This is indeed a very good level and i liked it :-). The "log messages", the excavation site, the secret labs are all well story design decisions and i believe the map could have easily been part of a larger episode with a more detailed story behind it.

Also i liked the clean architecture (This is how i like the base maps :-) and the design contrast between the base and the underground area.

A cute level that features a techbase and a kind of mines area.
Author achieved a nice ambience for both areas

Detail is well done and general gameplay is fair.

Definately this is a map you will enjoy.

But on the bad side, the map does not gives you any surprise or something that will be remembered. Almost all of the monsters placement is something like predictable.
It's also possible you don't realize to take the Nailgun (because there are an alternative path), so you will be fighting with the Axe guessing if you miss something or not (because the DoubleShotgun ran out of ammo).

Neat and original visuals - especially digging the bricks working nicely the white idbase parts, and also the library. Some good exploration, several areas and items being entirely optional. Not very memorable in the long run though, and the attempts at the story fall short since there's no logical conclusion to it.

I would rate this 3.5-4.
It is obvious that Willem put a lot of love into this map. There is generally a strong theme, and the way that the unit is divided into little distinct areas is nice. The gameplay tends to be somewhat meh however, especially in the mines, and is often too easy - especially if one finds all the secrets (one of which is rather expansive and very rewarding when you find it). The final fight could have used a bit more - one final round or something to finish things off. It's strange - technically it is quite good. Clean build, lots of quasi-realistic touches and attempts to add atmosphere, interesting and obivously well thought out layout. But there is just something about it that keeps it from being excellent.
