The Esseles, a Republic transport that routinely carries civilians to and from the Republic capital world of Coruscant, has come under assault. Attacked by a powerful Imperial warship under the command of a ruthless Moff, the outgunned and outnumbered crew of the Esseles ready themselves to fight against the coming Imperials.

Having booked passage on the transport to Coruscant, champions of the Republic now find themselves thrust into this dire situation. Taking up arms, they must now band together to battle back the Imperial boarding parties, defend the passengers and crew of the Esseles and free the transport from the Imperial warship.
