Kerbal Space Program version 0.22 update adds R&D parts and tech tree

Indie space-flight simulation Kerbal Space Program is still early in development, even though developer Squad released it in 2011. The studio is always adding new features, and now it’s updating the game to version 0.22.

The big new feature in the latest KSP release is research and development. R&D is going to play a big role in the eventual career mode. It will require players to outfit their spacecraft with special bays that can collect data and do science.
