Rust is a multiplayer-only survival video game in development by Facepunch Studios for Microsoft Windows, OS X, and Linux. Rust was originally released onto Steam's Early Access program on 11 December 2013. Rustwas initially created as a clone of DayZ, a popular mod for ARMA 2 with the addition of crafting elements.

The game tasks players to survive in the wilderness by crafting items using the materials they gather or steal; the player starts with only a rock and a torch. There is only a multiplayer mode and a prevalent concept in Rustis to form and join clans with other players. Raiding is a very common action, usually done in large clans. Since Rust's first alpha launch, animals, hunting and the ability to craft armor and weapons have been added.
