Outdated Mod

This mod is not known to work with the latest version of Kerbal Space Program. Proceed with caution.

G-Effects: blackouts, redouts, G-LOCs

The work was originally started by russnash37 who gave a permission to take over and extend his project

I've tried to make focus on realism as much as I was able to research the subject so the default settings assume that all kerbals including tourists are trained astronauts wearing G-suits. Pilots are more trained than others, of course.

The following G-effects are simulated:

  • Blackouts/redouts
  • Loss of color vision a.k.a greyout
  • Tunnel vision as G rises
  • Kerbals grunt while they perform AGSM (anti-G straining maneuver) and take a heavy breath after
  • Blood beating in kerbal's ears on redout (wear headphones with good bass and you'll feel it)
  • G-LOC (G-induced loss of consciousness)
  • Kerbal deaths of a sustained over-G

G forces have different severity in four directions: upward, downward, backward, forward, so you may find that a kerbal launched in a rocket stands more G than a kerbal piloting a plane upside down on a circular trajectory. Kerbal's specialization also affects how much he can stand.

You can use this mod together with KeepFit by timmers_uk. In this case kerbal fitness will affect their ability to withstand over G effects (supported by G-Effects v0.2.3+ and KeepFit v0.8.3.3+).


Place contents of the GameData folder of the zip into your KSP/GameData folder

Configuration: Configuration of the mod is done via G-Effects.cfg file. Look through it to have an exhaustive description of its parameters.

The sounds are still a little WIP so you always have an option to disable them via config file if you find'em too annoying.
