When I try opening rust it says RUSTCL~1_Data missing. I thought to my self there must be a way to fix it and I look up on the internet because I am not good with computers but I love gaming. I especially love Rust, Rust was the first game I ever played on steam. When I looked on the internet there were no answers to my problem no one could help me so I was told to come here…

Please Help me I haven’t played Rust in 1 month.

Right click on Rust (in your Steam Library), open Properties, go to the Local Files tab, and click “Verify Integrity of Game Cache”.
This will scan the Rust folder for any missing files, and if it sees there’s one missing, it will download the file and place it where it should be.
It might take a while and you can’t use Steam during it, so.
