Warcraft III: Reign of Chaos (War3 or WC3) is a real-time strategy computer game released by Blizzard Entertainment in July 2002. It is the second sequel to Warcraft: Orcs & Humans, the third game set in the Warcraft Universe.
Warcraft III contains four playable races, including the Humans and Orcs, which had previously appeared in Warcraft: Orcs & Humans and Warcraft II: Tides of Darkness. In addition to these are the Night Elves and Undead, which are new to the Warcraft mythos.
Warcraft III's campaign is laid out similarly to that of StarCraft, being told through all four of the game's races in a progressive manner.
