I decided to not do the other Far Harbor Settlements this time as they are a major part of the DLC gameplay and you need to do all the  Far Harbor Town quests to unlock them, if you need those, they are available in v0.3

v0.52 ALL DLC +UFO4P (v0.51 + Covenant and Vault 88, see diversions)

Future editions:
v0.6 ALL DLC without UFO4P

v0.50 FO4 1.10.106 + ALL DLC + UFO4P v2.0.4 with 26 Settlements Unlocked.
Very hard Mode, Female Sole Survivor, LVL 12 with 11 spendable perkpoints.
This is equal to the v0.3 but with an unleveled player character instead of the OP LVL 104 one in v0.3.
NOTE: Has been (or, will be) updated to include Covenant and some of the DLC settlements in v0.5+

Procedure:

- These settlements are unlocked with proper killing or questing and i avoided unrelated locations* and/or quests**.
- I did not use console commands that can have a bad influence on the savegame, like questbugs etc,
- Used console commands: player.modav 2c9 'xxx' (v0.3 only), coc 'cellname', tgm, kah, save 'xxx'
- I've build some turrets and gave preplaced settlers food and water when needed.
- Left as much as i could untouched, no bobbleheads (v0.50 or magazines) collected no scrapping done.
