Best Indie survival game on Steam

If you haven't tried it yet, you should go for Project Zomboid. It's got some really old-school graphics, but it's a real in-depth simulation of surviving the end of days / zombie apocalypse. There's hunger, thirst, need for sleep, occasional insanity and panic attacks, also crafting, cooking, exploration and more. Check it out. I've spent countless hours with this game. It's not a story of how you survive zombie apocalypse. It's the story of how you die.
