I've only "beated" it once with a Rodian lightsider. Now I'm working on it with a male Human darksider. I was just about to beat the (extemely stressful) Chandrilla mission when I accidentally deleted the game and must now do the entire level over again. That Rift Sanctuary was one of the most impressive places in the GFFA. A disruptor rifle is your best friend in that level.
