So is there a /give command for perks and powerups?
Would like to know as i haven't seen anyone posting this

So i saw NoahJ456 using cheats on revelations and he had mod loaded called "consoleonly"
Where can i find this mod?

I think that i didn't set it the right way.
As when i rename "gsc_sublime.zip" to "GSC.sublime-package" it doesn't change the file type it stays as .zip file and sublime can't read it as a package file
And it doesn't show up on sublime

I had the same problem but then I found that zombie spawner aka script_struct you have to set right KVP values.
