Republic at War is a total conversion modification for Star Wars Empire at War Forces of Corruption. The mod replaces the Empire with the Galactic Republic and the Rebel Alliance with the Confederacy. Republic at War focuses heavily on the theatrical films but also contains content from the Clone Wars cartoon series as well as the expanded universe. Players can re-enact various Clone War campaigns such as the Outer Rim Sieges. Players will have the choice to fight as either the CIS or the Republic and wage war for control of the galaxy. Realism is key and players will have unprecedented control over how and where they fight. Push forward with an entire clone legion such as the 501st or 212th or overwhelm your opponent with a seemingly endless number of B1 battledroids. The choice is yours. There are also a number of expansions planned that will add new (as well as polish existing) content.
Both Republic & CIS (fighter) heroes will finally be worth purchasing.
The Republic heroes, specifically, excel in fighter combat and are much tougher to deal with. They are one of the (many) new options for Republic players to help keep the CIS fighter count low during the mid to late game.
