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.
I have a ton of screenshots from my 2.3 preview playthroughs (you can watch the Imperial one here: Youtube.com ) so i'm gonna start moving a bunch of those to ModDB. This screenshot in particular shows our new Vigil-class for the Eriadu Authority, one of several new units coming to 2.3.
