It's been more than a decade since the last proper Warcraft game—by which we mean an offline real-time strategy game, not the World of Warcraft MMO.

With Blizzard currently focusing all of its real-time strategy mojo on the StarCraft series, it may be a very long time before we see a real Warcraft IV. In the meantime, modders have us covered: Warcraft: Alliance and Horde takes the sci-fi StarCraft II and replaces everything with the characters, setting, and lore of the Warcraft series.

Originally launched in September of 2013, the mod's creator recently launched version 2.0, adding two new playable factions as well as a slew of tweaks and improvements.

Created by modder StevenLuo, Alliance and Horde currently consists of six custom maps that are available via the StarCraft II Arcade—Blizzard's official distribution platform for sanctioned mods. More than just a graphical overhaul, the mod features four playable races, new scenarios, custom units, and several heroes to control.

In addition to the Alliance and Horde, the recent update adds two new playable factions: The Undead Scourge features a necromancer unit that can temporarily transform ghouls into giant zombie monsters, while the Burning Legion can summon demonic units for free from a special "dark portal" structure.

After downloading it from the StarCraft II Arcade, Alliance and Horde's custom maps let players duke it out against the AI or each other, all for free. All the mod requires is the basic StarCraft II game, which itself can be downloaded for free from Battle.net.
