Whether as gambler, rogue or businessman, Lando Calrissian preferred to avoid Imperial entanglements. After a deal with Darth Vader went horribly wrong he became a general in the Rebel Alliance.
Lando Calrissian has three personas in the game, which are treated as different characters. This is his original (Bespin) persona. Lando Calrissian was introduced in version 1.0.
This version of Lando does not unlock any scenes. As a Rebel, he is actively chased off of any Imperial level.
