Before Herbert will help us, we need to find his creepy love tapes to Scarlett. How annoying. Oh well, swing around and head north, to the right of the big ship (we used its anchor to get up here, remember?).
Head past here and down into Coobie Gorge. Deal with the Spiderant variants as we go, shooting them in the abdomen to deal with the quickly. Remember that grenades can he highly effective tools here.
Keep working towards the waypoint. You’ll have to go 'around' it and then engage in some light platforming, but you’ll soon reach it. And then it will explode. How annoying. Again.
One piece will land nearby. Simply head back over the bridge to the east and then hang a left to the little dead-end outcrop, the first letter is sat here.
Head back over the bridge then turn right where you previously went left. Deal with the double anchorman attack and then head inside, battling your way through the stream of pirates that will try and stop you. Again, tight quarters inside this ship so bring out a shottie if you can and use the huts for cover should you need it. Just climb all the way up to the west and you’ll find the next tape outside, in the middle of a platform.
Wander over the bridge to the south and deal with the spiderant onslaught. Once eradicated, grab the third tape from atop the building. You’ll have to jump up from the western side.
Continue south, towards the waypoint, and deal with even more spiderants. The final tape is sitting above you, on a metal walkway. Investigate the wall south of the waypoint to find the up-ramp.
With all four tapes in hand, head back to Herbert and then open the chest to finish this mission…
