The second expansion set, Wrath of the Lich King, was released on November 13, 2008.
The third expansion set, Cataclysm, was released on December 7, 2010.
The original trilogy largely revolves around a soldier by the name of Commander Shepard, whose mission is to save the galaxy from a race of powerful mechanical beings known as the Reapers and their agents, including the first game's antagonist Saren Arterius.
The video game series has since branched into other genres such as tactical role-playing, action role-playing, massively multiplayer online role-playing, racing, third-person shooter, fighting, and rhythm. In Tolkien's works, orcs are a brutish, aggressive, repulsive and generally malevolent species, existing in stark contrast with the benevolent Elvish race (from which their own ancestors may have been developed and corrupted) and generally pressed into the service of an evil power.
An orc or ork /ɔrk/ is a fictional humanoid creature that is part of a fantasy race akin to goblins. Tolkien's concept of orcs has subsequently been adapted and imported into other works of fantasy fiction as well as into fantasy role-playing and strategy games (such as Dungeons & Dragons, Warhammer and Warcraft), broadening the recognition of the creatures in popular culture.
The game was released on November 23, 2004, on the 10th anniversary of the Warcraft franchise.
The first expansion set of the game, The Burning Crusade, was released on January 16, 2007.
While the overall concept of orcs draws on a variety of pre-existing mythology, the main conception of the creatures stems from the fantasy writings of J. Earlier references to creatures etymologically or conceptually similar to orcs can be found in Old English and Anglo-Saxon sources; including Beowulf and 16th-century Italian folk tales, in particular those of Giambattista Basile.
