About This Game

In the distant future, humanity decides to leave a devastated Earth and migrate to Mars.
The massive colony ship is caught in a solar storm and crashes — you must lead the three settlers who escaped in time and build a new home on Mars.

  • On Mars, you can never breathe freely without a suit.
  • Protect your settlers from terrifying sandstorms.
  • Cooperate with other factions to earn their support.
  • Defend your base against hostile factions and seize their resources.
  • Encounter alien factions that show curiosity toward humanity.
  • Reach a variety of endings through research.
  • Uncover the mysteries of Mars unknown to humankind.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some pre-rendered content was created with generative AI tools and then manually reviewed, selected, and edited by the developer: art assets (store capsule artwork, character and environment sprites) and localized text (Japanese, Simplified Chinese, French, and Russian translations of the game's interface). All game design, code, and original Korean/English text were written by the developer. The game does not generate any content with AI at runtime — there is no live or real-time AI generation.
