Those who have played KotOR 2, know its a broken game, which was rushed by LA to make the christmas rush of 04. The developer's, Obsidian Entertainment were forced to cut their development cycle back about 3-4 months. This meant ALOT of content originally planned to make the game awesome never made it in, luckily the cut content files were left in the Xbox version of the game, modders then exctracted it, examined it, and took it upon themselves to rebuild it!
This is the first mod to be released, the other which is also facing a immenent release, TSLRP mod will focus on restoring the game in general and not the Droid Planet or Peragus.
I am beta testing the TSLRP mod and all I can say is it sucks that none of the content will be Canon for the next Kotor.
The file itself is about 40MB in size and will ONLY work on the PC version of the game.
