About the Game
See the Red Planet like never before, land for the first time all over again, and discover some brand-new secrets.
Welcome home! The award-winning sci-fi city builder is back - remastered, expanded, and more stunning than ever. Your mission: colonize Mars and survive the process, from exploration and infrastructure to welcoming human colonists and achieving long-term stability. There are new challenges to overcome, new strategies to plan, and now with an upgraded look and feel for a new generation of explorers.
All you need for this relaunched mission to create a thriving Martian settlement is a steady supply of resources, oxygen, decades of training, experience with sandstorms… and a curious attitude to discover the purpose of those weird black cubes that appeared out of nowhere. With a bit of sprucing up, this place is going to be awesome!
Surviving Mars: Relaunched brings together the original colony management game from Haemimont Games, its entire catalogue of expansions, improved and reworked, from major expansions to cosmetics and radio stations, as well as the all-new Martian Assembly update. Upgraded graphics together with updated UI will give veteran players the definitive Surviving Mars experience, and provide an ideal launch point for new commanders as well.
Are you ready? Mars is waiting for you.

The new Martian Assembly brings an expanded endgame challenge never seen in the original. Shape your Martian society through laws. Balance the needs and demands of your colonists, keep the peace and develop a long-term plan for Mars - up to and including independence from Earth!

Building a thriving colony on a planet not fit for human life brings its own challenges. Construct life-support systems, power grids, domes, and supply chains, and keep them running, because blackouts on a planet without oxygen are never a good idea. And you’re not alone. With the included ‘Space Race’ expansion, rival colonies backed by competing sponsors add even more pressure as you fight for resources and the future of Mars.

Balance critical resources like oxygen, water, power, and food to keep your colony alive. Drones build and maintain your infrastructure, while the revamped ‘Martian Express’ adds trains that move people and supplies across longer distances. Every colonist has their own needs and behaviors and smart management is essential for their survival.

Advance your colony through a deep research system that unlocks new buildings, production methods, and essential upgrades. Discover breakthroughs, resources, and hidden secrets reaching ‘Below & Beyond’ the Martian surface. With randomized maps, varied sponsors, and unpredictable Mysteries, every playthrough offers new challenges, and every decision shapes your story of survival and growth on Mars.

Terraforming is no longer a distant dream, it’s your next challenge. With the included ‘Green Planet’ expansion, you can engineer Mars into a more habitable world. As the environment transforms, introduce animal life with ‘Project Laika’, bringing the first creatures to thrive alongside your colonists. The future of Mars isn’t just survival, it’s building a self-sustaining, living planet.

Hello Commander,
A hotfix has just landed, addressing issues you have been reporting. We’re actively monitoring your feedback and will continue working on additional fixes and improvements in the days ahead.
Asteroid / Waste Rock Issue
We’ve implemented a temporary workaround to address the most severe issues currently affecting the asteroid / waste rock collection. This is a band-aid solution to get this fix to you immediately and you will need to manually initiate the asteroid lander launch.
We’re actively working on a permanent, more robust fix that will restore the intended functionality, but to not delay the patch this is a fix we could implement quickly with low risk.
Inspiring Architecture tech causing Game Freeze
This patch fixes the game freeze issue caused by the Inspiring Architecture tech. If you are playing on a save that have researched the Inspiring Architecture before this patch, you may unfortunately continue to have issues with your colonists due to them having been initialized in a broken state, to fully resolve this you need to either:
Start a new game,
Load a save from before researching Inspiring Architecture, or
Allow the broken colonists to naturally “expire.”
Thank you for your feedback and patience while we continue improving the experience.
Change Log:
Asteroids
Asteroid Lander no longer loads waste rock.
Asteroid Landers will now depart only after an explicit Liftoff order (unless its an Evacuation due to an asteroid expiring) and will no longer automatically return to the asteroid without user input.

Fixed an issue where an Asteroid Lander would sometimes confuse its destination and land where it departed from.
