Rust is a survival video game developed and published by Facepunch Studios in February 2018 for Microsoft Windows, OS X, and Linux. The game has only a multiplayer mode. Rust was created initially as a clone of DayZ, a popular mod for ARMA 2 with crafting elements like those found in Minecraft. The objective of Rust is to survive in the wilderness using gathered or stolen materials. They must successfully manage their hunger, thirst, and health or risk dying. While there are bears and wolves, given the game is multiplayer-only, the primary threat is other players. Combat uses firearms and primitive weapons, such as bows. In addition, attack helicopters, a vehicle controlled by non-player characters, will occasionally fly around attacking heavily-armed players, though they can be taken down with persistence. The game features crafting, though initially, only limited options are offered. To stay protected, players must build bases or join clans with others to improve their survivability, with raiding being commonplace and done more frequently by large clans.
