The Engineer's Blueprints: Viaduct

Overview of the King Of The Hill map Viaduct (koth_viaduct) from the perspective of the Engineer. This snowy map is perfect for the holiday season, so queue up and build some Sentries in the Snow! Feel free to use this video walk-through as a guide to the basic strategies and common building placements you should use while playing Engie.
I considered going over Product, but there are so many big differences between the two that I'd consider Product a completely different map. Not to mention, Viaduct is an official Valve map and Product is not.
Maybe in the future, the devs will edit Viaduct to reflect the balance changes featured in the pro version, but I would be very surprised if they added Product to the game when Viaduct already exists.
