Squad has added a “career mode” to Kerbal Space Program. The 0.22 update features a Research & Development Facility that tasks players with research missions. Experiments can be conducted which unlocks more advanced spacecraft components on a tech tree. Build rockets, fling them into orbit, and make your little green guys gather data. For science! Your kerbonauts finally have a purpose when they land on the Mun. If you don’t care for the career restrictions, sandbox mode is still available from the start of the game.
