I've done this bit before, but I'm replaying Abes Exoddus and forgotten how!

The secret area, Feeco Depot next to the Soulstorm door, I've got rid of the sligs, but then theres this drill that keeps going, and I cant get the three mudokons past it, and theres no way to sneak them in before you turn the drill on, and theres no way to deactivate the drill!

I think you should know which bit I'm talking about.
By the way (might as well kill two birds with one stone), this isnt related to this topic, but how do you get more stars? You know, upgrade your status?
