When I played this earlier, I noticed an upsetting lack of metal as an offensive engineer, and found defensive engineering nigh impossible, due to the lack of defensible spots on all but the last point, on which I had one comfy spot, because most of the others were vulnerable to the Rape Room where Monster Dispensers once did dwell.
Beyond that, I had several issues with the map, but none for which I could make suggestions that might lead to the map's betterment.
