Evaluation

Zarya-1: Mystery on the Moon launched on May 30, 2017 as a self-contained narrative text adventure. The store description presents it as a complete story with multiple endings and a rewind feature — all hallmarks of a finished, packaged experience with no expectation of ongoing content. There are no DLC listings, no post-launch update announcements, no developer roadmaps, and no news posts signaling any planned additions. The two developer news posts on record contain no content-relevant information. With nearly nine years having passed since launch and no post-launch content activity of any kind, this game clearly shipped as a finished product and has remained so.

Adventure Indie Text-Based Sci-fi Horror Space Choose Your Own Adventure

About this game

Zarya - 1 is a survival text based quest with elements of science fiction, horror, and occasional humor. In this game you will be able to alter the story by making choices, creating your very own adventure.

If you liked Alien, Dead Space and Lifeline - you'll love this.

THE STORY.

In 2021 humankind received a distress signal from the far side of the Moon, and immediately sent four brave people to investigate its source. You will be monitoring the astronauts and make decisions that will directly impact the story and the characters. Each choice may lead you closer to - or farther from - the truth.

FEATURES

Mind-shattering atmosphere, a mix of sci-fi and horror in the veins of Alien and Prometheus, spiced up with the occasional joke
Communicate with the astronauts in real time
Influence the story by making your own decisions
There are multiple endings, including happy ones :)
You can rewind the story and make another choice if the mission ends in a disaster
What separates this game from other text quests like Lifeline, are the awesome photos that the team sends your way while exploring the source of the signal
