Does anyone know the "Kode" that you have to put in on one of the Krypt blocks? Its the only one that requires a code and i can't find it anywhere.

I'm not sure exactly what you are looking for as I have not played the game, but you can try finding this thing online, such as in a site with guides.

For example, here is the link to MK Arm guides on gamefaq: Mortal Kombat: Armageddon FAQs - Mortal Kombat: Armageddon Walkthroughs - Mortal Kombat: Armageddon Guides (http://www.gamefaqs.com/console/ps2/game/931479.html)

The codes (if that's what you need) are on the "Cheat Codes and Secrets" page.
