Changed ANY scripts whatsoever that relate to power?

What issue are you having? The minigun is already made in APE so you just have to edit it there.

Works great, Can you put that when you die the weapon be the start weapon?

Did you give them to yourself through console? if so, that's the reason they don't work.

You won't be able to do anything special inside radiant. The way all triggers work is they are included inside scripts.

Here is an example:

function init() // Initialization variable, call this in your mapname.gsc to start the script.
{
	// Do whatever you would need to do here, not required for this.
	thread GetTrigger(); // Calls the function while threading it so multiple functions can be executed at the same time.
}

function GetTrigger() // Function where all code for what you are currently doing is called.
{
	trigger = GetEnt("triggertargetname", "targetname") // Replace "triggertargetname" with whatever you put in the targetname kvp in radiant.

	// You would want a while loop here if you want the trigger to be able to be activated more than once.

	trigger waittill("trigger", player); // Waits for the trigger to be activated, player isn't needed but is useful.
	ModVar("timescale", 0.5); // Sets the timescale to 0.5
}
