The only strange thing that happens after everything else is that it shows an image of the entirety of the u.s, except it's colored in red. Other than that I don't think there's anything else noteworthy afterwards. It could be a clue, but imo I feel it's more a red herring to throw you off. I'd be more than willing to go back and see if i did miss anything, but I'm certain I got most of what I could. Maybe using winrar and digging into the files could reveal something else? I rly haven't gone back into the arg for about a year now.
