be taken off the coast of Maine in a mysterious island called Far Harbor.

On this island, creatures are feral, brought about by high levels of radiation. The mission is to work hard to bring peace and end the conflict involving the synths, locals in town and the Children of Atom.

It was also announced in the game's official Twitter account that players can only start playing the DLC once they completed the quest titled "Getting a Clue."

As for the size of the DLC, nothing has been confirmed but it's expected to be a huge download. According to SteamDB's listing, "Far Harbor" might have a game size of 3GB for PC. This remains as a speculation but fans will find out once the DLC is available.
