This script simply lets you maintain a movement speed close to your normal running/walking speed when you are sneaking. You will, of course, still not be able to sprint.
Without modding tools, the only way to attach the script (which will keep it running in the background) is to use a console command. Therefore, please read the installation instructions carefully.
Installation
Extract the contents of the .zip to the directory where your Starfield.exe is located.
In the game, use the following command:
player.aps StealthRun
You only need to run this command once per playthrough (to include NG+). Multiple uses of this command will spawn multiple script instances and potentially cause lag!
Updating
To update to a new version, simply replace the old file with the new one. You will not need to re-run the command unless you have started a new game.
Uninstallation
Delete %Starfield%/Data/Scripts/StealthRun.pex
Recommended Mods
Baka Achievement Enabler to keep achievements enabled when you use console commands.
Starfield Script Extender (SFSE)
