First of all, you need to tend to alot of bugs in this game, here's some examples, when i join my friends game (after like 5-6 reboots of uplay for it to work) we experiance alot of issues.
1, I see enemies that's not even there for him.
2, Lagspikes (we have good specs)
3, You can only unlock stuff from radiotowers if you are the host (takes away ALOT of fun for the other coop player)
4, Falling through the map at random
5, Not able to share skins when you skin animals...
And alot more to take care of, like server stability...
