Shueisha Games to Publish NIGHTMARE OPERATOR, Miyuki Sawashiro Voicing Misha

Katsu Somehira, the illustrator behind the key visual, has drawn cover art for the manga magazine Harta, published by KADOKAWA. The visual shows Misha and a powerful enemy standing in her way.

The story has a named antagonist and a named incident. The anti-government organization Twilight Blade carries out a terrorist attack in the quarantine city Shin-Chiba, and Misha is tasked with finding the mastermind. That trail leads to Twilight Blade's mysterious commander, Tsukuyomi Ken, and into a case built on conspiracy, sacrifice, and betrayal.

The setting draws on real Tokyo. The low-polygon world is based on existing streets and landmarks, and locations in the game are modeled on actual Tokyo streets. The yokai come from urban legends and Japanese folklore, but their forms depart from the legendary versions.

Combat details beyond the base systems:

• Weapon modules can inflict status ailments including freeze, stun, and bleeding.
• Weapon programs tune the gun: one vents heat when a melee attack lands, another raises the rifle module's rate of fire the longer the trigger is held.
• Modules are found while exploring the map and equipped into the Modular Gun's command slots.
• Module types range from rapid-fire to shotgun to sniper.
• At the outpost izakaya, drinking parties with companions fill in the history of the game's world.
