OMEGA PHENEX is an eight-year solo mecha shooter project by Surume Manju, now with Astrolabe Games as global publisher, targeting a PC via Steam release within 2027. The developer left his video production job in August 2026 to finish the game, and a playtest is running until July 25, 2026.
OMEGA PHENEX (Commenced Project Six) is a high-speed mecha shooter built by solo developer Surume Manju under the circle Surume Game Koubou. The project began as a way for Manju to learn Unreal Engine while working as a CG designer at a video production company. He has worked on it for about eight years, mostly alone, and it is built with Unreal Engine 5. The game takes influence from Armored Core: For Answer and puts players in the cockpit of the highly mobile mecha Icarus across large maps for over 30 missions, including annihilation battles, boss fights, and escort missions. An arena mode for one-on-one battles is included, and mecha can be customized with parts and color schemes, with a Tune function for adjusting durability, mobility, and weapon performance within a cost limit.
On July 8, 2026, Astrolabe Games announced it would handle global publishing. The deal covers global promotion, translation, console version feasibility study, and distribution support. The game is targeting a release on PC via Steam within 2027. Astrolabe's involvement follows a period of community interest: an open beta test on Steam that began April 25, 2026, drew over 70,000 participants, and the game has accumulated over 130,000 Steam wishlist registrations. A crowdfunding campaign on CAMPFIRE has raised approximately 6.5 million yen, more than double its initial target.
Two months later, Manju told 4Gamer he left his video production company in August to finish the game ahead of its release next year. He is showing OMEGA PHENEX in the SELECTED INDIE 80 area at Tokyo Game Show 2026, which runs September 17 to 21. The release window is now the part of the project outside his control, while the development work has moved to a full-time footing.
