They’re rhythmic and enigmatic. I can’t remember if we listened to them in Russian to hear if they sounded suitably intimidating, we must have. Because they were really melodic; I’m not sure we would have gone with them [if they weren’t]. But we wanted ones when you read them on the screen you’d have some reaction to it. Like ‘Duress,’ and ‘Freight Car.’ It’s really just us coming up with stuff. There’s not a lot of rhyme or reason to it.
Por outro lado, como descrito na resposta de Rogue Jedi, alguns parecem não ser tão aleatórios. Os escritores dizem que algumas das palavras servem para provocar uma reação.
