Thank you very much, I have finished the last part of the map, this is the underground part. As I said before, the celestial is water, there is no where the zombies come out, because for the zombies to come out they must follow you down there, there is a small button that will open some floodgates that will make a small wave of water come out that will drag the zombies, but it can only be used once every 2 rounds, in addition to that so that the wave does not drag you, you must stand behind the walls. by the way, do you think you make the place dirty? to make it like a sewer.
