I was practicing the bit in Dead End where you return to doc after powering the generator and found a way to prevent the zurks from spawning in the left alley, removing the death risk and saving potentially 5+ seconds.
I didn't see anything about this on the doc so thought I'd share

Nice find ! Just tested it, it works! Using the macro generally means we can just ignore zurks, but for anyone who doesn't or is on console, this is a lifesaver
