The mapping is very well done. I can see myself having fun on such a level, maybe in a deathmatch context.
However, the enemies and the gameplay of the map itself is a joke. I might even go so far as to say the level is impossible without cheating. From the first room it gives you a super shotgun and then expects you to kill roughly 30 Revenants while a Cyberdemon hangs around in the background just waiting for a stray bullet to hit him.
Ended up going with Godmode and enjoying the well put together map. Its very easy to get lost, however, and some hallways just seem to end with little value in them.
Overall a promising map, maybe just get somebody else to do the enemy placement.
