Hiding from the Hand

OK, FINALLY got the Projector Blueprints (see my post in the bugs section), built the projector and took it back to the Cyborg. Now, I've already wasted over 600 energy walking back and forth on the blasted thing....and I get apparently told to go explore the collapsed tunnel???? Isnt that how I got where I am????? WHAT collapsed tunnel, if not the one I took to get where I am? I honestly have no desire to fritter away another 600 energy aimlessly wandering.

Any hints from someone who has completed this thing?

edit: OK, the collapsed tunnel is just to the right and doesnt show on the map. BUT, you have to be lvl 36, to go thru to the next area...so might as well wait till then to take the projector to the cyborg...for those coming along behind me.
