Well the first two things you mentioned are already posted. But the press start screen and do nothing does the following. It shows character profile, character kata's( only Kitana, Quan Chi, Frost and Blaze) and the Scorpion video were he is throwing fire balls at the acid Buta's. Its a good guest though( I suck at finding secrets)

The time that says on kenshi's eyes has nothing to do with the 'final ''secret'''.

I've heard that concept of being the secret before. But nice guess as stated before.

It has already been stated by the development team that the time on one of the glass eyes is just the time that the picture was rendered. It has nothing to do with the final secret whatsoever.

So... what exactly does the so-called 'whisper' in the 'K'rypt have to do with your theory? What did you do, just pointed it out or something?

I only heard of this 'Whisper' in the Krypt. I never actually heard it, so it muight be fake.
