Kerbal Space Program: Making History Expansion will feature two major new additions to the game in the form of the Mission Builder and the History Pack. The Mission Builder will allow players to make custom missions that are then shareable with other players. the History Pack is a collection of pre-built missions made by the developers where players can play out famous real world space missions.
Simple interface: Using an intuitive drag and drop node interface, you can easily create new and exciting new missions for yourself or others to enjoy. Creators can also add constraints such as time, fuel and parts limits; as well as unexpected mission events.
Recreating history: Included in Kerbal Space Program: Making History Expansion is the History Pack. Players will be able to experience the trials and tribulations of the early days of Space Exploration on missions inspired by real life historical events.
New parts: Aside from mission creations tools, Kerbal Space Program: Making History Expansion will have additional parts such as new fuel tanks, adapters, decouplers, fairings and command pods… inspired by both American and Soviet space programs!
Kerbal Personal Parachute: Your astronauts will now be safer in case of imminent disasters with all new personal parachutes. So next time Jeb is in trouble and all systems are failing, you can simply eject him and activate his parachute. Then, you just have to hope, there’s an atmosphere to slow him down…
Challenge other players: A new addition to Kerbal Space Program: Making History Expansion will be the concept of scoring. At the end of a mission you will get a numerical score to compare with your friends and the community.
Developer Squad is keeping the information on the expansion's price and release date to themselves. Nevertheless, staying true to a promise the developers made almost four years ago, the expansion will be completely free to players that bought Kerbal Space Program before April 2013, coming as a nice gesture to those who supported the game in its early development.
