A space exploration game at its best, High Frontier 4 All! The popular boardgame is now going digital.
Embark on an epic journey through the stars with High Frontier 4 All! As the head of a cutting-edge spacefaring company in 2020, your mission is to profit from the exploration and industrialization of our solar system. Each turn, make crucial decisions that will shape your strategy—perform key actions, move your rocket, and advance your company’s technological prowess.
High Frontier 4 All invites you to lead Earth's spacefaring factions in the ultimate race to industrialize the solar system. Bid for cutting-edge space technology patents and launch your rockets into Low Earth Orbit (LEO), where water serves as both currency and fuel. Strategically build and fuel your rockets to explore planets, asteroids, and more. Claim, prospect, and transform distant worlds into industrial hubs by establishing factories that produce vital resources.
Compete against other players over 48 turns (spanning 48 years) to earn victory points by making off-world claims, building factories, and achieving exploration milestones. The more you industrialize, the higher your stock prices soar, pushing you closer to victory!
With each turn representing a year, the game unfolds through Sunspot Cycles, offering diverse strategies and gameplay with multiple modules. Follow a structured, immersive ruleset that ensures no two games are the same. Whether you’re racing for glory or constructing a thriving space empire, High Frontier 4 All offers deep strategy, endless replayability, and the ultimate space exploration experience.
