A demon has been resurrected in New York City which also causes a surge of ghosts to be drawn to New York from all over the world. The original Ghostbusters team are overrun with work and recruit new rookies to help out. 
In Ghostbusters: Sanctum of Slime, the story begins 4000 years ago with a strange cult mourning the death of Dumazu, an ancient demon of death and destruction. Fast forward to 1989, when museum curator Janosz Poha is sent to a mental institution following the events in Ghostbusters II. There he meets Ismael, the self-proclaimed last member of the cult of Dumazu. Ismael seeks a Shard of the Relic of Nilhe, a mystic artifact that possesses the power to bring Dumazu the Destroyer back to life, and he tasks Janosz with obtaining it. Janosz's reward: Dana Barrett.
Some years later, following Janosz’s release from the mental institution, a wave of unusual paranormal manifestations start appearing all over New York City. The Ghostbusters can't handle all the heat with this latest outbreak, so they recruit a young group of paranormal studies enthusiasts to lend a hand. And that's where you come in, guiding the rookie team in their first adventure to find the truth behind Ismael, the Relic of Nilhe, and Dumazu the Destroyer!
As Atari went into financial problems, a sequel to Ghostbusters: The Video Game went into limbo and Terminal Reality moved onto a Star Wars project. Atari went ahead and used the Ghostbusters license one more time. Sanctum of Slime was built in about four months. Environmental assets, such as the cemetery level assets, and character assets, such as ghosts, were reused from Ghostbusters: The Video Game. 
On December 7th, 2010, it was revealed publicly that the game was going to be released.
The original team does take part in the game and appears in the story sequences in-between the missions. However, they are non-playable characters.
As the player progresses through the levels, Egon invents new technology for the team and in the cut-scenes, presents new weapons to use that become important as they progress and meet new ghosts. One of the reasons for this is, Egon has discovered certain entities have specific colored auras around them and they are weak to certain types of energy. Players can switch to different colors and that weapon is stronger against that type of ghost. 
Another new character named Geoff is the driver. He meets the rookies at various points in the game to drive them around the city. In those driving sections they're all on the back of the Ecto-4WD chasing and being chased by lots of different types of ghosts.
There will be special combinations that will help in getting the high score in the game. As extra features, there will be collectibles, Achievements and Trophies. In multiplayer, when everyone is very close and aiming at the same ghosts, they can merge the streams, gain a power advantage, and also cause splash damage, which affects the ghosts in the surrounding area, as well. 
On February 9, 2011, a video preview indicated the first level will be the Sedgewick Hotel.
On February 15, 2011, it was revealed there will be 12 levels in the game. 
On February 16, 2011, Creative Director David Williams of the game developer Behaviour Santiago elaborated on gameplay. The rookies will use prototype weapons that Egon has been designing over the past decade. Egon's and Ray's studies on paranormal entities have revealed that ectoplasm can be charged with different sub-atomic charges and make entities weaker to different energy frequencies. These new weapons along with the enhanced Proton Stream can completely disintegrate minor entities and reduce the need for traps. However, when facing larger entities, the trap will be the main solution.
Disintegrated ghosts will usually leave a small trail of ectoplasmic residue that can be absorbed by the team's Proton Pack built-in Energy Syphon. In some situations, the energy left behind by the ghosts will be so powerful that they can power up some of the other energy consuming features of the Proton Pack, such as the Ectoplasmic Shield, Power Enhancer or Nano-Massage Health Recovery System.
On February 17, 2011, a Producer from Atari named Jonathan Moses revealed that Slimer will randomly appear in levels and the Stay-Puft Marshmallow Man has a "fun cameo." Also according to Moses, there are 14 levels, rather than the previously reported 12 levels. 
On February 24, 2011, at Microsoft Showcase 2011, Gamespot Editor-In-Chief reports there are 12 levels and 2 separate boss levels, including one for the Subway Smasher, verifying the earlier report of 14 levels. 
On February 28, 2011, it was revealed the familial connection will be between Janosz Poha and Alan Crendall. The specific connection is not yet known. And "At the very beginning of the game there's a scene with the classic Ghostbusters and the different characters like Janosz Poha." 
On March 11th, 2011, Jonathan Moses posted a video Development Diary and reveals the story begins 4000 years ago when Dumazu the Destroyer, a demonic deity, was buried. In the present, Dumazu is trying to get back to Earth and take over New York using "familiar Ghostbusters characters." 
On March 16th, 2011, six more screens from the game were released. One indicates the Stay Puft Marshmallow Man will at least appear as a power-up or collectible of some sort. 
