Command a damaged scout ship in a living space colony survival sim. Wake your crew from cryostasis, secure water and food, build fragile settlements, trade or smuggle between factions, and survive the stories that emerge.
Zenith Expanse
SteamIn 2420, humanity finally reached beyond its home systems. The warp engine opened the way to distant worlds, and the Zenith Expanse program sent small scout vessels ahead of the larger expedition.
Whisper-1 was one of them.
It was not a colony ark. It was a fragile recon ship with a crew of three, enough to scan planets, prepare a first outpost, and prove that life could survive where the maps ended. Then the power failed.
Most supplies were lost. The water recycler contaminated almost everything it touched. Two crew members remain sealed in emergency cryostasis, and the ship AI refuses to wake them until survival projections improve.
Your first job is simple: keep everyone alive long enough to deserve a future.

Zenith Expanse is a single-player space colony survival sim where your expedition begins small, vulnerable, and badly underprepared.

Your colony is not just a base. It is a fragile system of people, supplies, buildings, ships, weather, wildlife, morale, debt, and bad ideas.

Colonists have skills, traits, relationships, needs, injuries, loyalties, grudges, and opinions about your leadership. They can carry the colony through a crisis, make one worse, or quietly become the reason everything still works.

The worlds of Zenith Expanse are not static loot boxes. Planetary ecosystems react to climate, seasons, settlements, migration, food chains, and your interference.

You are not alone in the Expanse. Factions, patrols, settlements, companies, traders, pirates, and political rivalries shape the economy around you.

Zenith Expanse is not about reaching a single victory screen. It is about surviving long enough for your expedition to become a story.
A scout ship becomes a base. A base becomes a colony. A colony becomes a liability, a business, a political actor, a home, or a very expensive mistake.
Keep the crew alive. Wake the sleepers. Build something that can survive the Zenith Expanse.
