I would really like to find that cryptic addon pack though, it was a bundle thing, just like the unreal special edition etc...I talked to Eric Reuter and Nigel Kent about it but both didn't have it anymore, maybe if I asked few more years back....
I made a thrad in Epic games forums in case anyone will notice it:

I sent emails to various Epic members about it too, but nobody except Cliff Bleszinski replied on it and it was more of a beta issue. He was actually happy about the idea of getting the beta or unreleased content released in some form, which wouldn't be giving away whole beta, so it would either include a check for people who have unreal installed or something like that....but after he talked about it with more people he said that they said something like that the company needs to protect itself and that all he could do is to tell them to not make any legal actions against it.
Obviously the lawyers can be a little pain there...
But that was a while ago since he told me about it and also he had no idea where he would get the betas or any of that content.
