does anyone know how to get into the little crypt in the courtyard... their IS a door, but its locked... i think it might have something to do with the one tombstone you can smash... its the ONLY one, so it might mean something?

Dude, its quite simple.
There is a series of buttons you can stand on on the floor with the correct code written right in front of them. Once you have completed the code stand on the blue thing that wont hurt you anymore and the door will open.

lol... not the main door to the rest of the temple... in the front yard, to the left of where u start... there's a little building with a door that wont open... u find some arrows behind it, i think...
