Rust

Rust is a multiplayer open world survival video game developed and published by Facepunch Studios for Windows, OS X and Linux. Players survive in a harsh world starting with a rock and a torch and need to gather cloth, food and ore, craft tools, build housing and team up with other players in a PvP area. Rust began development with the framework of DayZ and featured elements of Minecraft, and is built on the Unity engine.

Rust was also part of the Yogscast Humble Bundle for the 2014 and 2016 Christmas Livestreams.

Many Yogscast members, including Duncan, Sjin, Chris Lovasz, Hannah, Panda, Kim and Zylus have videos of this game, most emphasising the fact that it is difficult to play together due to the difficulties with the game's random spawn location feature. Sips has also mentioned it is difficult to record without doing so in bulk, as servers are live and buildings and progress can be instantly halted due to death or vandalism. The game has also been livestreamed in 2014, featuring Lewis and Turps.
