Alicia is the name of a computer AI in Call of Duty: Black Ops. She is only seen on the computer in the main menu.

She acts like a psychologist and is an easter egg. To unlock her, go to the computer behind Mason's torture chair. Type alicia, and this will start a session with her.

By typing in anything into the database she will make any of the following responses:

Tell me more about yourself.

Do you feel that is the source of your problems?

I'd be interested in hearing more about that.

Can you tell me more?

Does that question interest you?

Can you go into greater detail?

This is very interesting.

I think you're on to something there!
