The repair halloween quest is a bugger. To repair the droids, type repair droid. Sometimes you get lucky and it takes on the first try, sometimes it kills the droid. You get spammed with smokers, spitters, tanks, chargers, jockeys. Good luck getting through that. Don't berserk or nova cuz it will the droid. The best thing to do is spam repair droid. It takes about 2 seconds between commands for it to register. It can take up to 10 times of typing repair droid to repair the droid. If it doesn't take on the first on, get the f out of there if you can't kill the gobs of zombie. Flee, then run back into the room and repair before you can get attacked. Rinse and repeat up to 10 times.
