This is a great map!!! It is based on three rings, the outer one with windows that open so you can pick off your friend, the inner one that has the most room with some aliens and weapons, and the inner one that I felt a little cramped at times. All in all a cool map with a couple of secret transporters to some secluded areas..and just enough media but not too much. Water in this case. This one can be played solo also just watch out for the inner ring. Construction is quite good and there are some cool lighting sets.
