de_newyork_aquaduct_v2 is a mod of the hardware test map. The map is completely subterranean. The map has special lighting and sound effects. The CT side has full control of the bomb site A but the T's have a major advantage on a upper tunnel to balance the map. The map is mostly close combat but 2 areas does have room for snipers.
