Unlocking the 3 different endings:
The endings on the xbox verson are different then the 360 verson. The endings on the xbox verson are determined on what you do at the end of JBA HQ part 2.

Both endings have Enrica dying and Sam on the run from NSA. The only difference between the two endings is a quick 30 second news clip.

Good Ending - If you managed to defuse both bombs at the JBA HQ
Normal Ending - If you managed to defuse only one bomb at the JBA HQ
Bad Ending - If you chose to deactivate defusion of the bombs at JBA HQ

Elite Mode:
Beat solo mode at any difficulty
