Where can one acquire it? or can it not be acquired?

I had it working awhile ago however I do not remember the steps to get it working. The files can be found there. As you can see nothing new since 2007 sadly.

[edit]

Nothing new for the mod itself as of 2007*

This is their other site: http://www.pdark-mod.com/joomla/

Unfortunate how this has been dead for a while; it would've made a great multiplayer game. At least it still exists in the form of maps for GoldenEye Source.

Since they kept the website and Steam group up, maybe they'll make something of this eventually. Under the circumstances I'd say it's possible this is still being developed. After all, the active GoldenEye: Source mod took two years just for a minor update.
