Dragonborn comes out for PC on February 5, priced at $19.99. It takes place on the island of Solstheim, and pits players against the first Dragonborn, Miraak.
It’s also worth noting that Skyrim, Dawnguard, and Hearthfire are all 50% off at Steam right now.
The PS3 versions Dawnguard, Hearthfire, and Dragonborn are scheudled for release in February, too—though Bethesda had yet to set a specific date.
