3/25/13 - EDIT: I may do some more work on this with the newer versions of Tekkit, and possibly Feed the Beast.
Its not too detailed but I'm going to work on that. There's a cannon on top of the laser so it actually fires. You can distribute your own modified version as long as you give me credit for the original. Latest edition: http://dl.dropbox.co...th Star Map.zip
Details: Laser that fires with TnT, huge Ti Fighter fleet, access valve through bottom, All the Design is done, Now with random rooms: one is the reactor which you can blow up! also added fire charge cannons on the sides, You can now fire the main cannon from the inside also! The Reactor can be blown up from the outside by "rebels" You can choose an element of Jedi/Sith to be there are: Fire, Water, Ground, and Grass, elements!
Technic Pack Version Here: http://dl.dropbox.co...star Tekkit.zip
NOTICE: All of the Newer versions of Tekkit should work, however if they fail, use any version still in 1.2.5
IMPORTANT: If you get lost or die, the coordinates are: x:224 and z:-1713
I just placed a bed, so sleep in it at your first chance!
Also if there's anything you want me to add to it then just say so!
NOTICE: Death Star looks much better with almost any texture pack accept the normal in-game one, as long as it alters the look of cobblestone, then its fine. The one I used is here: http://fl.xrbpowered.com/ it looks awesome!
Spoiler:In Tekkit its the same accept there's a remote firing system for the cannon next to what should be spawn, most of the redstone was replaced with redpower wire, and there are nukes in the reactor. hehehehe
There's also a sort of easter egg with the laser in tekkit version, watch the laser at night when using the remote firing system.
