I'd like to say that I'm glad to be a part of the mk5.org kommunity (frequent visitor, signed up only recently), and I'm a huge fan of MK. I've been trying to find out information concerning the entire storyline of the series, and I came to this link;

http://db.gamefaqs.com/coinop/arcade/file/mortal_kombat_plot.txt

It states the entire plotline of MK. However, it mentions that "according to the MKM manual, the two Sub-Zeros are the sons of a Lin Kuei ninja and an American woman. They were removed from their mother and forced to fight for the Lin Kuei. Also, they had a sister but nothing has been said about her since. "

I own MKM for the N64 and it doesn't say this information in the manual. Is this written in the PS version of the game?
