I didn't use my target scanners as I didn't have a use for additional islands, I guess at that point the only reason you would need another island is for building space or more energy, but for me the plants at the concrete island were more than enough. I research all and then build them all though just as ending for the game and then started a new game. I actually didn't use the second toxic island at all except for the lighthouse. Maybe if they expand the game in the future I might continue.

its crazy that you have 3 of my islands all in different places, i have that desert and both polluted, but my polluted islands are next to each other on the lest and my desert is north lmao . what have you chose for your target scanners? i cant decide for my second

All of these islands are like 5 times bigger than the ones I have had spawn!! I feel robbed.
