There is a near-full FAQ, written by the magnificent Bronzie (made using the I-guide's crib notes as source) available at GameFAQs, here.
However, what with there being buttloads of people who simply cannot be bothered to click a link, I have here a list of the more important things from the Krypt, lifted shamelessly from the FAQ (what follows is basically the most important stuff relating to gameplay, or the stuff everyone/most people would want right away). For all intents and purposes, this is a condensed version of Bronzie's FAQ.I'm not trying to rip him off - just trying to cut down on repeated topics here, and increase general awareness of the Krypt's Kontents. Among possible scenarios, I'm sure Bronzie does not want to be bombarded with E-mails, and no one likes seeing the same topic twenty times. That was the reason I have created this topic, to be blunt, to cut down on the psychotic amount of "I've found ___", or "where can I find ___" posts that will invariably pop up in the weeks following Deception's release.
For those who ask about where certain keys are found, or cannot find a specific key, I can only advise you to search harder, return at different points in time, and pray.
And a couple of points:
No, no one knows where the hell to find Liu Kang at this point.
No, no one knows anything yet about the superunlockables, if any.
However...
