The price on the Rogues and Villains expansion pack for Star Wars Armada is marked down on Amazon today. At $10.39 it's the lowest price for this expansion I've seen (both on Amazon and elsewhere). Base game required to play unless you just want the miniatures for your own purposes.
The expansion pack adds 4 heroes on each side to your game, including Han Solo's Millennium Falcon for the rebels and Boba Fett's Slave 1 for the Empire (along with several more of the galaxy's most notorious rogues and villains). All feature the "Rogue" ability and are able to both move and attack during the squadron phase.
