High Frontier 4 All

High Frontier 4 All is a strategy game about leading a spacefaring company in 2020 and profiting from the exploration and industrialization of the solar system. You make decisions each turn, take actions, move your rocket and advance your company’s technology while competing with other players.

Explore and industrialize

Bid for patents on space technology, then build and fuel rockets to reach Low Earth Orbit (LEO), where water serves as both currency and fuel. Explore planets, asteroids and other destinations; make claims, prospect sites and establish factories that produce vital resources. The game has no limit on how many outposts, claims, colonies, factories or rockets a player can have.

A 48-year race

The game lasts 48 turns, with each turn representing a year. Earn victory points through off-world claims, factories and exploration milestones. Industrializing raises your stock prices and brings you closer to victory. Sunspot Cycles and multiple modules create different strategic possibilities across games, within a structured ruleset.

Rules and differences

Fuel calculations use the scientific rocket equation rather than the board game's abstracted method. Astrobiology, atmospheric and submarine site features have limited implementation. First Player Privilege is unavailable, and a Solar Oberth Flyby is treated as a regular hazard. Lander hazards function like regular landers.

Pathfinding may not always produce perfect routes. Heavy radiator components cannot be rotated to their light side; components that would otherwise rotate automatically are decommissioned.
