In Warcraft 3, players control small armies of units of a specific race and are tasked with various objectives based on scenario to achieve victory. The common available to play races are Night elf, Human, Undead, and Orc which all have their own unique units. Armies are comprised of 1-3 primary hero units with special abilities, and anywhere from 1-80 additional units to combat other monsters or units. The primary goal of each Warcraft 3 game is to destroy your opponent's base and units with your own units, rendering them unable to fight back. Warcraft 3 features both a single player campaign and online multiplayer gameplay, which includes custom user-made arcade games that use assets from the base game.
