Jack in the Dark is a small game made during Alone in the Dark 2 production. It was used as a promotional game distributed at Christmas 1993 (just before Alone in the Dark 2 release). The game was on a single floppy in a golden wrapping featuring a Jack-in-the-box illustration on the top. It is a short adventure featuring the young child Grace Saunders. During halloween, she enters a small toy store after dark and gets locked in it. There, the toys are alive, and Grace must save Santa Claus from an evil Jack-in-the-box. Jack in the Dark is an adventure game that focuses purely on puzzles and has no combat. Later CD versions of both Alone in the Dark and Alone in the Dark 2 came packaged with Jack in the Dark.
