The aim of the game is to survive. To do this the player should gather resources. Hitting a tree with a rock will provide wood, hitting a rock with a rock will provide rock and ore. A hatchet can then be crafted from the wood and rock, allowing faster gathering. The player can then hunt a variety of wildlife such as boars, chickens, horses, bears, wolves and deer. Once an animal has been killed it can be butchered to gather its meat and skin. A Camp Fire can be crafted using wood to cook the meat, making it edible.
There are two major dangers in the game:
Since Rust is a multiplayer game, there will be other players also trying to survive. Unfortunately for you they can find you, kill you and take your stuff. Fortunately for you – you can kill them and take their stuff. Or maybe you can make friends and help each other survive. Rust's world is harsh – so you might need to make friends to survive.
The environment is not kind. Bears and wolves will chase and kill you. Falling from a height will kill you. Being exposed to radiation for an extended period will kill you. Starving will kill you. Being cold will kill you.
There are two main versions of the game. There is Experimental, which is the current version of Rust and is updated regularly. And then there is Legacy, which is the older version of Rust that is no longer updated.
