From the earliest days of the Rebellion, R2-D2 and C-3PO have been at the heart of galaxy's most dramatic events. Now these Droids arrive to Imperial Assault in the R2-D2 and C-3PO Ally Pack. Its two detailed plastic Droids come with new cards and missions for both the skirmish and campaign games. For the skirmish game, this expansion includes new Command cards and a skirmish map with two unique missions. In a campaign game, the Rebels gain a new side mission and the ability to field these two plucky Droids as allies.
