OK, I might have to load up the game to try this. Seems that if you shoot 3 hidden cowboy hats in Chapter 3 Act 1 of
Gears of War 2 on insane difficulty, everyone starts to wear cowboy hats. You can see in the video where they are and how it looks. Easter eggs are always fun and I think I might to do this one to see for myself on my TV. Thanks
