This is a really good map, a clear step up from the old map (which was still really good) though some of the combat encounters are still quite wild and there can be some ammo woes, with now some additional really quite tricky jumps to execute. It has some adventure / imsim / Tomb Raider-Half-Lifey elements for some of the secrets and a bit even for the progression, think "Telefragged" but on a different scale and more focused, even though this map also took me literal hours on nightmare as well. It was satisfying to find 14/23 secrets, maybe if I didn't try to beat the map in one sitting I would have found even more.
