Like other Ally Packs, the R2-D2 and C-3PO Ally Pack offers essential new cards and missions for both the campaign and skirmish games, alongside two detailed plastic figures required for fielding R2-D2 and C-3PO in Imperial Assault tournaments. For the skirmish game, this expansion offers Command cards that open powerful new strategies and a new skirmish map with two unique missions. The Rebel heroes in a campaign game also gain a new side mission and the ability to field these two plucky Droids as allies.
