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.
