Ghostbusters: Spirits Unleashed

Spirits Unleashed focuses on online multiplayer gameplay for up to five players, focusing on 4v1 matches with asymmetrical gameplay. Each player is able to create their own Ghostbuster avatar, with the Ghostbusters' headquarters acting as a hub between matches where players can change their avatar's appearance, clothing and voice, as well as manage items and upgrades they have unlocked. At times, players will also be required to visit certain areas of the hub to progress events in the game's storyline. Matches – dubbed as "jobs" – are initiated at the hub and can be set to a specific location or a random choice, with players able to designate whether they prefer to play as a ghostbuster, or be chosen to control a ghost in the match; players may also opt to let an AI bot control the ghost for the match.

In a match, the goal for each side is specific: the ghost's aim is to haunt the selected location and avoid being captured; while the ghostbusters must focus on trapping the ghost, with the option of closing rifts to reduce the ghost's chance of success, but must do so before the ghost can fully haunt a location. If a ghost manages to fully haunt a location, a countdown timer begins, and the Ghostbusters will be required to close down any active rifts and capture the ghost before it runs out, otherwise they lose the match. Each side functions differently during a match, with the ghost working on their own and using a combination of stealth and sabotage techniques against their opponents, while the Ghostbusters must use teamwork, co-ordination, and a variety of gadgets to defeat the ghost. Both sides earn experience for their equipment/abilities, while at the end of the match, players earn experience towards their overall level, which reaching certain thresholds will unlock new ghosts and appearances, and new items for use in matches and customising their avatar's appearance. Additional experience can also be earned by completing daily and weekly challenges focused on different tasks, such as destroying bins, or completing a set number of matches.

Following the events of Ghostbusters: Afterlife, Ghostbuster founders Raymond "Ray" Stantz and Winston Zeddemore re-establish the Ghostbusters, with the latter acquiring and reopening the organization's old headquarters in a New York firehouse. Believing a new generation is needed to tackle the paranormal and occult, the pair recruit two new members to serve as staff members at the headquarters – Catt, the new co-ordinator and assistant; and Eddy, a technological genius assigned to lab work and research. The group soon begin recruiting a new selection of rookies to serve as Ghostbusters, shortly before Ray takes delivery of an occult relic known as the Spirit Guide, written by John Horace Tobin – a researcher of the occult, with whom Ray is fascinated.

After conducting a few jobs, the new Ghostbusters are tasked with checking in on a package from Ray and Winston's close friend Peter Venkman, which turns out to be an old ghost trap that no one at the firehouse can account for. Tasked with using it on the ghost containment unit, the trap suddenly malfunctions before a mysterious force known as "The Nameless" escapes and possesses Winston. Concerned for his friend, Ray and the others order the Nameless to exit his body, only to find something has tethered it to Winston. Eddy soon works to find a way to separate the pair, but his efforts backfire and cause the Nameless to open a rift into the realm of ghosts. With further research into the matter, Eddy advises the Ghostbusters to enter the rift and determine if they can find something beyond it that can free Winston.
