Today Blizzard Entertainment officially announced the rumored Cataclysm expansion to World of Warcraft. The new expansion adds two new playable races, raises the level cap, and adds a slew of new content to experience.

Instead of adding an entirely new continent or world, Cataclysm fleshes out Azeroth and allows you to travel to the previously inaccessible bits of the map. Here is the full list of features from the press release:

• Two New Playable Races: Adventure as the cursed worgen with the Alliance or the resourceful goblins with the Horde.
• Increased Level Cap: Advance to level 85 and earn new abilities, tap into new talents, and progress through the path system, a new way for players to customize characters.
• Classic Zones Remade: Quest to level 60 as you never have before. Familiar zones across the original continents of Kalimdor and the Eastern Kingdoms have been reforged by the cataclysm and updated with new quests and content.
• Flying Mounts in Azeroth: Explore Kalimdor and the Eastern Kingdoms from a whole new perspective.
• Guild Advancement: Progress as a guild to earn guild levels and guild achievements.
• New High-Level Content: Explore newly opened parts of the world, including Uldum, Grim Batol, and the great sunken city of Vashj'ir beneath the sea, and enjoy even more high-level raid content than in previous expansions.
• New PvP Zone & Rated Battlegrounds: Take on PvP objectives and daily quests on Tol Barad Island, a new Wintergrasp-like zone, and wage war in all-new rated Battlegrounds.
• Archaeology: Master a new secondary profession to unearth valuable artifacts and earn unique rewards.
• New Race and Class Combinations: Explore Azeroth as a gnome priest, blood elf warrior, or one of the other never-before-available race and class combinations.
