In the planning phase, the player first allocates the funds they have to various budget items, like crew selection, station modules, and research and development.

Then they choose their crew, who have intrinsic task sets (like piloting and physics), and varying levels of competence and compatibility with other potential employees.

In the final stage of the planning phase the player can create a simulated station with an unlimited number of parts, and without dealing with the later constrictions of the EVA.

Once the shuttle is in orbit, the player is tasked with assembling the components they brought up (or firing off any satellites they have contracts for) in the Extra-Vehicular Activity or EVA phase.

Here the player directly controls an Orbital Construction Pod, a small ship with mechanical arms that an astronaut can use to move large equipment.

Info rated Project Space Station five stars out of five, describing it as "probably one of the most ambitious programs ever developed for the Commodore 64 ... a fun, complex simulation".
