About Operation Novem

Operation Novem is a 2D/3D CG animated RPG sandbox from abcdfgdev, built with the Others engine. You play a male squad leader assigned to SEER, a mysterious organization formed to fight paranormal Stains. The main task is to exorcise BOTC-15, an unstable Stain, while using minimal resources. After turning a nearby village into your base, you work with Furina, a powerful exorcist and long-term friend, and command your team through management choices and turn-based combat.

The current build is the v0.13.1b Demo, released September 21, 2026 for Windows, Linux, and Mac, in English, with no censorship. The update lets Hiro be chased when alone, sending him back to town and costing money if caught. It adds a Title System, early with five titles, and new area-effect moves that can be dodged. Some enemies and bosses were reworked. New content includes Furina Window Peep, Furina Goldberg dialogue and CG events, Mansion Faint and Wood Gathering CGs, and a mission to collect wood inside the mansion. Notification fixes, animated elements, better spatial audio, village and UI visuals, upgrades, random names, and an automatic dialogue system are also included.

No idea what everyone is seeing in this, future potential maybe? The game premise is all right, Paranormal activity starts apearing on earth, curse starts spreading around, anomalies spawning, special forces units get created to combat them, Protagonist gets recently…

To keep it brief: The game seems to have potential. You get an idea of what kind of future content it might have. That’s why it’s best to wait a good while longer. You can't really call it a porn…
