Star Wars™: Legion was recently announced, promising you the opportunity to command armies from the Star Wars galaxy and play out the unsung battles of the Galactic Civil War. Now, the Rebellion is ordering reinforcements to the front lines, bringing new troops and vehicles under your command! Fantasy Flight Games is proud to announce two new Rebel Unit Expansions for Star Wars: Legion.
With two new Unit Expansions, you have the perfect chance to supplement your Rebel forces from the Core Set, bringing more and more units to bear in the war against the Empire’s tyranny. Containing a powerful AT-RT walker and more Rebel Troopers for the Alliance, these Unit Expansions offer units identical to the ones found in the Core Set, letting you construct an army that plays the way you always wanted to experience the Galactic Civil War.
