Launch smarter, not harder—Kerbal Space Program v1.12.4 (GOG): stable, moddable, and ready for liftoff. Join the challenge: can you land a reusable SSTO on Minmus?

The version sits at a perfect compatibility crossroads.

Transforms rocket engine plumes into beautiful, realistic exhaust effects.

A long-requested feature, the ability to rotate docking ports after docking allows for perfectly aligned space stations. No more crooked solar panels or lopsided bases! The Best Mods for v1.12.4

Version 1.12.4 is the ultimate target for mod compilation. The "Big Four" mods— MechJeb (autopilot and information), Kerbal Engineer Redux (data), KVASS (visuals), and Restock (part textures)—are all perfectly tuned for this version. The GOG release allows the user to curate these manually, often leading to a more stable "DLC-free" or "DLC-controlled" experience than the Steam Workshop, which can sometimes auto-subscribe you to conflicting dependencies.

Adds volumetric clouds, city lights on night-side Kerbin, and atmospheric dust storms to Duna.

If you have just purchased the GOG version (often listed as setup_kerbal_space_program_1.12.4_(64bit)_(54345).exe ), follow this quick start guide for the "best" experience.
