The 0.21 update to Kerbal Space Program has arrived, bringing with it a slew of new parts for building rockets and planes.
Also added in this update are a terrain overhaul, a revamped Kerbal Space Center, and the ability to “hire” specific Kerbals and assign them to missions. While this hiring feature currently doesn’t offer much beyond more control over who’s on what mission, it lays some of the groundwork for KSP developer, Squad, to begin working on the eagerly awaited “Career Mode” for the game – which is planned to add mission contracts and funding rewards for players based on their progress, providing a more Kerbal Space “Tycoon” gameplay experience.
