Live Another Life, In Another World: Play any type of character you can imagine, and do whatever you want; the freedom of choice, storytelling, and adventure of The Elder Scrolls comes to life in one legendary experience from all three official add-ons. Dawnguard: The Vampire Lord Harkon has returned to power. By using the Elder Scrolls, he seeks to do the unthinkable – to end the sun itself. Will you join the ancient order of the Dawnguard and stop him? Or will you become a Vampire Lord? Hearthfire: Purchase land and build your own home from the ground up – from a simple one-room cottage to a sprawling compound complete with an armory, alchemy laboratory, and more. Dragonborn: Journey off the coast of Morrowind, to the vast island of Solstheim. Traverse the ash wastes and glacial valleys of this new land as you become more powerful with shouts that bend the will of your enemies and even tame dragons.Go to: http://store.steampowered.com/ and download STEAM client
