I'm generally not the type of person to be appreciative towards art. It's just not my thing. Sometimes though, I'll slow down a bit and notice how gorgeous most of, if not all of the multiplayer maps are. It's something that most of the time, you'll only notice when you decide to slow down. For instance, you'd never notice that the actual hotel on the map "Hotel" is actually really huge, while being engulfed in a storm, with a light-house just outside of the shore. Another example is Rustlung, very little people notice that the windows behind the Silverback spawn actually show that the map is on a ship, hauling through what looks like a hurricane.
I'm curious to see what other people have noticed about the map scenery, as well as learning anymore of these off the map scenes.
