Bethesda has just released the official trailer for the third piece of downloadable content for Fallout 4, Far Harbor, which is scheduled to release on May 19 on Xbox One, PlayStation 4, and PC for $24.99.

Far Harbor will introduce a new case for Valentine’s Detective Agency which will lead the Wasteland’s favorite Vault Dweller, you, on a search for a young woman and a secret colony of synths. Players will travel off the coast of Maine towards the mysterious island of Far Harbor, which has become more feral due to higher levels of radiation.

Bethesda says Far Harbor features the largest landmass for an add-on Bethesda Game Studios has ever created, which is saying a lot considering some of the massive pieces of content it’s created for some of its previous titles, including The Elder Scrolls V: Skyrim. Far Harbor is filled with new faction quests, settlements, dangerous creatures, and dungeons. Luckily, there will also be new higher-level armor and weapons to help you survive this new task.
