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.
One of the new ships for the New Republic in 2.2, the Dauntless-class. More powerful but less versatile than the Assault Frigate, the Dauntless makes a good complement to any fleet until you have access to the BAC.
