Kerbal Space Program makes history today with the launch of its first expansion! Kerbal Space Program: Making History Expansion adds a wealth of new and exciting content to the game, including a robust Mission Builder that lets players create and share their own scenarios, and a History Pack containing missions inspired by historical moments in space exploration. The Mission Builder is a new feature that puts the process of creating and editing missions in your hands with endless possibilities. You’ll be able to customize your own missions to include launches, landings, rescues, malfunctions, explosions, repairs, and much more. You can set unique victory conditions, add exciting challenges, and place unexpected obstacles to keep other players on their toes as they play through these complex missions. Challenge others to complete your missions by sharing them with the Kerbal Space Program community! The History Pack includes a variety of pre-made missions inspired by humankind’s own space exploration. Now you can spacewalk, pull off a crash landing, and attempt to recreate some of the most memorable moments inspired by historic events. All with our unique Kerbal twist, of course. The expansion also includes a more than 70 new parts and astronaut suits inspired by the Space Race that you can use throughout Kerbal Space Program! Additionally, we’ve kept our promise that all players who purchased the game through April 2013 will receive the expansion for free. To redeem the game click here and follow the instructions. Kerbal Space Program: Making History Expansion is now available on Steam and will soon be available on GOG and other third party resellers.
