TF2-Beating MvM Wave 666 as Sniper

-This is a little series I'm making were I beat wave 666 as all the tf2 classes.
-I've beaten this wave so many times and gotten so close to getting A+ (so far record being 8) that I decided to record me beating it as proof since a lot of people think It's impossible. So why not do it with every class :)
-Also I just don't see a lot of this map on CZcams, so...here ya go.
-The actual map is called mvm_ghost_town
