This map really barely adds anything in the realm of actual gameplay areas. The only "new" area, the underground passage, is useless as it is safer and faster to just stay on the surface. This is mainly due to the only enterance being in the center arena completely defeating the point of a hidden passage as you cannot enter it without exposing yourself to enemy fire. The overhead vent is so hidden and risky that it is doubtable that anyone will use it. The biggest misstep is putting small, manually opening doors which should never be used in any legitimate map. Overall, it is turbine with a few useless areas sprinkled about for heavies to have their picnics in. I have not tested it, but I doubt it will play any different from normal turbine. If anything, worse due to all of the useless areas that work great for offensive nests due to the small entry points.
