A singleplayer story mod for Jedi Outcast revoling around the Sith Stalker from The Force Unleased.
A bit more tinckering and I was able to get this to wrok, which I'm quite pleased with. Having repalced the imperial shuttle with a rebel transport, I wanted to do the reverse as well but ran into some problems with the shuttle model. At the same time, I also felt that a Sentinel SHuttle would fit the role better.
Finally, after some slightly tweaking of the shuttle model, I managed to make this. Like the other ships, this'll be in the 1.1 update.
