Xenolanguage - Starter guide
What is Xenolanguage?
Xenolanguage is a storytelling game about first contact, told through the slow, uncertain work of learning to understand a language that was never meant for human minds. You play scientists bound together by a shared past and unresolved tension between them, tasked with deciphering an alien intelligence's messages. As the meaning of the alien language comes into focus, so does something about the characters themselves, the game is as much about the people at the table as it is about the aliens they are trying to reach.
It comes from Thorny Games, the studio behind Dialect, and is the designers' third game built around language, following Dialect and the earlier free release Sign. Created by linguists Kathryn Hymes and Hakan Seyalioglu, Xenolanguage was funded on Kickstarter and released in 2024, drawing explicit inspiration from Arrival, the Ted Chiang novella Story of Your Life it is based on, Contact, and Interstellar, soulful science fiction where communication itself is the story.
How does the system work?
Play centers on the Platform, a custom channeling board printed with thirty alien symbols. Using a planchette-like Lens, players move together across the board to receive fragments of the alien's communication, closer to a Ouija board in feel than a traditional game piece. A Story deck supplies prompts that surface the scientists' shared history, and included digital soundscapes set the atmosphere for each session.
Like Dialect, the game is entirely GM-less and diceless: there is no referee and no random chance, only the table negotiating meaning together as symbols are uncovered. But where Dialect builds a language from a community's own words as it dies, Xenolanguage works in reverse, decoding a language that already exists and was never made for you, while the characters' personal history unfolds in parallel with what they learn.
What do you need to start?
Everything ships in one box: the Platform board, the Lens, the Story deck, and the digital soundscapes. Three to five players and three to four hours are all a table needs, there is no GM to prepare and no supplementary material required beyond what comes with the game.
Who is this game for?
Xenolanguage suits groups drawn to atmospheric, character-driven science fiction in the vein of Arrival, players who want a first-contact story built around wonder and uncertainty rather than conflict or action. The tactile ritual of moving the Lens across the Platform together is part of the experience itself, groups who enjoy a bit of ceremony at the table will find it adds real weight to each session.
It is a poor fit for players looking for combat, dice-driven stakes, or hard science-fiction procedure. And because meaning here is built entirely through negotiation between players rather than resolved by any system, quieter groups may find it asks more of everyone than a traditional GM-led game would.
How does it compare to other systems?
Against Dungeons & Dragons 5e, there is almost no overlap: no combat, no character sheets, no GM directing the plot. The story exists only because the players build it together, symbol by symbol.
The closest relative by far is Dialect, built by the same designers on the same philosophy. Both are GM-less, card-and-prop-driven games about the negotiation of meaning, but Dialect watches a human language die inside an isolated community, while Xenolanguage watches an alien one come into focus for the first time. If one appealed to you, the other is very likely to as well, just pointed in the opposite direction.
Where do you start?
Set aside time to calibrate the mood before you start decoding symbols: dim the lights, run the included soundscapes, and let the Story deck establish who these scientists are to each other before the alien communication becomes the focus. The tactile setup is not a formality, it does real work in setting the tone.
One piece of advice: resist the urge to solve the alien language quickly. The game rewards patience and uncertainty; meanings that come too easily tend to flatten the sense of genuine first contact the whole experience is built around.

Xenolanguage is complete in one box, nothing else is required to play. If the idea of building meaning together across a language barrier is what drew you in, our Dialect starter guide covers the sibling game that started it all, same designers, same GM-less philosophy, aimed at a dying human tongue instead of an alien one. And if the GM-less, collaborative format is the main draw, our The Quiet Year starter guide covers another game built entirely around a table shaping a story together without anyone in charge.
