Fungal Decay and Post-Punk Dreams: Unveiling Jump Over The Age’s ‘Signet City’

The landscape of independent narrative RPGs is about to undergo a radical, spore-laden transformation. During the highly anticipated PC Gaming Show 2026, developer Jump Over The Age—the singular creative force behind the critically acclaimed Citizen Sleeper series—unveiled his latest project: Signet City.

Described as a "fungalpunk" RPG, the game promises to meld the intimate, choice-driven mechanics of tabletop roleplaying with a haunting, monochrome aesthetic that evokes the grimy, industrial reality of 1980s Northern England. As the trailer debuted, set to the aggressive, driving pulse of the Irish punk band SPRINTS’ track "Abandon," it became clear that Signet City is not merely a game about survival, but a deep-dive into the intersection of ecology, labor, and the decay of power.

The Genesis of a Mycelial Metropolis: Main Facts

Signet City is currently in active development for Windows PC via Steam. At its core, the game challenges the traditional conventions of the RPG genre by placing the player in an unprecedented role: you are not a human protagonist, but an unnamed, pervasive fungal parasite.

As this entity, the player navigates the titular coastal city of Signet, a location teetering on the edge of collapse. The gameplay involves a delicate dance between infecting the local populace and influencing the minds of those who act as your unwitting hosts. By utilizing tabletop-inspired mechanics, players must weigh the emotions and psychological states of their hosts against the grander, often brutal, history of the city.

The developer, Gareth Damian Martin, has explicitly designed the game to act as a mirror to our own world. Through the lens of a "fungalpunk" setting, Signet City examines the systemic pressures of the modern era—labor exploitation, governmental overreach, and the looming shadow of ecological crisis—distorting them into a narrative experience that feels both alien and uncomfortably familiar.

A Chronology of Anticipation: From ‘Citizen Sleeper’ to ‘Signet City’

To understand the weight of the Signet City announcement, one must look at the trajectory of Jump Over The Age. Gareth Damian Martin established his reputation for narrative excellence through the Citizen Sleeper duology, a series that redefined how games handle systemic vulnerability and personal autonomy in sci-fi settings.

• 2022: The release of Citizen Sleeper set a new benchmark for narrative-heavy RPGs. Its focus on internal struggle, community building, and the precariousness of life under corporate hegemony resonated with players and critics alike.
• 2025: The sequel, Citizen Sleeper 2: Starward Vector, expanded the scope of the world, further refining the tabletop-infused dice mechanics that have become a hallmark of Martin’s design philosophy.
• 2026 (June): The reveal of Signet City at the PC Gaming Show confirms that Martin is moving away from the stars of the Erlin’s Eye space station and toward the damp, ink-stained streets of a terrestrial, yet mutated, urban landscape.

The transition from the digital neon of Citizen Sleeper to the "drowned in ink" monochrome of Signet City suggests a creator who is interested in testing the elasticity of his own mechanical frameworks. While the dice may be different, the commitment to "narrative weight"—where every choice feels like a pivotal day in a life—remains the central pillar of the design.

Supporting Data: The Fungalpunk Aesthetic and Mechanics

The visual language of Signet City is one of its most striking features. Drawing heavily from black-and-white documentary photography, the intricate lines of pen-and-ink drawings, and the high-contrast aesthetic of screentoned manga, the game creates a sense of place that is both claustrophobic and beautiful.

The Philosophy of the Spore

The "fungal" aspect of the game is not merely a thematic skin; it is a mechanical necessity. The developer has noted that in Signet City, fungal systems dictate everything from the city’s political philosophy to its visual architecture. By playing as a parasite, the player is forced to confront the ethics of host manipulation. You are not a hero saving the city; you are an invasive force that may be the only thing capable of changing its tragic trajectory.

The 1980s Fever Dream

The 1980s in the United Kingdom were a period of immense social and industrial transition, characterized by labor strikes, the decline of manufacturing, and the rise of post-punk as a cultural outlet. Signet City captures this specific "dark dream," using the aesthetic of industrial northern cities to ground its fantastical elements. This choice of setting acts as a powerful metaphor for the "rising waters" mentioned in the game’s promotional material—a nod to both the physical threat of flooding and the rising tide of societal instability.

Official Responses and Creative Intent

In a press release issued alongside the trailer, the publisher, Fellow Traveller, provided context for the collaboration and the music choice. "The song ‘Abandon’ by SPRINTS was selected because it is rooted in the same underground culture that inspires the game," the publisher stated. This connection to the punk ethos is vital; it signals that Signet City is designed to be a rebellious, gritty, and raw experience that rejects the polished, corporate sheen of many modern titles.

Gareth Damian Martin’s design philosophy for this title centers on the "First Person Fungalpunk" perspective. By going "behind the eyes" of his hosts, Martin intends to blur the lines between the player’s agency and the character’s autonomy. In interviews, he has emphasized that the game is about "seeding stories" within a landscape that is actively resisting change. The city is in a vortex of crises, and the player is the catalyst that could either accelerate the destruction or facilitate a strange, new form of growth.

Implications: The Future of Narrative RPGs

The announcement of Signet City has significant implications for the indie RPG space.

1. Mechanical Evolution: If Citizen Sleeper proved that tabletop mechanics could work in a digital medium, Signet City appears poised to prove that these mechanics can be adapted for increasingly complex, character-driven psychological dramas rather than just traditional quest structures.
2. Visual Storytelling: The commitment to a purely monochrome, ink-based art style is a bold departure from the vibrant, high-fidelity graphics common in the industry. It suggests a trend toward "artistic intentionality" over technical realism, where the game’s look is a direct extension of its narrative themes.
3. Sociopolitical Commentary: By framing the game around labor, power, and ecological collapse, Jump Over The Age is cementing his role as a developer who is unafraid to tackle the heavy, systemic issues of the modern day. Signet City is likely to be a game that invites intense discussion, not just about its gameplay loops, but about the real-world anxieties it mirrors.

As we look toward the release of Signet City, the lack of a definitive date is perhaps a blessing. It allows for the slow, deliberate cultivation of a world that seems to thrive in the dark, damp, and forgotten corners of human civilization. With the foundation of Citizen Sleeper behind him and a bold new artistic vision in front of him, Gareth Damian Martin is positioning Signet City to be one of the most intellectually stimulating games of the coming years.

For those who enjoy narrative-heavy experiences that value player choice, thematic depth, and a unique visual identity, Signet City is a title that demands your attention. As the spores settle and the city begins to reveal its secrets, one thing is certain: the landscape of the RPG genre is changing, and it is doing so with a dark, monochrome beauty that is impossible to ignore. Stay tuned as more details emerge regarding this upcoming journey into the heart of a decaying, living city.
