I find the scanner to be pretty useless. I have stopped building it. It doesn't find the materials I need it too and it reports materials that arent' even there. Like my base always has a couple of metal scraps.
I think a map like in Minecraft would really work here. It fills in whatever area you have been in, for just a few meters around you. But I definetly would like to have some kind of map.
Or maybe the scanner could come in use here. Start…
This is a good idea because I recently discovered it doesn't take long to overfishing your area and new ones don't regenerate. The realism of this game astounds me.
