The DLC pack will cost $9.99 in North America and £7.99 in the U.K. on its own, and it is included in Fallout 4's season pass. If you didn't purchase the season pass before March 1 and you're still interested in buying it, you'll have to pay the new, higher price of $49.99 instead of the original $29.99 price.
Here's the full description for Automatron from Bethesda; you can watch a trailer above:
In Automatron, the mysterious Mechanist has unleashed a horde of evil robots into the Commonwealth, including the devious Robobrain. 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 such as the all-new lightning chain gun. Even customize their paint schemes and choose their voices!
Automatron is designed for characters that are at level 15 or higher. It will be followed by the "Wasteland Workshop" DLC pack in April and the story-based expansion Far Harbor in May. Bethesda said last month that it will be running closed betas for all three add-ons on all platforms, but did not provide any details today on a beta for Automatron. We've reached out to the publisher for comment, and will update this article with any information we receive.
