Evaluation

Expedition to the Backrooms entered Steam Early Access on July 20, 2025, with a substantial launch build featuring large levels, a sublevel system, multiplayer support for up to 6 players, two endings, and more. The developer then spent the following six months on a major foundational rebuild, which shipped on May 23, 2026 — described as a complete reconstruction of the game including a character rework, graphics overhaul, real voice actors, new inventory and save systems, and entity rework. A smaller feature update followed on June 4, 2026, adding a redesigned map selector, lobby UI changes, and a flashlight for the camera item. A January 24, 2026 developer post acknowledged delays caused by personal issues but confirmed the lead developer had fully returned to work, with new team members brought on to help accelerate progress. The game is explicitly in Early Access and the developer has communicated active, ongoing development with no indication of a planned 1.0 release window or completion of content work. The most recent official communication was June 4, 2026.
