Anyone know how to work a voice changer to make it sound like you're a Combine Soldier from Half-Life? 
There's a discord group but they keep their near 1:1 method under wraps and refuse to share it with anyone who they don't trust.

All I know is that "FL Studio" is involved in creating the voice effect.
