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.
Alongside the Warlords themselves, 2.2 will have a bunch of other changes. One of these changes is something I'm working on (which will also be used by Bullet in AotR) is adding static defense turrets to base buildings. Here's the Imperial barracks with a standard AI turret built in.
These will be present as targetable hardpoints on the buildings, similar to the Underworld palace. 2.2 in general will have a lot more hardpoint representation on ground.
