I forgot where I downloaded it, so, eh, sorry, but know that it is possible to get it off the internet. Small file size, too.
And as for the quality of the game, it's not particularly good like Atlantis was, and it assumes that you've seen IJatLC in some places. Probably because they got lost in their plot. I also had to do some things that I would've NEVER thought of doing in most areas without a walkthrough. i.e. Searching the library for Mein Kamf, a biplane instruction thingy, and a map of the catacombs that wasn't useful at all. All in all, I give it a score of 6.5/10. Atlantis is a MUCH better game, and if you can download that off the internet, I'd like to know where.
