Shueisha Games has announced that it will publish NIGHTMARE OPERATOR, an upcoming third-person action-horror shooter developed by DDDistortion for PC via Steam. The publisher confirmed the partnership on November 10, 2026, alongside a new teaser trailer, promotional artwork and additional details about the game’s combat systems and supernatural setting. A release date has not been announced.
The announcement also confirms that Japanese voice actress Miyuki Sawashiro will portray protagonist Misha, whose voice is featured in the new teaser. The footage highlights fast-paced combat against supernatural enemies and the game’s distinctive low-polygon visual style.
Set in a devastated version of Tokyo in 2036, NIGHTMARE OPERATOR combines third-person shooting with fighting game-inspired mechanics, customizable weapons and enemies drawn from Japanese folklore.
Players control Misha, a Public Safety Operator working for a provisional government after humanity has been pushed toward extinction. She survives by eliminating supernatural creatures known as Yokai from the ruins of Tokyo.
Her routine changes when an anti-government organization called Tasogare-no-Yaiba carries out a terrorist attack in the quarantined city of Shin-Chiba. Assigned to investigate the incident, Misha pursues the organization’s mysterious commander and becomes entangled in a conspiracy involving human sacrifice and betrayal.
The game’s environment recreates recognizable Tokyo districts and landmarks through a retro-inspired, low-polygon aesthetic. Its supernatural enemies take inspiration from Japanese urban legends and folklore, with different creatures displaying distinct behavior. Some attack aggressively like wild animals, while others coordinate their movements and employ more deliberate tactics.
Combat centers on a customizable firearm called the Modular Gun, which allows players to equip different weapon modules and switch between them during encounters.
One module functions as a railgun capable of inflicting status effects such as stun and freeze. Another transforms the weapon into a stake launcher that impales enemies and inflicts continuous damage.
The Modular Gun’s Clutch System uses command inputs inspired by fighting games, allowing players to rapidly change weapon configurations and combine attacks into consecutive sequences. Rather than relying entirely on conventional shooting, players must manage weapon selection and timing while responding to different enemy behaviors.
However, the system includes an overheating mechanic that limits sustained attacks. Repeatedly firing the Modular Gun increases its heat gauge, eventually triggering an overheat that leaves Misha vulnerable for several seconds.
Players must therefore balance aggressive combinations against the risk of temporarily losing access to their weapon.
NIGHTMARE OPERATOR also features Weapon Programs, which modify the Modular Gun’s performance and allow players to tailor its capabilities to different combat styles.
Some programs help manage overheating by releasing accumulated heat after successful melee attacks. Others alter individual weapon modules, including an upgrade that increases a rifle module’s firing speed the longer the trigger is held.
Between missions, Misha can return to the Sumida Reclamation Outpost, a surviving human settlement within Tokyo’s ruins. The location allows players to purchase new weapon modules, upgrade their equipment and practice at a shooting range.
Players can also interact with other operators and residents to learn more about the setting and the events surrounding the Yokai crisis.
The combination of supernatural combat and stylized environments places NIGHTMARE OPERATOR alongside other indie action-horror titles, including Silly Polly Beast, which also blends horror themes with action-focused gameplay.
The November 10 announcement establishes Shueisha Games as NIGHTMARE OPERATOR’s publisher and introduces its latest promotional trailer rather than marking the game’s original reveal.
NIGHTMARE OPERATOR remains in development for PC through Steam. Shueisha Games and DDDistortion have not announced a release date or confirmed additional platforms.
