Bethesda's marketing director Pete Hines confirmed on Twitter that the first major DLC for Fallout 4, Far Harbor, will be larger than Oblivion's Shivering Isles DLC. A sizable expansion at the time offering roughly a quarter of the real estate of Cyrodiil in the main game.
The news is promising as Automatron the game's first DLC has proven to contain more content than the price tag would have you to believe.
Far Harbor is due to release in May and will be priced at £19.99, but it is also part of the season pass (£39.99).
