Apology

[Terran]

Actually, this reminded me of when I hacked on a Nexon game called Combat Arms a LONG time ago. I had to use an injector too. Basically, you opened the injector and primed a "hack", usually a custom file someone made, and after the Nexon HackShield and stuff finish loading you quickly click "Inject" and the hacks "Load", then you can use them. Screw up the timing and you can get caught, but you also have to do it every time before.

I don't know if you'd have to do it when you launch Garry's Mod or if you do it when you join a server; probably the former.