On March 18th, 2011, Jonathan Moses reveals the Stay Puft Marshmallow Man are icons for hidden relics. They're hidden in breakable props within the levels. Alan Crendall was originally named Oscar, but that name and the story crafted for him didn't fit with other things that may be happening in the Ghostbusters lore. There are two different power-ups that will have contribute to a player's score. There is the multiplier that, while active, increases the amount a player receives for each ghost and item destroyed. The second power-up are bonus point pickups. There are also damage multipliers and shield icons. It is reconfirmed there are 12 levels in the game, not 14. There are demo versions or trials of the game for all platforms available (PC, XBLA, and PSN). The future of Ghostbusters in video games is being looked into by Atari. 
On May 31st, it was announced a Challenge Pack will be released on June 1st via Xbox Live and PC. It features two new modes of difficulty. Lone Hero is a single player mode and Arcade Challenge is a harder difficulty level. </ref>
On June 1st, a press release revealed more on the Challenge Pack. The Arcade Challenge gives a player a limited amount of lives and they play through five of the game's most challenging levels. In Lone Hero, a player can start any level they have unlocked but must play through alone without any AI team mates nor co-op. The Challenge Pack is available for for purchase at $1.99 or 160 Microsoft Points.

In the aftermath of the video game's release, it has come up on occasion in the Ghostbusters comics published by IDW, starting with the first issue of Volume One of the ongoing series. Sanctum of Slime is usually referenced in the form of hidden references on panels in the comic but characters have appeared. Most notably, in the prime universe, Alan Crendall made an appearance but is only a child, Ismael made a cameo appearance, and Bridget Gibbons' mother Kas made one appearance.
The entire junior team, in a separate parallel dimension, based on their designs in the video game made a brief appearance in two issues of the Ghostbusters: Get Real mini-series. In the third issue of Get Real, the Sanctum of Slime era is listed as the near future. Promotion for the Crossing Over maxi-series revealed the dimension inhabited by the team is designated "50-S".  It was revealed the team was assigned to small time hauntings at first and they never got a pay raise after defeating Dumazu.  The junior team was one of the allies Egon Spengler, from the prime dimension, recruited for help with trapping all of Connla's Army on Liberty Island. Soon after, they were one of the teams that came to help recapture entities missing from the Containment Unit. On September 28, 2018, it was announced there will be a one-shot issue starring the team in January 2019.
List of influences:
- In Ghostbusters Volume 1 Issue #1, a young Alan Crendall visits Winston and Janine at the Firehouse. He mistakenly equates Slimer's haunting of the apartment complex he lives at to a curse placed on his family for what his uncle, Janosz Poha, did.
- In Ghostbusters Volume 1 Issue #3, one of the easter egg references on the shelf is a blue gun by Peter that looks to be the Plasma Inductor.
- In Ghostbusters Volume 1 Issue #7, on the PCOC page, a post it note mentions calling Geoff at 555-8632 for a customization estimate for work to be done on Ecto-2.
- In Ghostbusters Volume 1 Issue #13, it is shown that Janosz and Ismael are incarcerated at the Parkview Psychiatric Hospital. Ismael is painting a mural as a nod to the painting of Dumazu's dimension. Above Ismael's mural are two photos of a shard of the Relic of Nilhe and one of the scepter held by the Cult of Dumazu leader in the opening cut scene. Loretta and the two attendants from the opening cut scene also appear.
- In Ghostbusters Volume 1 Issue #16, one of the ornaments hanging on the tree resembles the Relic of Nilhe. Idulnas threatens the life of Alan Crendall and his mother.
- In Ghostbusters Volume 2 Issue #3, one of the Parkview orderlies accompanies Kylie Griffin to Janosz' room.
- In Ghostbusters Volume 2 Issue #4, one of The Collectors takes on the form of an elder man in a wheelchair which is visually based on one of the Possessed Humans in the first Parkview level. The dormant Electroshock Construct to the left of Janine when she and Peter search a room. Between Winston and Melanie is the painting of Dumazu's dimension from the last level.
- In Ghostbusters Volume 2 Issue #18, Kas' last name is revealed on her credit card: Gibbons. This is the same last name as the Ghostbuster named Bridget. Kas turned out to be Bridget's mother in this continuity. Later in the issue, a side note on the Firehouse chalkboard reads, "Geoff RE: 4WD", referencing Geoff and the Ecto-4WD.
- In Ghostbusters: Get Real Issue #2, one of the portals the Cerberus Manifestation goes past in the upper left side features the junior team of Alan Crendall, Bridget Gibbons, Samuel Hazer, and Gabriel Sitter.
- In Ghostbusters: Get Real Issue #3, from pages 8 to 10, the near future of the IDW continuity was shown. The junior team and Geoff, as they appeared in the game, encounter the Cerberus Manifestation amid its search for The Real Ghostbusters.
- In Ghostbusters: Get Real Issue #4, on page 5, In panel 2 and 3, on the right, is the Employee of the Month board from Ghostbusters: The Video Game (Realistic Versions).

It is used again in Ghostbusters International Issue #10 on page 16 panel 5 on August again.
