I was fairly disappointed to see all the bots were BLU painted. So I made this quick "fix" Their eyes are still blue, and they still uber blu
There are two screenshots of giants to show it works on them too, I didn't get to see the pyro or demoman so I couldn't get screenshots of them, but they should work fine.
Extract to the Team Fortress folder to use
EDIT: Moved to Robot section, since there apparently is one now.
