I wonder if it's basically just DayZ players moving to Player Unknown's Battleground? Also... Something interesting... Valve has hired a bunch of the people that made Kerbal Space Program and they are now making a new game for Valve. I wonder if it will be space related in any way?
I don't know much about it other than it looks like a DayZ clone without Zombies and it's multiplayer only *shrugs*
LOL Valve making a game... but seriously any source on that one. I know a bunch of the KSP folks got recruited by Valve but for what purpose I have yet to see.
