Thunderbrew
Thunderbrew was created as a fork of the Whoa project. Like Whoa, it aims to provide a fully-functional and open source version of the World of Warcraft 3.3.5a.12340 Wrath of the Lich King client.
Thunderbrew aims to provide a more easily accessible and feature-rich version of Whoa, while retaining its original mission of high code quality and adherence to original behavior.
Getting Started
Thunderbrew requires a full set of 3.3.5a.12340 archives to run.
