From the post:
Across the galaxy, the Empire chokes out the last fires of the Republic, smothering freedom wherever they can find it. Yet a noble Rebellion has arisen to combat the Empire, and new heroes are born every day—entering the ranks of the Rebel Alliance and doing their utmost as pilots, soldiers, saboteurs, and diplomats to bring the Emperor’s tyrannical reign to an end.
The legends that these heroes forge are now yours to play. The Legends of the Alliance companion app for Imperial Assault is now available for download from the App Store or Google Play!
