While the base game is in a great state after the final 1.12 update, the Kerbal Space Program mod scene represents some of the most creative community creations around, and help make everything that much better. It’s is a game about going to space, you might even call it a space game, where you plan, design, and fly the bold explorers of Planet Kerbin up towards the final (and only) frontier. KSP mods are essential for enjoying Kerbal Space Program.
