It sounds like it’s being ran through one of those anonymous voice filters while the person saying the lines is trying to fake a deep voice.

It doesn’t fit the character model whatsoever. I truly hate it. Do we even know who’s doing the voice yet? Maybe rockstar is filtering it so we can’t identify it yet I don’t know. If it’s filtered great that’s not what we will be hearing. If it’s not. Then it’s a major problem
