As of the current patch (1.6.2), there is no public "nuke" exploit. However, dataminers have found unused variables in the game code: experimental_thrust_modifier and ignore_staging_validation . Some believe these are developer tools left for debugging. Others believe they are the seeds of the next great blueprint revolution.
If you are a new player searching for the nuke blueprint, stop looking. It’s gone. Instead, take this as a challenge. Launch a Saturn V. Do a Titan aerobrake. Land on Mercury with chemical rockets only. Master the real physics, and you will realize you never needed the nuke in the first place. sfs nuke blueprint patched
The realists argued that the nuke blueprint broke the core educational value of the game. SFS is meant to teach real orbital mechanics—delta-v, staging, Hohmann transfers. A single-stage-to-anywhere nuke rocket bypasses the entire tech tree and makes Mars landings boring. As of the current patch (1
