I made this map to take place between, ImperialDestroyer and Destroyed Destroyer.
The top portion of the ship has 2 additional ways up so that it can't be so easily defended, this was actually an upgrade after the first time I published this.  There are many more rooms inside this map than any other destroyer map.  There are 3 additional ways to get to the outside of the ship (largest but lowest outside portion) by means of a ladder that comes from inside to a turret chamber on top.  The action is best with full groups as are most of my maps.
