Hello my friend, we didnt get to test it as much as we wouldve liked. Unfortunately all of the things that spawn are very very hard to find. But if you look around. Random weapons spawn around the entire map every 1 minyte. And water canteens spawn around the map aswell. Close to pools of water!!!
A canteen fills thirst completely.
I found that the best strategy. Is to look around and find weapons. Drop all of your weapons in one area. Using right click. To keep them close by. And then go hunting. But don't pick up all food!! Leave food on the ground until you need it. While you are hunting you will find water.
Another strategy. Mirages spawn when you are below <50 water. Animals spawn with these mirages. If you keep yourself below 50 water and jist farm animals for meat for a while. Keep all meet on the ground while u then go look for water.
Enjoy! Sorry it couldn't be as polished as we would've liked!
