Official Expansion to the Game of the Year!
You've taken Azeroth by storm. Now a dark frontier awaits. Beyond the Dark Portal, the sinister agents of the Burning Legion have renewed their demonic crusade to consume the magic of the universe and lay waste to all in their path. From the black horrors of Hellfire Citadel, to the opening of the Dark Portal itself--an infinity of new experiences await.
- Pilot Flying Mounts: Navigate the shattered skies of outland astride netherdragons, wyverns, and other flying mounts. Many of Outland's most remote and dangerous regions are accessible only by air.
- Battle to Level 70: Continue your rise to power all the way to level 70. Then unlock a world of new possibilities, piloting flying mounts, exploring the fabled towers of Karazhan, battling in the Caverns of Time and much, much more.
- Master Two Bold New Races: Whether embracing the mystical energies of the blood elves or unleashing the light-given power of the draenei, new realms of power and possibility await.
- Seize the Dark Frontier: Explore the entire new continent of Outland -- the shattered remains of the once beautiful orc homeworld, Draenor.
