Evaluation
DIMENSIONAL SLAUGHTER entered Steam Early Access on October 11, 2022, with the developer (Bashir "ManliestDev" Kashalo) explicitly promising additional content as the game developed. The game has received four major content updates since launch: the Early Access release itself (October 11, 2022), Sigma 6.0 (February 26, 2023), Sigma 6.5 (May 18, 2023), and Sigma 7.0 — "The Inbetween Update" (January 27, 2024). These updates added new dimensions, weapons, enemies, movement mechanics, a new antagonist with voice acting, a midway checkpoint system, and substantial quality-of-life improvements, demonstrating a sustained pattern of meaningful content additions across the Early Access period.
However, as of June 21, 2026, the last developer communication of any kind was the Sigma 7.0 update post on January 27, 2024 — approximately 17 months ago. This significantly exceeds the historical update cadence of roughly 3–9 months between major releases. The game remains in Early Access with no announced 1.0 release target, no roadmap for remaining content, and no developer statement explaining the extended silence. While the developer has been active on Twitter and Discord (mentioned in posts as channels for more frequent updates), no official Steam communication has occurred since January 2024, making it unclear whether development is still ongoing.
Evidence
Sigma 7.0 major update shipped — the most recent developer communication on Steam. Added a new dimension, 2 master levels, a midway checkpoint, new weapon, new enemies, new movement mechanics, and voice acting.
Last official Steam post from the developer. No updates, patches, or announcements have appeared since January 27, 2024 — approximately 17 months of silence as of June 21, 2026.
