Skyrim also reduced to half the price.
The Elder Scrolls V: Skyrim – Dawnguard is now available to buy on Steam, Bethesda has announced.
Priced £13.99, the first Skyrim expansion can be yours simply by heading over to Steam.
The pack promises over 20 hours of content including new weapons, abilities, quests and, if you choose, the chance to become a vampire lord.
Those without Skyrim can also pick this up for the reduced price of £17.49.
Dawnguard released for Xbox 360 on June 26, earning a slightly disappointing 7/10.
