    And for those that prefer a map method:

    only issue i've found is all the alien ones are the same marker, so if its not night AND raining, its hard to tell which from which.

    i know i managed to have most of the boards and alien stuff get discovered as i was driving around getting the roads, even if my house wasnt upgraded enough to start collecting them, so i just needed the location of one or two of each.

    I2xINCHxTONGUEHas anyone else had trouble with this not unlocking? I've picked up all 25 power cells, is there anything else I need to do?

    TheIcemanCometh@I2xINCHxTONGUE - the guide does not specifically state this, but you need at least the alien plants as well, hence the "debris" in the description instead of "power cells". There are 25 of those as well, and they can only be found when it's raining.

    Here's that same map but I colored the cells green and the plants pink. And it's a direct link to just the image, no reddit or imgur pages you gotta click through.
