Synopsis

A spaceflight sandbox in which you design rockets, planes and space stations part by part and fly them with a crew of small green Kerbals. Flights follow orbital physics closely, so reaching orbit, landing on a moon or docking two ships takes real planning. Career and Science modes add funding, contracts and research, while Sandbox opens every part from the start.

What people say

Critics praised it as a rare game that makes real orbital mechanics understandable and fun, with endless room for creative designs and dramatic failures. Players still love the satisfaction of a first orbit or Mun landing and note that it runs on modest hardware. The steep learning curve, thin tutorials, clunky interface and slowdowns with very large craft are the common complaints. Development has ended, so remaining bugs will not be fixed, and the troubled sequel has hurt trust in the series.

2.5 / 5

✗Controls feel awkward on a modern controller or mouse and keyboard
Flight relies on many keyboard shortcuts, and controller support is partial, with Steam Deck players calling it inadequate. Source: pcgamingwiki.com, vaporlens.app.
✗Menus, text or interface are hard to read on today's screens
Players widely describe the menus and in-flight tools as clunky and overwhelming, especially for beginners. Source: vaporlens.app.
✓Saving is fair: free saves or frequent checkpoints, little lost progress
F5 quicksaves at any point in flight, holding F9 loads it, and Alt+F5 writes a named save; Revert Flight undoes a failed launch. Source: forum.kerbalspaceprogram.com.
✗Hard to make progress without a guide
The built-in tutorials are widely seen as insufficient, and many players learn from wikis and video guides instead. Source: vaporlens.app.
✗Pacing drags: grind, filler or forced backtracking
Repeated failed missions, fuel shortfalls and lost crew make early career progress slow and punishing for new players. Source: vaporlens.app.
✓Camera and movement never fight the player
The flight camera orbits the craft with the mouse and scroll wheel and switches between chase, free and locked modes, and players raise no common complaints about it. Source: wiki.kerbalspaceprogram.com, vaporlens.app.
