So Miros mentioned this game a while ago in a status update, and it intrigued me, so I checked a few videos, then decided to take the plunge (even though it was early access, but I'm not as worried about it as I normally would be because while the studio is new, the devs are actually all experienced pros).
Right now it's just single-player sandbox survival in the Canadian wilderness, and you have to manage fatigue, cold, hunger and thirst. They plan on adding single-player story later. No zombies, no 1000m snipers, just you and the wilderness and whatever loot you can find and keep in good
