Wargus is a Warcraft2 Mod that allows you to play Warcraft2 with the Stratagus engine. The game looks and sounds almost exactly like Warcraft2. The gameplay is very close to Warcraft2's gameplay, with slight enhancements towards Starcraft and other more modern RTS games.
On first launch you will be asked for a copy of the original Warcraft2, so that the installer can extract the data. There's also a video tutorial on how to install Wargus.
Wargus is not an official Blizzard product, its a Warcraft2 modification, by Warcraft2 fans for Warcraft2 fans. You need a copy of the original Warcraft2. Warcraft is a registered trademark of Blizzard Entertainment.
Wargus is an open source software. It is developed at GitHub where you can submit bugs, request features and observe progress via issues.
