The link to the megapack in the first post is dead (as is the entire RusFolder file-sharing service). Someone should replace it...
There is a new project on moddb related to NCF, you can see it here.
It is maintained by Psatka and me. Currently you can find the NCF core pak in the download section.
I have the Mega pak and will upload it shortly.

Here it is, I think. It allows you to spawn creatures from NCF on generated maps.
As far as I know, the original random map generator cannot do this.
The only way you can do it is by using an MMH55 tool called "Map mixer" by Ciphy. You can read more about it here.
