Evaluation
Hidden Deep is a solo-developed sci-fi action game that entered Early Access on January 24, 2022 and remains there. The developer (known as Wookie/Luke) has continued working on the game throughout its Early Access period, shipping major milestones along the way: a content update with new levels and enemies in April 2022, the Survivor Mode roguelite overhaul in June 2023, and the initial multiplayer release in December 2024. Through late 2025 and into 2026, the developer expanded multiplayer to eight players, restored split-screen, and addressed a steady stream of bugs and stability issues.
Most recently, on July 2, 2026, the developer posted a detailed announcement confirming that the next major update is in progress and will include a random level generator, new monsters, new environmental objects, and a brand-new extraction-shooter-inspired game mode — all playable in both single-player and multiplayer. The developer acknowledged a recent period of silence but was clear that the game is not abandoned and that this update is coming.
The game is still in Early Access and has not announced a 1.0 release date. The developer's communication is active and a specific batch of new content has been explicitly committed to.
Evidence
Developer announces random level generator coming soon, along with new monsters, new environmental objects, and a new extraction-shooter-inspired game mode for both single-player and multiplayer.
