blue slugcat versus chimney canopy (from wall)

my third attempt on the notorious trek from the wall to industrial, a critical point in all of my hunter runs, though this is only a survivor playthrough, it's still very difficult. missed highlight: some stray grapple worm latched onto me and saved me from a fall all the way down to industrial complex, my saving grace, we later died in the rain after being unable to get over a platform :(
