How would you reach them you should find a radio and make a channel for your friends or spawn with a radio.

Rocket has touched on it briefly in the Reddit Q&A.

Q: Will there be a possibility of having character slots when the stand alone comes? using more than a single character sounds like a must, right now i'm up at the airfield and i have absolutely no way of helping my friends that just began to play the game because i'll take a long time to travel down and i might die and lose everything just trying to help. Also, will there be a "party" system so you can see where your friends are with some sort of indicator?

A: Group play is very important one of the key design priorities. But we need to explore how this mechanic will work and not disrupt the disorientation that occurs on death.

Q: Will there be more group functionality? Group leader can leave points on map for group to see, maybe see where squad members are?

A: Group functionality is a priority but we need to be careful not to remove the disorientation on death and from trying to find people, that is part of the disaster disorientation and fear.

Q: What are you planning on adding to encourage people to teamup? What sort of community features are you planning on adding to help and/or balance cooperation in the game?

A: Group/community features are a key design consideration that will be closesly linked with construction. I.e. you build a base and the better it is the better options you have, such as storage and respawn etc...
