Death Star Tunnel Run
After I get shot down the tube by the container accelerator rings, and go a little further, I get to a fork in the tunnel. If I take the left fork, and then travel in the tunnel with tubes that run along the length of the tunnel, you come out in a chamber with a lens at each end. You can destroy the laser power source in this chamber, but after I do that I always get destroyed by the next laser beam firing because I can't figure out how to get out of this chamber. I look for the way I got in there but I can't seem to find it. What am I doing wrong?
