Thief Gold (1999)

Thief Gold is a 1999 classic stealth game that arrived on Steam on May 22, 2012. It is a definitive, standalone release that bundles the original Thief: The Dark Project (12 missions) with the Gold update (3 additional campaign missions and new enemy types) — the store description explicitly describes it as a complete package. Looking Glass Studios, the original developer, closed in 2000, so no further development from them is possible. The game launched on Steam as a complete, finished product with no post-launch content cycle. The only recent developer communication on this Steam page — a June 7, 2026 announcement — is not about new content for Thief Gold itself. It announces Thief: The Dark Project Remastered, a separate upcoming product being developed by Nightdive Studios and Eidos-Montréal, published under Atari. That remaster is a distinct Steam listing and does not represent new content for this existing Thief Gold release.
