Even the Cyberdemons were cake when I had a ton of ammo and the rocket launcher and the plasma gun to beat them with. That, coupled with a wide open area where avoiding their rockets was way too easy, they were defeated in short order.
So, if you are a moderately good player, you might be amused by this map but you won't find it particularly challenging... Lesser players may find this a challenge but the overabundance of weapons/ammo might prove me wrong.
I'm a little torn on how to review aspects of this map so I'll save the hard stuff for last and start with the gameplay. There was an overabundance of pretty much everything in this map - too much ammo, too many weapons, too much health - you name it. There were a couple of times where the author caught me out but for the most part, the beginning was the most difficult and once I got my ass handed to me a couple of times and I had an opportunity to see where the fire was coming from, I was all set. It was cake after that. There were a couple of good traps, as I said, but for the most part there was nothing particularly strenuous about the battles I found myself embroiled in. With the plethora of creatures in this map and the difficulty that each should have provided, the gameplay was rather bland. There were Revenants and Arch-viles and at the end not one, but two Cyberdemons and pretty much every other creature in the game besides and it STILL wasn't that difficult on UV. I'd say it was my expert skills but I don't believe so. There were a couple of dynamics at work here....
