PATRICIDE Opens Steam Page, Dark RPG About Girls Who Killed Their Father Launches in December 2026

PATRICIDE is a dark adventure RPG from solo developer Miyoshi Shizuka, previously developed under the title Inner Truth. Its new Steam store page officially opened on September 1, 2026, with the PC release currently planned for December 2026.

Its premise immediately enters heavy territory: girls who killed their father awaken inside a church and encounter the same father who should already be dead. Beneath its story of guilt, trauma, love and hatred, the game combines 3D exploration, action, turn-based combat and an Emotion System that turns empathy into a direct strategic mechanic.

Trailer, Steam and PATRICIDE Gameplay

Inner Truth Becomes PATRICIDE

Miyoshi Shizuka formally announced the project's new name, PATRICIDE, on August 23, 2026.

The developer described the change as difficult after using the previous title for a long time, but also as a necessary step for the project. The new name was considered much clearer in communicating what kind of game it is.

Famitsu provides the thematic connection more explicitly: “patricide” means the killing of one's father, directly linking the title to the story of girls who have killed theirs.

The game's page was also extensively revamped alongside the rename. Its itch.io development history still preserves numerous updates published under Inner Truth before PATRICIDE became the project's official identity.

A Father Who Should Be Dead Returns

Steam introduces Tsubaki and Kocho awakening inside a church.

There they encounter their father again—a man who should already be dead.

The game questions whether the reunion is real or an illusion created by overwhelming guilt and damaged hearts. Finding the answer means unlocking buried memories and confronting the past.

Its social backdrop is intentionally bleak as well. PATRICIDE presents modern Japan as a place where justice can amount to little more than words and responsibility is repeatedly pushed back onto the individual.

The father is therefore not the protagonists' only source of pressure. The society surrounding them contributes directly to the suffocating atmosphere the game is trying to build.

Action and Turn-Based Combat Share One Battle System

PATRICIDE is neither entirely real-time nor a conventional turn-based RPG.

Players can move freely around stages, use cover, reposition themselves and attack from range. At the same time, enemy movement pauses while the player is taking an action.

That creates room to read the battlefield without eliminating direct movement. Positioning, distance and the next action can all be considered at a more tactical pace.

Steam categorizes the game under Action, Adventure, Indie, RPG and Strategy, while its user-defined tags also emphasize Turn-Based Combat, Psychological, Exploration and Party-Based RPG.

The hybrid structure makes it considerably more mechanically active than its dialogue-heavy and anime-styled presentation might initially suggest.

The Emotion System Turns Empathy Into a Mechanic

PATRICIDE's most distinctive system is the Emotion System.

Players can equip an “Emotion,” which changes the character's facial expression and enables them to empathize with feelings such as another person's anger or sadness.

Empathy is not simply a dialogue choice. Breaking through another person's emotional barriers can weaken an enemy or even allow a powerful character to become an ally.

Additional Emotions become available as the story advances, expanding the options players have for different situations.

The system connects PATRICIDE's psychological themes directly with its combat mechanics. Emotional conflict is not confined to cutscenes—it becomes a tool that can affect survival and the balance of a fight.

Exploration Hides Equipment Behind the City's Surface

Outside combat, PATRICIDE includes 3D environments built for exploration.

Characters can squeeze through narrow spaces, climb ladders, pick locks and jump across platforms. Exploring thoroughly can uncover hidden items and equipment.

Dungeon Forge

Steam describes a city whose glittering exterior conceals a concentration of human malice beneath the surface.

Story and battle presentation are also handled differently. Story Mode synchronizes text with detailed camerawork to convey character tension, while Battle Mode uses stylish cut-ins when special moves are activated.

The itch.io page lists Unity, Blender and Clip Studio Paint among the tools used for development, and it explicitly states that no generative AI was used for the game's content.

Steam Page Passes 1,000 Wishlists With Next Fest Demo Ahead

PATRICIDE's Steam page opened on September 1, 2026.

Only a few days later, Miyoshi Shizuka announced that it had surpassed 1,000 wishlists on September 4.

The next major step is Steam Next Fest. The Japanese press release carried by Famitsu lists October 20–27, 2026, with a Steam demo planned during the event.

Players do not have to wait until then to try a development build. Version 2.9.0 Demo is already available through itch.io as an approximately 2.4 GB download, adding features such as a Father Conversation Event at the Summer Festival, Dialogue Mode fast-forward and Help.

The full Steam release remains targeted for December 2026. A specific day has not been announced, and ¥2,530 remains a planned sale price from the press release rather than a currently active Steam purchase price.

Why This Matters

1) The new title immediately communicates the core conflict

PATRICIDE has a much more specific meaning than Inner Truth and directly points toward the protagonists' relationship with their father.

2) Empathy is more than a narrative theme

The Emotion System turns emotional states into mechanics that can weaken enemies or potentially turn characters into allies.

3) Combat tries to bridge action and strategy

Players still navigate a 3D battlefield directly, while pausing enemy movement during player actions creates time for tactical decisions.

4) The solo-developed project continues to evolve through public demos

PATRICIDE has a long history of public development builds on itch.io and is now moving toward broader exposure through Steam and Next Fest.
