About Alien Horizon (Preview Alpha)
Alien Horizon is a sci-fi survival city builder set on an inhospitable alien planet.
Faced with imminent destruction of Earth, humanity pooled together their resources and sent sleeper ships to nearby potentially habitable planets. But this one turned out to be much less habitable than expected. Can you survive anyway?
Build your colony around the sleeper ship, containing 1000 last survivors from Earth. Construct power sources, housing, infrastructure and factories to ensure comfort of your colonists and provide the colony with all the resources it needs. Manage bus lines, set laws and provide services, making sure your colonists are happy, healthy and productive. Each colonist is their own simulated individual.
Earth is dead, so it can't help you out here. If you didn't bring something with you, tough luck. Explore the landscape around you to find all the other ships from your fleet that carry supplies, and survey resource deposits to eventually produce your own.
Manage complex production chains to produce 86 different resources, each with a realistic recipe. Build logistics hubs and set up storages to make sure all of them get to where they need.
Even though this is a free preview, it's a full-fledged game of its own, with no time or content limitations. It is possible to achieve a self-sufficient colony. The proper game is still in development and will be released later. You can support its development by buying the Donation packs.

Great game that I expect to loose many, many more hours to when the rewrite is complete.
the best scifi colony builder ive ever played. although calling it "scifi" might do it injustice, as the mechanics and components are so realistic and believable, it might just be "mars colony training simulator". great art style, great pacing, just love it!
Alien Horizon Preview Alpha is an ambitious colony-building and survival management game developed and published by Purple Nebula. Set in a future where humanity is forced to abandon a doomed Earth, the game begins with a desperate mission to establish a new home on a distant alien planet. What initially appears to be a promising refuge quickly reveals itself as a harsh and unforgiving environment, forcing players to overcome countless challenges if they hope to secure humanity’s future. The premise creates a strong sense of responsibility from the outset, as every decision directly impacts the survival of thousands of colonists depending on the success of the settlement. The core gameplay revolves around constructing and expanding a functioning colony capable of supporting a growing population. Players start with limited resources and a group of settlers emerging from cryogenic sleep, then gradually build housing, power infrastructure, industrial facilities, transportation systems, and essential public services. Unlike many city builders that focus primarily on expansion, Alien Horizon places considerable emphasis on sustainability. Every building, production chain, and resource …

A peaceful building game which gets satisfyingly complex. If you like managing things, being efficient, and building sims, this is lovely.
