Sentry is being used by Facepunch Studios to prioritize bug fixes for their game Rust, a multiplayer sandbox survival game that requires players to collect resources and craft items to progress without objectives or storyline. The use of Sentry has allowed the developers to efficiently manage bugs and improve the overall gaming experience. Garry Newman, the creator of Rust, discussed his experience with using Sentry in an interview, which is available on the full story in a customer spotlight on Fixing Bugs at Facepunch Studios.
