Have a look at Fallout 4's 'Far Harbor' DLC, out today

The latest and largest downloadable add-on for Bethesda's post-apocalyptic roleplaying games offers new environments and some not-so-friendly faces.

This one's been a long time coming, but we're here: "Far Harbor," Fallout 4's largest DLC to date, is out today on consoles and PC, weaving together narrative threads from the main game and some eldritch, seafaring horror. On a tip from Nick Valentine's detective agency, players travel to the titular island of Far Harbor in search of a missing girl, only to become embroiled in local conflicts involving an atomic bomb-worshipping cult, a colony composed entirely of robots, and quite a few critters who want you very dead.

"Maine has this very rocky, rough terrain and a dramatic coastline," says art director Matt Carofano, in a new reveal post on Bethesda's website. "We thought the rugged setting should inform how the characters are up there. They need to be more survivalist to live in the colder north, with its harsh environment."

In addition to the inhabitants, players will be under threat from exceptionally high levels of radiation -- so you might want to pack a hazmat suit.

Above, you can view the trailer for the DLC; below, you'll find new concept and character art from the developers. "Far Harbor" retails for $24.99 -- a hefty price tag for a DLC, which should go some way in illustrating just how big the thing is.

You can expect a review from us shortly as well, but until then, be sure to check out Rollin Bishop's opinion piece on how Fallout 4's DLC expands the game's world. Oh, and mayhaps something lighter, say a wistful imagining about dating Nick Valentine?
