With a very nice implementation of the industrialist theme, you almost expect to guys in hardhats climbing around in the girders that grace the upper portions of the map. The one main atrium tends to get a lot of the action, but don't expect much of a breather in the smaller side rooms. While the main atrium is good for some rail sniping from the top deck, it really seems to me that the rocketlauncher (located off the main path) reigns in Addiction.
