The code to unlock the vault is 1940 which is the year that Catwoman first appeared in the comics. This will unlock new galleries as well as a new comic book cover.

If you have problems finding Cat Eyes, press Y to use your cat vision. Some of them are hidden behind posters and other objects.

When battling Laurel Hedare, Tom Lone, or the man in black who tries to kill her, always attack them from the back. You will be able to hit them about three times before they attack again. Otherwise, you will just roll away and get hurt.
