Mars Horizon

Lead a major space agency as you guide humanity to Mars. Construct a base, design and build rockets, conduct missions throughout the Solar System, and write your own history of Space exploration. Created with support from the European Space Agency.

Mars Horizon

In Mars Horizon, you take control of a major space agency, leading it from the dawn of the space age through to landing astronauts on Mars. Guide your agency through the space race and write your alternate history of space travel - any of the agencies can be the first to land on The Moon if you make the right choices. You’re in charge of every element of the journey into space: success rides on your decisions.
Manage the numerous challenges faced then and now:
  • Create your own space agency and base with launch pads, research labs, astronaut training facilities, and much more
  • Construct custom vehicles from hundreds of combinations
  • Launch satellites and crewed spacecraft to explore the Solar System
  • Run mission control as you solve the various challenges of turn-based missions to earn scientific advancement and public support
  • Recreate famous missions conducted by NASA, ESA and CNSA - including the Perseverance Rover, Ingenuity Helicopter, Zhurong Rover and Rosetta space probe missions.
  • Explore an extensive tech tree and compete or collaborate with other agencies to plot your roadmap to Mars
  • Choose from five unique space agencies, each with its own traits, base, vehicles, and spacecraft
  • Build with unlimited freedom in a fully-customisable Sandbox Mode

Manage the Mission

Will you push to stay ahead of the other agencies, or focus on testing and research? There are multiple ways to ensure the first person on Mars is under your command. Every choice matters: will you invest in the most advanced technology or take risks in the rush to the red planet?
Using actual events and missions as inspiration, can you handle the challenges faced by real space agencies?

Journey to Mars

Management is a vital aspect of Mars Horizon. You'll need to design and build the right spacecraft, hire and train the crew, and make strategic decisions as mission control to survive the journey to Mars.
Enter into diplomatic partnerships with other agencies to share the rewards of space exploration, or risk going it alone to gain greater prestige. Construct the ideal rocket from historically-inspired vehicle parts. Hire contractors to construct vehicles and use their unique benefits to gain a key edge over your competitors.

Face the Challenges

Launching a payload into space is only the first step. In assuming the role of Flight Director of mission control, you'll need to manage your spacecraft's resources and solve strategic challenges in turn-based missions in order to succeed. But beware: space is a very unforgiving environment.
These are the critical moment-to-moment decisions of mission control; do you spend power to fix a malfunctioning antenna or save it in case of an oxygen leak? Perhaps risking that extra three months of mission planning could have avoided this issue?

Supported by ESA

Mars Horizon has been made with the input and support of the European Space Agency and the UK Space Agency.
We’ve collaborated with numerous experts in space exploration from the ESA in creating Mars Horizon. From engineers developing the technology used in Mars programmes, to those designing the next generation of missions, bringing an unprecedented level of authenticity, realism and legitimacy to the gameplay and scenarios.
Dig deeper into the game via our podcast, including discussions with staff from the European Space Agency and UK Space Agency.

You’ll grind your teeth when you’re the last man on the moon, but the more you persist, the more Mars Horizon pulls you in. If you’ve got even the slightest interest in the Space Race, this is one of the most engaging ways to experience it.

8 / 10
A fun management game about running a space program and shooting for the stars that sacrifices some of the visual wonder of space travel in order to remain accessible.
by Cosmin Vasile
7 / 10
In the end, Mars Horizon turns out to be quite a simple game, despite the initial complex impression. Because of the repetitive gameplay, although the game has replay value, most players will be rather bothered by the end they finish the race to Mars and will not be tempted to try again. It is worth a try if you are a fan of space exploration, but curb your enthusiasm regarding the fun the game can provide.
