The first one is for the show off trophy, basically I have to jump at an angle so I dont do a leap of faith, and then parachute onto the zipline.
A ghost run is pretty much impossible with fists due to both captains being so close together, so I decided to go back to Mysterious Death. I used the poison bomb and smoke bomb to lure them to one spot and take them both out at the same time.
The first one was great, like: "Wait, what, how..." And then you dropped of the zipline to kill the captains.
