Alleycat

An open source platform for immersive play

What is Alleycat?

Alleycat is a live, interactive cyberpunk game that transforms strangers into teammates, rivals, and unforgettable characters.

Each year at Neotropolis, hundreds of players step into a world where bounty hunters track fugitives through neon-lit streets using custom-built technology, quick thinking, and a willingness to engage with the people around them. Every challenge, alliance, and rivalry becomes part of a story that can only happen because real people choose to play along.

Whether you're a dedicated roleplayer, a competitive gamer, or someone who's simply curious to see what happens when a city full of strangers is given a reason to interact, Alleycat creates opportunities for meaningful encounters.

The gadgets make people curious.

The game gives them a reason to interact.

The people are what make Alleycat unforgettable.

It's more than a game. It's a community that keeps growing long after the event ends.

Hunt
or be hunted

Every Alleycat story begins with a choice.

Will you become a Bounty Hunter, tracking down fugitives across the neon streets? Or will you volunteer as a Bounty, relying on quick thinking, clever disguises, and fast reflexes to stay one step ahead?

Using custom-built technology, players challenge one another in real-time encounters that encourage competition, collaboration, and unforgettable interactions. Whether you're fully immersed in your character or simply looking for a unique way to meet people, every mission creates opportunities for stories that couldn't happen anywhere else.

One challenge leads to another. One stranger becomes an ally. Before long, you're part of the world yourself.

What’s new in 2026

Every season, Alleycat grows.

This year we introduced the Fixed Data Node (FDN)—a new device that encouraged players to work together by pairing their Portable Data Nodes to unlock hidden information. We introduced multiplayer gameplay with new cooperative and competitive modes, introduced hand-cast Alleycat challenge coins, and recorded over 4,100 player matches across 36 hours of play.

Every year we build new technology, test new ideas, and discover better ways to bring people together.

The 2026 archive tells the story of everything we learned.

Built by makers

We're a team of engineers, artists, programmers, fabricators, storytellers, prop makers, game designers, filmmakers, and relentless problem solvers brought together by one question:

"Wouldn't it be cool if...?"

Every year we design and build the technology, software, game systems, props, and world that power the Alleycat experience. We prototype custom electronics, write thousands of lines of code, and fabricate one-of-a-kind devices. Every piece is designed in-house, tested in the Mojave Desert, broken, rebuilt, and improved for the next season. We develop immersive game mechanics, and lay the groundwork for emergent behavior to evolve.

We're engineers who care about storytelling.

Artists who love technology.

Designers who prototype in code.

Makers who believe the most interesting projects are the ones that bring people together.

If you're the kind of person who likes taking things apart, figuring out how they work, or building something just because it would be awesome to see it exist, you'll fit right in.
