X-Men: Next Dimension Cheats

Beat 10 characters in time attack mode using any
character in under 15 minutes

There are three possible endings in the game in story mode:
Regular ending (Magneto's Victory): Defeat Bastion with Magneto.
Alternate ending (Phoenix's Victory): Lose the Magneto vs. Bastion fight and you will go to the Phoenix vs. Bastion fight. Defeat Bastion with Phoenix.
Secret Ending (Fury of Dark Phoenix): Get a "Perfect" victory in the Phoenix vs. Bastion fight. This will also unlock Dark Phoenix as a playable character.

How on earth do you save the game on story mode because the only way I know is to quit the game.
Go to options and select save game but that means I've lost my data by quiting and saving.
PLEASE HELP ME
