Rave in the Redwoods
- "The Soul Key is your one-way ticket out of Spaceland. But know this, this was only the first stop on Willard Wyler's film festival of horrors."
- — David Hasselhoff
The Soul Key is an object featured in the Call of Duty: Infinite Warfare zombies map Zombies in Spaceland, Rave in the Redwoods and Shaolin Shuffle. It is the player's objective throughout each map to obtain the scattered pieces of the Soul Key within each map.
The Soul Key acts as the key in opening the Soul Jar, an ancient jar which contains the souls of those trapped within Willard Wyler's movies.
At some point before the events of Zombies in Spaceland, the Soul Key was broken into several pieces and scattered throughout several of Wyler's movies in order to ensure the souls trapped within the Soul Jar would never be freed.
When A.J., Andre, Poindexter and Sally are sucked into Wyler's Zombies in Spaceland movie, they manage to destroy a UFO found in the movie, which dropped one of the pieces of the Soul Key. After picking it up, they are teleported to another one of Wyler's films, Rave in the Redwoods.
Inside Rave in the Redwoods, the four actors manage to find Kevin Smith, who had lost some of his memories of his time in the film. After the four help him recover his memories, he is turned into a Giant Slasher during a boat ride to Turtle Island after he realizes he supposedly killed his friend Jason Mewes. The four are then forced to kill the Giant Slasher, who drops another piece of the Soul Key. After picking up, they are again teleported to another one of Wyler's films.
In Shaolin Shuffle, a business man known as Arthur McIntosh becomes a convict and is forced to live in the sewers beneath the city of New York. After drinking a strange green goo, he becomes surrounded by rats, turning into the Rat King. At some point, the Rat King obtains a piece of the Soul Key. Eventually, the four actors, along with Pam Grier, manage to confront the Rat King in his lair in the sewers and defeat him, with Pam giving the final blow via stabbing him in the chest with her katana. With the Rat King's death, the Soul Key appears where his body was, with Sally picking it up as the four actors are teleported away to another film.
