Epsilon-class shuttle
The Epsilon-class shuttle served as a transport vessel for the Galactic Empire throughout the duration of the Galactic Civil War.
Behind the scenes
William W. Connors conceived of the Epsilon-class shuttle for the Star Wars D6 roleplaying module "Starfighters Down", which was featured in the periodical Challenge 38 back in 1989.
Within the adventure, the class's presence was solely noted in the overview, indicating its presence on Phaylenn. Following that initial mention, all allusions to acquiring a hyperdrive from a shuttle specifically refer to the Lambda-class shuttle; therefore, this documentation infers that the Lambda-class shuttle is the actual target in that scenario.
