i'm amazed by this alpha coop so far for example how far can you see your friend ? - you can see each other from everywhere (but only if you in same system) http://imgur.com/a/w4Y9Y

you and your friend can see each other base remember you have to leave the planet and go back to the place that your friend buliding so you will see base just being changed or simeple just restart the game

you and your friend will see same species , rock , places , npc base *every npc base including missing person base EVERYTHING , everything that not move

you and your friend can see Crashed ship ! this is so cool http://imgur.com/a/01NWv

like i said everything that not move you and your friend will able to see and share
