Ok so iv figured out that
local HttpService = game:GetService("HttpService")
loadstring(HttpService:GetAsync("link"))()
`will insert a normal script but for some reason i cant seem to find out how to make it local?
perhaps putting into Backpack or something.

Btw this is inserted into the game via the :s code cmd in khols admin epix edition (with loadstring and http enabled)
It would not work in a Local Script anyway. Roblox disabled LoadStringEnabled for all local scripts to try and prevent exploits.
^, Use a alt website to run a http local loadstring. ( Like oxcool1's SB )
