About 687 Days on Mars
687 Days on Mars - about the game
Alone on Mars, you awaken with nothing but your suit and a handful of supplies. Every breath, every drop of water, and every spark of energy must be carefully managed as you fight to survive on a planet that wants you gone - you navigate the harsh realities of life on the Red Planet.
Start small and dream big. Expand your outpost with life-support systems, storage units, and advanced research modules. Every upgrade increases your odds of long-term survival, letting you transform a fragile shelter into a thriving Martian base.
Unlock the secrets of Mars through dedicated research. Develop new technologies to improve your equipment, optimize resource management, and adapt to the planet’s unique challenges. Every breakthrough brings you one step closer to surviving in this environment.
Construct makeshift greenhouses to grow your own food and produce vital oxygen. Using advanced aeroponic and hydroponic methods, you can cultivate plants without soil, overcoming the challenges of Mars. Experiment with different techniques to survive and adapt to the environment.
Leave the safety of your base to explore the vast Martian landscape. Search for previously sent supply drops and unexpected discoveries that could change your fate. Every expedition brings new risks and rewards.
