I've gotten to the part where you:
[hint]Download kk2.zip, open it and find a txt file, get told to go to the main frame and go to securipedia[/hint]
but what do I do now?
Nice to see that game is still (occasionally) played...
Spoiler
I suggest you go there and poke around a little. Maybe you'll find something interesting?
Also, apologies in advance for the ending. :P
The only page I can find is
Spoiler
the one about outlaw labz
but that's all :(
Maybe you should
Spoiler
do a search for the name of the security system you want to bypass? Maybe it'll tell you something useful... or you can find an interesting new link on one of the pages it refers to...
Also, if you want some spoiler tags, it's [ hide] (minus the space, of course), not [hint] ;)
