I mean, that's the pure joy of the game, the very intention of Sandbox (turning Survival). It's all about your own adventure, no one else guiding you along the way or providing you with any kind of support. And, according to the FAQ's on the official website, Hinterland has no intent on adding a multiplayer feature to the game in any way, which is to my utmost satisfaction.
