Warcraft 3 is a real time strategy game developed by Blizzard, Inc. and is the predecessor to the company's World of Warcraft MMO title. Warcraft 3 can be played as a single-player game or against other players via local area network or Battle.net, Blizzard's online game hub. Players can also create custom maps on which to contest multi-player battles.
