In the distant future, our civilization, spread throughout the solar system, relies on a Solar Lift for power. Through neglect (or sabotage) the Lift is now failing, and our very survival is at risk! In Helionox - the Last Sunset, a sci-fi deck-building strategy game, terrible events plague the solar system as the result of a dying sun. As Architects of the Future, players vie for influence among the remaining populace. Craft your deck with powerful faction cards, explore and exploit the system's worlds, and gain the most influence so you can lead civilization to a new beginning in the wake of the Helionox.
