In the walkthrough I watched the Securitron said something about it being vital to clean up corpses from the streets due to health hazards. Can't imagine there were many bodies left lying the in the streets of Vegas before the bombs fell. I dunno. :shrug: My main point is IMO the VA is cack for the Securitrons. lol
Why does it bother you so much? I don't really care how a robot talks, they all talk
weird/bad because they're not human. (well in fallout 3 there were more bad actors for human characters than there were for robot characters)
