Overview

About this game

Prologue:

In 2015, the Kepler radio telescope discovered the exoplanet K2-18b. In 2023, dimethyl sulfide molecules were detected in the planet's atmosphere, and in 2025, the presence of biosignatures was confirmed.

In 2027, a radio signal of clearly artificial origin was received from the K2-18 star system. In 2036, the home planet was engulfed in a humanitarian crisis, and two years later, the Ark Initiative was created. Initiative scientists managed to decipher the transmitted signal: it contained detailed instructions for creating instantaneous mass displacement in space. In 2047, a decision will be made to launch an expedition to K2-18b.

2057. As part of the Ark Initiative, you join the expedition to planet K2-18b. You don't plan to be a pioneer, but unexpected difficulties arose during landing...
