Fallout 4 - Far Harbor is an action-packed subcategory game developed by Bethesda Game Studios. It is a full version game that requires the base game Fallout 4 to play and is only available on the Windows platform. The game is set on the mysterious island of Far Harbor, located off the coast of Maine, where higher levels of radiation have created a more feral world.

In this game, you will search for a young woman and a secret colony of synths, while navigating through the growing conflict between the synths, the Children of Atom, and the local townspeople. Far Harbor features the largest landmass for an add-on that the developers have ever created, filled with new faction quests, settlements, lethal creatures, and dungeons. With new, higher-level armor and weapons, players can become more powerful and make choices that will determine their fate.
