The Radio Tower is a little different. You need to zipline off a nearby hut to access the first level.
I wingsuit into the nearby outpost, but judge it all wrong. Regardless, it's a lot of fun. Fudge the landing, disable the alarm, and run and gun a bit. Good times.
Maw Docks and Repairs is interesting. I get pretty close and then disable the alarms, then do a stupid knife takedown and everyone gets alerted. A boat turns up, and I waste a bunch of time trying to take that down, despite the fact it's disappeared. Sloppy. Don't miss memory card 19.
Jetski race was nearby, so I had to take that, and then a wanted dead mission which is pretty hectic and lots of fun. Let me know what you think!
