OK, so I replayed Leptis Magna from the start on nightmare and this time I had no issues with ammo, which is a bit weird as I basically played it the same way. So it seems rather well balanced when it comes to ammo and I must have messed it up somehow the previous play.

It's such a wonderful map. I love how it comes up with surprises almost throughout the entire level and the secrets are just amazing as well.

@the silent, I'd love to see a 100% demo of the map.

Ah, thanks! I thought I had searched on YouTube, but apparently not. 

The video was of course very helpful and it was nice to finally find all three tomes so I could access the keys. I really like how dynamic the map is, with sections opening up, previously walled alcoves being accessible etc.

But I still have one secret left and hope someone can help me with that. In the very last room there is an alcove you can jump into and shoot a red star on the wall, but there's still one red star remaining and I can't locate it. Annoying to have a single secret left... 

The setup is symmetric with respect to the center of the room :) 

WTF, I had already looked there. Guess it would be easier if I upped the brightness a bit when looking for secrets. Anyway, thanks, now I can rest in peace. 

Perhaps reported earlier, but I have a glitch with the runes. After finishing the four maps with the runes, there are only two showing up in the antechamber with the portal to ad_end, so I can't proceed.

Guess I can use the console to add them, but I just wanted to report it.

BTW, Foggy Bogbottom was even more epic than usual with the help of watching a 100% play through, as I had missed lots of secrets and the entire roof top section previously. 

So I started over and redid the four maps with runes and this time it worked fine. 

Isn't there a longstanding bug with runes and savegames? Does someone remember? Maybe it was that.
