The story behind these levels is that you are smuggled on board the Deathstar at the time when the Millennium Falcon was brought aboard in Episode 4, you are a spy sent from Alderan to infiltrate the Imperial "flag ship" but what you didn't know was this "flag ship" is in fact the deathstar, you are inside a container which is unloaded from a shuttle and from here you must find your way around the station and to gather as much inelegance as you can.
It is on board this station that the plans for the Deathstar 2 are found!, these plans are smuggled off of the station and used in Episode 6.
This level starts in a landing bay similar to the one seen in Return of the Jedi, and some other parts of the level resemble imperial architecture seen in the films, you may notice the blast doors, they took a bit of time to get right, including the frames.
I try to vary the levels as much as i can but the DeathStar is quite a boring place visually, as from the films we only saw.001% of what's actually inside of it , but that's gives me plenty of room to add as much of the Star Wars universe as i can, now all six have been made i can have references to all of them in my designs.
