Invasion of The Halloween Fiends

Invasion of The Halloween Fiends launched on October 1, 2024 as a self-described approximately 1-hour Halloween horror experience. The developer pushed a small bug-fix patch on October 3, 2024, and has since posted news focused entirely on promoting their next games (Hell of a Birthday, Gordy, and Bite Night 2) — none of which reference any additional content for this title. The store description presents the game as a complete, standalone experience with no mention of DLC, updates, or future content. There are no unreleased DLC listings, no roadmaps, and no developer statements indicating further additions to this game. MyGrandfather Games appears to operate by releasing small, self-contained horror titles rather than expanding them post-launch, and all post-launch activity for this studio has been directed toward new releases. The game shipped as a finished product.
