Heartworm

Heartworm launched on July 31, 2025 after a lengthy development journey that included a publisher falling through in October 2023 before DreadXP stepped in as publisher in February 2024. The game released as a complete, self-contained 4–6 hour narrative horror experience. Following launch, the developer shipped a series of bug fix patches in August and early October 2025, and then delivered the 1.1 update on September 29, 2025 — a substantial post-launch patch adding a new "Challenge" difficulty mode, a new camera mod, enemy balance adjustments, final boss rework, Steam trading cards, and various bug fixes. The official soundtrack was also released the same day. A hotfix on October 2, 2025 addressed a save/load issue introduced by the new camera mod, and a further Unity security patch was applied on October 10, 2025. The 1.1 update represents the only named major content addition post-launch. There are no unreleased DLC entries on the store, no announced expansions or future content, and no developer statements indicating further updates are planned. The game's store description presents it as a complete, story-driven product with defined runtime and features. The October 10, 2025 patch is the last developer communication on record, and nothing since that date suggests ongoing content development. With no outstanding commitments and no sustained pattern of recurring major content updates beyond the one post-launch improvement patch, Heartworm appears to have shipped as a complete product. The 1.1 update rounded out the launch experience, and the September 29, 2025 date marks when that content became available.
