Spores, Steel, and Social Strife: The Emergence of ‘Signet City’

The landscape of indie narrative RPGs is set for a profound transformation. During the highly anticipated PC Gaming Show 2026, publisher Fellow Traveller and solo developer Jump Over The Age—the creative force behind the critically acclaimed Citizen Sleeper series—lifted the veil on their latest project: Signet City. Billed as a "fungalpunk" RPG, the game promises a haunting, monochromatic descent into a coastal metropolis where biological mutation and industrial decay collide.

As the developer’s first major project following their celebrated sci-fi duology, Signet City is already positioning itself as a benchmark for atmospheric storytelling and innovative, mechanics-driven narrative design.

The Core Premise: A Parasite’s Perspective

At its heart, Signet City subverts the traditional "hero" archetype. Players do not inhabit a traditional protagonist; instead, they take on the role of an unnamed, sentient fungal parasite. This entity does not merely exist within the city—it actively infiltrates the social and biological fabric of the urban environment.

The gameplay loop revolves around a unique symbiotic relationship. By infecting the residents of Signet City, players gain access to the minds and memories of their hosts. This first-person perspective allows for a granular, intimate exploration of the city’s populace. Using a sophisticated suite of tabletop-inspired mechanics, players must navigate the emotional landscape of their hosts. These internal states—fear, desire, desperation, and hope—directly influence the trajectory of the narrative, allowing players to manipulate the city’s history, politics, and fate.

The developers describe the city as a "mirror and distortion" of our own reality. Set against a backdrop of rising tides and governmental overreach, the game explores the familiar, grinding friction of modern labor and power structures, albeit through the surreal lens of a rapidly mutating fungal outbreak.

A Chronology of Development: From Starward Vectors to Spore-Choked Streets

The journey to Signet City follows the meteoric rise of Gareth Damian Martin, the solo developer operating under the Jump Over The Age moniker.

• The Citizen Sleeper Era (2022–2025): Martin established a reputation for weaving complex, choice-driven narratives that emphasize community, identity, and the precarity of life in space-faring societies. The success of Citizen Sleeper and its sequel, Citizen Sleeper 2: Starward Vector, set a high bar for emotional depth and mechanical integration.
• The Transition (Late 2025): Following the completion of the Citizen Sleeper cycle, rumors began to circulate regarding Martin’s next pivot. Fans noted a shift in the developer’s social media aesthetic, moving away from the bright, neon-drenched palettes of sci-fi toward a more austere, monochromatic visual language.
• The Reveal (June 2026): Signet City was officially unveiled during the PC Gaming Show 2026. The announcement trailer, set to the raw, pulsating rhythm of Irish punk band SPRINTS’ track "Abandon," immediately set the tone for the game’s aesthetic—a marriage of 1980s post-punk gloom and organic, sprawling fungal growth.

Aesthetic Philosophy: Drowned in Ink and Grain

One of the most striking elements of Signet City is its visual presentation. Moving away from the vibrant, high-contrast UI of their previous work, Jump Over The Age has opted for a stark, monochromatic aesthetic.

The game’s visual identity is deeply indebted to diverse artistic traditions:

• Black and White Documentary Photography: The city captures the grit of the UK’s industrial North during the 1980s, evoking the feeling of a world captured in film stock.
• Manga and Pen-and-Ink: The use of screen-toning and cross-hatching gives the environments a hand-drawn, tactile quality that feels both timeless and unsettling.
• Post-Punk Fever Dream: The design philosophy is rooted in the "underground culture" that inspired the game. The visual language mirrors the chaotic, defiant energy of the 80s, creating a world that feels as though it is decaying and evolving simultaneously.

Official Commentary and The Role of Sound

The collaboration between Fellow Traveller and Jump Over The Age has been characterized by a shared commitment to thematic cohesion. The choice of the track "Abandon" by SPRINTS was not an incidental creative decision but a deliberate alignment with the game’s core ethos.

In a formal press release, the publisher noted, "The music was chosen specifically because it is rooted in the same underground culture that serves as the bedrock for the game’s philosophy. It is a reflection of the tension, the struggle, and the raw humanity that players will encounter in every street corner of Signet City."

This dedication to sound and tone underscores the "fungalpunk" label. The term itself is a commentary on the setting: a place where "fungal systems shape the philosophy, politics, visual language, and social structure of the world." The fungi are not merely an environmental hazard; they are the catalyst for a radical, if terrifying, societal shift.

Mechanical Implications: Tabletop Roots

For veterans of Citizen Sleeper, the move toward "tabletop mechanics" will feel familiar yet refined. In Signet City, these mechanics serve as a bridge between the parasite and the host.

When a player occupies a character, they are not just controlling an avatar; they are managing the character’s psyche. A host’s emotional state—affected by the mounting pressures of their crumbling city—serves as a modifier for the player’s agency. If a host is terrified, the parasite’s ability to influence the city’s infrastructure or political outcomes becomes constrained or volatile.

This creates a high-stakes balancing act. Does the player force a host to make a choice that benefits the parasite’s long-term goals at the risk of destroying the host’s mental stability? Or does the player act as a silent observer, allowing the city’s natural, albeit tragic, history to unfold? These ethical dilemmas are central to the game’s design, forcing players to grapple with the morality of agency in a world defined by systemic collapse.

The Significance of the "Fungalpunk" Genre

While "cyberpunk" has long dominated the discourse of industrial dystopias, "fungalpunk" offers a biological, organic alternative. It shifts the focus from the artificial to the natural—specifically, the resilience and terrifying adaptability of nature in the face of human hubris.

Signet City positions the environment as an active participant in the story. As the waters rise and the city’s infrastructure fails, the mycelium networks thrive. This ecological crisis serves as a poignant, if dark, reflection of our own contemporary anxieties regarding climate change, labor exploitation, and the loss of individual agency in an era of massive, impersonal systems.

Looking Forward: A City in Waiting

As of this writing, Signet City does not have an official release date. It is currently in development for Windows PC via Steam. While this may leave many eager fans waiting, the precedent set by Gareth Damian Martin’s previous work suggests that the wait will be justified.

The game represents a bold departure from traditional RPG structures, moving toward a more abstract, atmospheric, and deeply philosophical experience. By blending the mechanics of tabletop gaming with a narrative that demands constant ethical evaluation, Signet City is poised to be more than just a game; it is an exploration of what it means to be alive, connected, and influential in a world that is slowly turning into something entirely new.

For those tracking the evolution of the genre, Signet City is a title that cannot be ignored. It captures the spirit of an era—the 1980s—while projecting it into a future that feels all too plausible. Stay tuned to RPGFan as we continue to track the development of this haunting, ink-stained masterpiece. In the coming months, we expect further insights into the specific character systems, the nature of the parasite’s endgame, and the further expansion of the "fungalpunk" lexicon. One thing is certain: the city is calling, and its secrets are beginning to bloom.
