Rust Family Sharing support has been temporarily discontinued.

Players using Steam Family Sharing to play Rust have been met with an unpleasant surprise - support for this feature has been temporarily discontinued.

No official reason has been given for this decision, nor is there any timeline for when players will be able to use Family Sharing again. Currently, Steam offers the game as a standalone purchase for all Family Sharing accounts.

Unfortunately, it appears that family sharing support in Rust will not be returning in the foreseeable future.
