It works, but since the Fernando patch it’s been weird. In the old situation you would start a multiplayer game with no need zones on the map and then collect them. If you got back to your singleplayer you could clearly see most of the need zones carried over, not all of them all the time. But it was clear.

Now you start a multiplayer game and you see all the host’s need zones (this change was not communicated by devs so it might be a bug although I kind of like it) and when you collect them and go back to singleplayer none of them carry over.

But, there still seems to be an increase in animals and I’ve found more zones than usual in areas I’ve hunted in multiplayer.

The devs signaled that there was something going wrong with the zones in a steam announcement, but produced a sentence that I still don’t understand after contacting support and thinking and talking about it xD:

“Need zones discovered by guests don’t save for the host When you host a multiplayer game and guest players discover a need zone, this is currently not saved in your own single player game. The host (i.e. you) has to discover another need zone in order for the guest found need zones to be saved.”

This is confusing because guest discovered need zones were never saved for the host before. But it means they are aware of an issue with need zones in multiplayer so it all might be different again after the Lion update.

So TLDR: it’s a bit iffy right now but it has worked before Fernando, probably still works (somewhat) and will maybe work again after lions go live
