Terragenesis - Space Simulator

Build civilizations across distant planets in this space simulator. Terragenesis lets you explore an entire universe, terraform new worlds, and defend humanity from cosmic threats using real science and strategy.

You'll start as a planet crafter with a galaxy full of possibilities. Discover alien life on unexplored worlds, establish thriving civilizations on Mars, Earth, and beyond, and apply NASA-inspired technology to transform barren planets into habitable homes. Each world presents unique environmental challenges—manage resources carefully, adapt your terraforming methods, and watch your settlements grow from empty landscapes into bustling cities.

Defense is just as critical as development. Giant asteroids and alien threats lurk throughout the galaxy, so you'll need to build a planetary defense network to detect incoming dangers. Launch missions to destroy asteroids, alter their trajectories, or devise survival strategies for extinction-level events. The choice between diplomacy, conquest, and coexistence shapes how your civilizations interact with alien species you encounter.

Progress through an expansive universe filled with planets from our solar system and distant star systems. Track your advancement with detailed stats and development summaries, showing how your empire grows across multiple worlds. Each planet you settle brings you closer to securing humanity's future among the stars.

The game is free to download and play. All in-app purchases are optional and never required to experience the full depth of planetary exploration, civilization building, or space defense. Whether you're a casual player enjoying the exploration and world-building mechanics or a strategy enthusiast optimizing resource management and planetary defense, Terragenesis - Space Simulator scales to match your playstyle.
