Features

Everything below runs in the current release. Footage is on its way.

An orc base in OpenWar3, training from the Altar of Storms

A faithful recreation

Every unit, ability, cost and timing is read straight out of your own Warcraft III: The Frozen Throne 1.30.4 install. OpenWar3 is original code and ships zero Blizzard assets.

Three Computer+ (Normal) opponents seated in a game lobby

Computer+

A second melee AI beside Blizzard's own, which is ported script for script. Computer+ never cheats at any difficulty, creeps, shops, and talks to its allies in team games.

LAN with zero setup

Run the desktop app on two machines and pick Local Area Network. Games show up in each other's list within seconds — no terminal, no accounts, no cloud.

The World Editor's map-and-quill icon

Campaigns & custom maps

Maps run their own JASS scripts on OpenWar3's interpreter, from the campaign chapters to custom games like Extreme Candy War.

Keeps itself up to date

The game checks for a new release at launch and offers it in its own message box. Say yes and it downloads, installs and restarts on its own.
