What is KSP2 Redux?

KSP2 Redux is a fan project built on top of Kerbal Space Program 2. The current work is mostly focused on:

• Performance work: Rendering, simulation, and memory improvements
• Bug fixing: Flight issues, UI problems, mission logic, map view behavior, and other stock problems
• Roadmap systems: Heat, vessel ISRU, colony-related groundwork, and later planned features
• Modding support: A better workflow for Redux-native mod development

Redux is a volunteer project. Work moves when people have time to finish something useful.

Current status

Redux is currently in Stage 0: Foundation. That means the public work is still centered on making the base game less fragile and easier to build on.

Current Foundation work includes:

• Performance optimizations and stability work
• Bug fixing across flight, UI, missions, and map view
• Debug tools for players and modders
• Modding SDK improvements
• Vessel ISRU, heat, and tech tree work that later stages depend on

Important Notes

• Beta Software: Redux is currently in beta. Some features may be incomplete or buggy.
• No Official Affiliation: Redux has no connection to the former KSP2 developers or Private Division.
• Volunteer Project: Redux is developed entirely by volunteers in their free time.
• Separate Installation: Redux installs separately from vanilla KSP2 - your original game remains untouched.
