Mountainside

Some improvements since 'Scarred Earth', but it still lacks a lot. Ligthing is fine, but the ancient parts are way too dark, especially that (way too long) corridor.

Connectivity is not very special, the vents are long and slow to move around. The doors have to be opened again and again, it takes a lot of speed out of the map. After all, I didn't found it fun to open doors again and again. Heh, that little door that contained the Long Jump Module even closed after me so I was locked! Man, get rid of those doors and vents. Some can be nice but here it makes the map annoyingly slow.

Crack the code? Nope. And I'm not going to invest time in it. Again, give us a clue where or how we can reach a secret. Cracking a code without any way to find it on a paper somewhere is madness. It's too hard and very annoying.

I've seen some details now and then and I liked them. I wish the rest of the map was some more detailed, it looks like just a lot of rough brushes. It lacks finesse. The research part also lacked sense of place. It could've been any sort of well, bunker-alike structure.

This map was made before Scarred_Earth.

Just a little improvement based on what Captian P said, you should make some paper in the level with the code on it, make it like a paper on a bulletin board or (a good idea) give hallways #'s and make all those #'s a code... wow I ammuse myself.
