I have to say, Shadows of Kurgansk looks pretty damn interesting for an action and survival game and it's now on Linux.
I'm not usually into such survival games, but considering it's a single-player experience where I won't be battered to death by naked people (Hello Rust) it might be worth a shot.
About the game (Official)
“Shadows of Kurgansk” is an adventure game, where you need to survive in an area full of danger and mystery. Your goal is to stay alive and find the way out, fighting
monsters and completing story driven missions.
To stay alive you will need to hunt, gather supplies, build storage and asylums. You will be able to create tools, clothes and equipment. In due time your life will become quite comfortable, but the Zone is not exactly the best place to spend the rest of your time. You will need to find the way out. Even if you fail, remember – death is only the beginning. The beginning of a new journey!
If you check it out be sure to come back and tell us if it's worth it, my budget has been blown this month so I can't check it out right now to give you any proper thoughts.
