Hurtworld (Incl. Early Access)
If you find survival games become too easy once you manage to scrap together some resources, Hurtworld will be a refreshing change. It is a hardcore multiplayer survival FPS which is meant to punish noobs mercilessly and reward those who really know what they’re doing.
The devs claim that their aim is to punish those who don’t take the time to learn to play the game properly.
