Mars Horizon (v1.4.2.1)

Mars Horizon puts you in charge of a leading space agency, guiding it from the early days of the space race all the way to the historic goal of landing astronauts on Mars. Set against a backdrop of real-world space exploration, the game invites you to shape an alternate history by making strategic decisions that influence your agency’s success. You’ll build and customize your space center with launch pads, research labs, and astronaut training facilities, while designing spacecraft from hundreds of parts to tackle a variety of missions. Managing every aspect of your programs—from hiring and training crews to overseeing mission control—requires careful planning and quick thinking during challenging turn-based events that simulate the unpredictable nature of space travel. Throughout your journey, you can choose from five distinct agencies, each with unique traits and technology trees, allowing for diverse playstyles and strategies. The game features authentic missions inspired by landmark achievements from NASA, ESA, CNSA, and others, including the Perseverance rover and Rosetta probe. Collaboration and competition with other agencies add depth to your path toward Mars, whether you forge diplomatic partnerships or race ahead solo. Developed with support from the European Space Agency and the UK Space Agency, Mars Horizon combines realism and accessibility, delivering an engaging blend of management, research, and mission execution that challenges you to lead humanity’s next giant leap into the cosmos.
