Upon arriving at the gates of Sanctuary, the Vault Hunters are asked to rescue Roland, now leader of the Crimson Raiders, who has been captured by a bounty hunter called the Firehawk.
Along the way, Handsome Jack taunts the Vault Hunters, while the Guardian Angel offers advice and comfort. Claptrap and the Vault Hunters are able to escape the frozen wastes after defeating Captain Flynt, the local bandit leader, and retaking Claptrap's boat. The Guardian Angel contacts the Vault Hunters and instructs them to accompany Claptrap to the city of Sanctuary, and to join the Crimson Raiders, an anti-Hyperion resistance movement, in order to defeat Handsome Jack.
The Vault Hunters regain consciousness in a frozen wasteland and are found by the last remaining Hyperion CL4P-TP ('Claptrap') unit. However, the train is a trap set by Handsome Jack, and it explodes. The opening cutscene introduces the four new Vault Hunters as they ride a train on Pandora.
