Decided to hop on over to the neighbors base to look things over again​ when I noticed that when in the guest planet mainframe two things listed really stand out

Base Controls: Limited

Construction Permissions: Unavailable

Possible multiplayer confirmed?

Maybe In a future update we can allow others to fully access our base even possibly build on to it or co-habitate together

Maybe build a city? who knows but I think I just discovered something here and if it's true it'll be awesome
