Rust

The object of the game is to survive in a harsh open world, starting with next to nothing and working to rebuild as the player sees fit. Wolves and bears represent a threat to new characters, but the primary danger comes from other players. There is no option to turn off player vs player combat. In order to survive, the player must craft tools, build fortresses, level up and team with other players. Unlike many other sandbox games, Rust only features a multiplayer mode.
