Bethesda Softworks have outlined their downloadable content plans for their best-selling post apocalyptic open-world RPG, Fallout 4.

The publisher plans on releasing three separate add-on packs for the title starting with Automatron which is set for release this March for $9.99.

"The mysterious Mechanist has unleashed a horde of evil robots into the Commonwealth, including the devious Robobrain," reads the expansion's official synopsis. "Hunt them down and harvest their parts to build and mod your own custom robot companions. Choose from hundreds of mods; mixing limbs, armor, abilities, and weapons like the all-new lightning chain gun. Even customize their paint schemes and choose their voices!"

Following Automatron is Wasteland Workshop a smaller DLC package that will allow players to capture various creatures from around the world of Fallout 4 and raise them to battle against each other. Retailing for $4.99, Wasteland Workshop "also includes a suite of new design options for your settlements like nixie tube lighting, letter kits, taxidermy, and more!

Lastly in May, the title's biggest planned expansion, Far Harbor will be released taking players on a story-driven adventure in a new location. "A new case from Valentine's Detective Agency leads you on a search for a young woman and a secret colony of synths," the description notes.

"Travel off the coast of Maine to the mysterious island of Far Harbor, where higher levels of radiation have created a more feral world. Navigate through the growing conflict between the synths, the Children of Atom, and the local townspeople," it continues. "Far Harbor features the largest landmass for an add-on that we've ever created, filled with new faction quests, settlements, lethal creatures and dungeons. Become more powerful with new, higher-level armor and weapons."

Bethesda also confirmed that all three DLC packs will become available to those who purchased the season pass at its original price of $29.99. Starting March 1, the same season pass will go up in price to $49.99 due to the developer adding in more content.

More add-ons will continue to be developed for Fallout 4 including more free updates that improve the title's gameplay and graphics.
