The only aim in Rust is to survive. To do this you will need to overcome struggles such as hunger, thirst and cold. Build a fire. Build a shelter. Kill animals for meat. Protect yourself from other players. Create alliances with other players and together form a town. Whatever it takes to survive.
It looks like an interesting game and it's good to finally see it on Linux as well as Steam. It's a very early version though so be wary. I can't wait to check it out personally, have you tried it yet?
It's on Early Access with this note:
QuoteWe are in very early development. Some things work, some things don't. We haven't totally decided where the game is headed - so things will change. Things will change a lot. We might even make changes that you think are wrong. But we have a plan. It's in our interest to make the game awesome - so please trust us.
You have been well warned folks, it can change with each new release.
Sadly we cannot embed the trailer here so go check out their homepage
