By Floyd. This is my first level for D3. The ideas for the tower room and the digging room are from Pazuzu aka Metatron, the rest are designed by me.
This level was built with the old fashioned dark D1 and D2 athmosphere in mind. If the coronas bug you, just disable them in the Descent 3 detail options. You should get used to the layout quickly and it should play well with 4-6 players, although it could hold 8 people certainly.
