Hey Starr, Xbox ehy? Damn yanks
But the secrets, well, seen both of em, the 1st one is on disc 1, at the end of the documentary, just as the dreamchaser thing is on I think, or right at the end anyway, there is a little bono macphisto head, press enter when that pops up. You'll be taken to a screen where you gotta type in "1" "9" "7" "6", then enter or on mine another screen popped up, and I selected "Bonocam1" and it played, thats elevation.
Number 2 is on disc 2, go to the "?" option the menu screen, type in "1" enter "9" enter "9" enter and "1" enter, 1991 following each number with enter basically, and it should come on, UTEOTW in bonocam.
Now the 2nd 1 works everytime for me, other 1, well worked no prob the FIRT time I trid, never has since
Well, good luck! they're cool!
