Stranded on the Moon.
Without memory.
With limited oxygen.
Deep beneath the surface, an astronaut encounters an alien world.
Alive. Deadly.
Bound by rules no one explains.
In the remnants of a non-human intelligence, he finds an artifact.
A sphere of unknown origin, whose behavior does not seem random.
It is not a tool.
Not a weapon.
But it responds to decisions.
Every resource is limited.
Every mistake has consequences.

Deep Moon I - Artifact blends atmospheric survival science fiction with first contact and consequence-driven decision dynamics. Intense. Uncompromising. High-tension.
