The Horse Armor Podcast guys (Nick & Tom) try out Rust, a Steam early access game currently in Alpha. The whole point of Rust is to survive and overcome the challenges of hunger, wild animals, and other players being dicks.
Be warned this game does have nudity, players start this game like the day they were born. Naked and screaming.
What is Rust?
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, and kill them for meat. Create alliances with other players and form a town.
Whatever it takes to survive.
