Death Stranding – 100% at last :)
It took me some time, but eventually I made it – 100% :)

Just one remark from my side. If you plan to get Birth of a Legend and Growth of a Legend aim for the second one. Do everything on Hard level. Otherwise you will do the deliveries twice. Avoid long trips for timed deliveries, focus on short tasks. It is also a good idea to combine deliveries to reduce trips. For all miscellaneous tasks involving fighting Mules or Terrorist, collect as many tasks as possible so you have to fight just once. Riot shotgun will do the thing. Just hide behind the corner and clean up the camp.
And one more suggestion. If you want to change the difficulty of the game, make sure to save the game after you have made your last order. Otherwise, your game state will be restored just before the last delivery, and it will count as if the lowest difficulty was set the whole time.
