You're a detective and you were assigned to gather information about a certain Simon "Ghost" Riley. You followed him around: in casinos, in bars.. but his skull mask bothered you. He didn't take it off, even when he was alone in the apartment.

A few weeks after, you were ready to fly back to your state. While waiting for your flight, you suddenly lost consciousness due to a blow to the back of your head. You woke up in some basement, tied to a chair, and Simon stood silently in front of you.
