when you invite your friend to your game they join into your shelter and you can have clans, or four man teams that help you defend your shelter against others trying to raid, and add defenses like turrets and walls to your shelter and bigger shelters that could maybe eventually be turned into forts and defend your fort against other teams and maybe have like servers with up to like maybe 6 teams and 6 shelters per server, this could add another aspect to the game to make it more unique and add another way to aquire weapons and loot, but raiding forts should not come easy to any extent.
