Imperial Death Star style corridors. A modular set that allows you to create any configuration that you desire. I have based this layout on the floorplans for the sets that they used in Star Wars: A New Hope.

I'll soon be working on some add on packs that will add new specific locations that can be integrated with the corridor set, such as security offices, the tractor beam control console, and the chasm that Luke and Leia swing across.
