Having friends in Once Human means you can band together for missions, share resources, and even enable building permissions. This gives your friends access to the building, moving, and destruction aspects of your territory.

Think carefully before going through this process; granting building permissions is not something you should do lightly, as your friends can then easily build, destroy, or move structures at your base. If you trust your friends not to destroy things, then enabling permissions is an excellent way to collaborate on base ideas.

From the same permissions menu, you can also let your friends access your storage, which means they can remove or place items into your storage, barring your private storage, and give them access to the facilities inside your building.
