Rust is a survival game created by Facepunch Studios, headed by Garry Newman, the makers of Garry’s Mod. Inspired by games like Minecraft, and other wilderness survival games. – Rust aims to create a hostile environment in which emergent gameplay can flourish.
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.
