Eclipsium

Eclipsium launched on September 19, 2025 as a complete first-person horror game. After launch, the developer (Housefire) shipped several bug fix and quality-of-life patches through December 2025, adding features like a chapter selection menu, keyboard remapping, and ultrawide monitor support. On August 20, 2026 — roughly 11 months after launch — the developer released "The Dark Tar," described as their biggest update yet and delivered completely free. It adds 4 new story interludes following the Princess' journey, an entirely new location, visual improvements across key areas, full Steam Deck support, sprint/movement speed adjustments, and significant technical optimizations (up to 5GB VRAM reduction, up to 4GB disk size reduction). The same post also announced the release of the official soundtrack as a paid digital DLC, which is listed on the store as unreleased pending imminent availability. The developer stated it would be "available for purchase shortly after the update — probably in the next few days," and a physical CD/vinyl release is available for pre-order with an estimated ship date of Q4 2026. This establishes that Housefire is actively developing and expanding Eclipsium beyond its original launch content. While no further content has been explicitly promised beyond the OST release, the developer's willingness to ship a substantial free content update nearly a year post-launch signals ongoing engagement with the game. The game has now crossed from post-launch maintenance into a demonstrable pattern of substantial post-launch content delivery.
