Thrawn's Revenge is a large-scale mod for Empire at War: Forces of Corruption. It includes the events of the Galactic Civil War after Palpatine's death at Endor, up until the signing of the Pellaeon-Gavrisom treaty. If you own the Steam version of EaW, you will have to complete extra steps to run the mod after installation. Please see the manual for these steps.
This is a specifically modified version of the mod to allow some level of compatibility with the GoG and retail disk copies of Empire at War. The Steam version of Empire at War has had several stability patches which we have taken advantage of during mod development, so we recommend getting the Steam version (otherwise we basically would have had to stop at 2.2.5 anyways)
