7 islands

[Ronnie&Reggie]

there are 7 islands, standing on radio mast (RM) island looking out to other island: to the left is the Lighthouse (LH) island going further left of LH is Lagoon (L) island, directly in from of RM is Air Plane crash (AC) island, to left of AC is Arch (A) island, to the front and slightly right of A is Sandbank (SB) island, and to the front and right of AC is SOS (sos) island. Submarine is on the reverse side of RM slightly right as you look out to sea.

i have found that by visiting each island every time i log in, new notes etc will spawn, if you stay on only 2 islands things will not spawn as frequently.

i have found all 6 notes and have repaired the radio mast and now have the gps which was locked in the black box at base of RM.

i have started the game 3 times and have found that the codes are different each time. you cannot unlock the black box until you have found all 6 notes.
the 6 notes are titled as follows:
1. beginning of the end
2. corporate greed
3. stranger occurrences
4. desperation & Discovery
5. chaos
6. alone.

they will only spawn when you found each one, the next then spawns.
my first was on large rocks facing LH by sunken car. if you have this one then i can tell you where to find the others, as they spawn randomly, but have a sequence for each set of numbers.

The only islands I've found the notes is on Radio and Lighthouse. You find red notes on Airplane Crash...which is a whole other adventure.
Have you found the same on your game?

I'm on 5 looking for 6 and 7. Think I'll check in the lagoon.

i found notes 1, 2, 6 on radio mast island. 3, 5 on lighthouse and 4 on arch island, the code i ended up with was in order of notes 168344, but you have to find all the notes before game lets you open box.
1. RM -large rocks facing LH by sunken car
2. RM - in cave under tower with keys
3. LH - on crate by cannon
4. A - 2 rocks in sea facing arch
5. LH - on wood scaffolding base of LH
6. RM - base of large tree to the left of RM (near where ancient lantern was found) when looking out towards Airplane crash island

Notes have random spawn places as well as other blueprints etc for every player. Location of the islands is also random.
