Compare Zarya-1: Mystery on the Moon prices across trusted key stores and find the best deal. Developed by Your Story Interactive. Published by Your Story Interactive. Released on 5/30/2017. Available on PC, Mac, Linux. Genres: Adventure, Indie.

A short, quiet horror story told entirely through chat logs and lunar photographs - perfect for readers who want their sci-fi with real weight, less so for anyone expecting to feel like they're actually piloting something.

I have a soft spot for games that trust words to do the heavy lifting, and Zarya-1 is almost entirely made of them. You sit at a mission control terminal, communicating with a four-person crew who have been dispatched to the far side of the Moon after Earth picks up a mysterious signal. The whole thing unfolds like an intercepted radio drama: dialogue streams in, tension climbs, and every few minutes you get to choose between two or three possible commands or comments to issue to your team. That is the loop. If you can settle into it, there is something genuinely unsettling here. The writing is the clearest reason to show up. The crew members have distinct voices, the banter feels lived-in, and the hard-science texture - low gravity, suit temperature management, the specific physics of operating in a vacuum - gives the horror a grounded quality that most budget interactive fiction skips entirely. Atmosphere is built through music that shifts register as danger approaches, plus a handful of still photographs the team transmits back to base. Those images arrive through a slow enhancement animation that community players have flagged as unskippable and repetitive - a legitimate friction point worth knowing before you commit. The branching structure is where Zarya-1 gets complicated. There are multiple endings, and the rewind-and-retry mechanic lets you roll back to earlier chapters when things go wrong. The problem is that consequence feels opaque. Some choices kill crew members without obvious foreshadowing, and the single full-success path reportedly requires decisions that read as arbitrary on a first run. Players who approach this looking for a solvable puzzle will hit a wall; players who read it more like a branching short story, curious about what each path reveals rather than hunting for the optimal outcome, tend to come away far warmer on it. For what it is - a lean, atmosphere-first interactive fiction piece sitting well below five dollars - Zarya-1 earns its place. The Mac version carries a compatibility warning for macOS Catalina and above, so check that before you buy if you are on Apple hardware. No voice acting, no DLC, no multiplayer. Just a distress signal, four people you will probably get killed at least once, and writing that respects the loneliness of space in a way most bigger games do not bother with. Come for the mood, not the mechanics. Kai, Scout Team

GamerScout Verdict

Worth it for readers who want sci-fi horror told in words - skip it if you need agency that feels mechanically fair.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
