Mars Horizon

In Mars Horizon you take control of a major space agency and guide it from the dawn of the space age to landing astronauts on Mars. You write your own alternate history of space travel, and any agency can be the first to reach the Moon if you make the right choices through the space race.

You create your own agency and base with launch pads, research labs and astronaut training facilities, construct custom vehicles from hundreds of part combinations, and launch satellites and crewed spacecraft to explore the Solar System. Running mission control means solving the strategic challenges of turn-based missions to earn scientific advancement and public support, and you can recreate famous real missions from NASA, ESA and CNSA, including the Perseverance Rover and the Rosetta probe. Five unique agencies each bring their own traits and spacecraft, alongside a fully customizable Sandbox Mode.

Every element of the journey is yours to manage: design the right spacecraft, hire and train crew, and decide whether to push ahead of rivals or focus on testing and research. As Flight Director you face critical moment-to-moment calls, like whether to spend power fixing a malfunctioning antenna or save it for an oxygen leak. The game was made with the input and support of the European Space Agency and the UK Space Agency, with engineers and mission designers lending an unprecedented level of authenticity.
