Heads-up for those that may still be contemplating purchasing the Fallout 4 season pass: the price goes up from $30/£24.99 to $50/£39.99 on March 1 (tomorrow), so if you want it for the cheaper price you'll have to get it today.

As previously announced, the price increase is a result of Bethesda's "expanded DLC plan." The studio has said it will now deliver "more than $60 worth of new Fallout adventures and features" in 2016.

The first three Fallout 4 expansions are Automatron (March; $10), Wasteland Workshop (April; $5), and Far Harbor (May; $25). On top of these these paid expansions, Bethesda has promised to support Fallout 4 with more free updates.

In Automatron a character called the Mechanist releases a "horde of evil robots" into post-apocalyptic Boston, one of which is the "devious Robobrain." Players will have to track them down and use their parts to build their own robot.

"Choose from hundreds of mods; mixing limbs, armor, abilities, and weapons like the all-new lightning chain gun," Bethesda said. "Even customize their paint schemes and choose their voices."

Wasteland Workshop, meanwhile, lets players "design and set cages to capture live creatures--from raiders to Deathclaws," then "tame them or have them face off in battle, even against your fellow settlers. The Wasteland Workshop also includes a suite of new design options for your settlements like nixi tube lighting, letter kits, taxidermy, and more."

Far Harbor is the most expensive of the three, priced at $25. In it, you take on a mission from the Valentine's Detective Agency to find a young woman and a secret colony of synths.

"Travel off the coast of Maine to the mysterious island of Far Harbor, where higher levels of radiation have created a more feral world," Bethesda explained.

"Navigate through the growing conflict between the synths, the Children of Atom, and the local townspeople. Will you work towards bringing peace to Far Harbor, and at what cost? 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. The choices are all yours."

In other Fallout 4 news, Bethesda has announced official mod support will be rolled out after the first DLC is released in March.
