Maximilien — A Psychological Horror Interactive Novel

An Uneasy Awakening in Boston

Maximilien — A Psychological Horror Interactive Novel plunges you into the unsettling world of 1926 Boston. Here, you assume the role of Maximilien Cornwell, a psychology student grappling with his own fragmented past while a notorious serial killer, the Ogre of South Boston, haunts the city's streets. The narrative blurs the line between reality and madness, inviting players to explore not just the city but the labyrinth of the mind.

A Deeply Layered Narrative Experience

With over 500 passages and 1,755 conditional story states, the branching narrative promises a rich exploration of character and choice. Each of the four distinct routes offers a unique perspective on the intertwining mysteries, culminating in eight different endings. Players will discover that the paths reveal not only the motivations of others but also the shadows lurking within Maximilien himself.

Investigation Mechanics Designed for Tension

The game incorporates a real investigation system, where players piece together clues and explore a hand-drawn map of Boston. Your discoveries will shape how you interpret events and engage with the world around you. Balancing time against limited actions under the pressure of a police investigation adds layers of tension, forcing decisions that carry real consequences.

Mental Health: A Crucial Element

Maximilien's journey isn't solely an external quest; it delves deep into the psyche. Unique mental health mechanics affect the player's perception of reality, with sanity influencing what clues are visible and how choices are presented. The struggle against inner demons heightens the horror, making each decision feel weighty and impactful.

A City Steeped in Atmosphere

The setting of 1920s Boston serves as a character in itself, shadowed by occultism and secrets. From prohibition-era streets to hidden alleys, the ambiance invites exploration. The dense, literary writing style resonates with echoes of Lovecraft and Poe, crafting a slow-burn dread that is psychologically unsettling rather than reliant on graphic horror.

Creating with Passion and Precision

Behind this deep narrative is Yohan Dupuy, who dedicated seven years to crafting and researching Maximilien. Extensive research into actual criminal cases helped shape the game’s authenticity, infusing it with historical depth. The writing is exclusively human-crafted, making Maximilien a testament to the enduring power of storytelling in interactive media.

Timed Release and Accessibility

Set to launch on October 26, 2026, Maximilien will be available on PC, compatible with both Windows and Linux, with an Android version to follow. Featuring English and French language options, the game emphasizes accessibility without compromising its complex themes or narrative style. With an estimated playtime of 4–6 hours per route, it invites exploration and contemplation.

A Caution for the Night Owls

Prepare for a gripping tale that won't shy away from darkness. Players should note the content warnings for psychological horror, themes of dissociation and mental illness, and non-graphic depictions of criminal violence. As the investigation unfolds, tread carefully, for Maximilien is a game best approached under the light of day—or not at all.
