Source plot synopsis — includes the ending
The narrative of the game continues from where Marvel's Spider-Man and its downloadable content The City That Never Sleeps left off, during which Miles Morales (Nadji Jeter) was bitten by a genetically enhanced spider and gained powers similar to his mentor and friend Peter Parker (Yuri Lowenthal). A year after the first game's conclusion, Miles has been trained by Peter, moved from Brooklyn to Harlem, and has fully integrated himself into the role of a Spider-Man. He is still in the process of gaining experience and doubts whether he can live up to Peter's legacy. At the beginning of the game, Peter leaves New York for Symkaria for several weeks to help his girlfriend Mary Jane Watson with her reporting there and trusts Miles to protect the city in his absence. Now the sole Spider-Man, Miles must balance his superhero responsibilities with supporting his mother Rio Morales (Jacqueline Piñol) in her campaign for City Council and defending his new home from a violent war between the corrupt Roxxon Energy Corporation and a high-tech criminal army known as the Underground.
Aside from Miles, Peter, and Rio, the game features several other returning characters from Marvel's Spider-Man, including the supervillain Rhino (Fred Tatasciore), the imprisoned crime lord Wilson Fisk (Travis Willingham), anti-Spider-Man podcast host J. Jonah Jameson (Darin De Paul), and F.E.A.S.T. volunteer Gloria Davila (Melanie Minichino). Peter's former mentor and employer Dr. Otto Octavius (William Salyers) appears in a flashback, while the head of Oscorp and former New York mayor Norman Osborn (Mark Rolston) appears in a mid-credits scene. Miles's late father, Officer Jefferson Davis (Russell Richardson), appears in a voice-only role. Norman's son Harry is also featured in a non-speaking appearance in the mid-credits scene via a first-person perspective.
The new cast includes Miles' best friend and classmate Ganke Lee (Griffin Puatu), who is aware of his secret identity and assists him with his Spider-Man activities; Miles' estranged and overprotective uncle Aaron Davis (Ike Amadi), who leads a double life as the armored mercenary Prowler; the head of Roxxon's R&D department Simon Krieger (Troy Baker); podcaster and Spider-Man supporter Danika Hart (Ashly Burch); deaf street artist Hailey Cooper (Natasha Ofili); bodega owner Teo Alvarez (Yancey Arias); Caleb's Clean Cuts barber Caleb Ward (Emerson Brooks); Pana Fuerte restaurateur Camila Vasquez (Krizia Bajos); and Miles' childhood best friend Phin Mason (Jasmin Savoy Brown), as the Tinkerer, the figurehead of the Underground, who seeks to avenge her brother Rick. The mid-credits scene introduces Dr. Curt Connors, who is voiced by an uncredited actor.
Plot
After more than a year of training under Peter Parker, Miles Morales has mastered his superpowers and established himself as the original Spider-Man's crime-fighting partner, though he still struggles to adapt to his new role. While he and Peter escort a police transport carrying prisoners to the rebuilt Raft, Miles accidentally releases several inmates, including Rhino. While trying to stop Rhino's rampage through the city, Peter is knocked unconscious. Miles intervenes to protect him and defeats Rhino with his new bio-electric ability, later dubbed "Venom Blast". Leaving Rhino in the custody of energy corporation Roxxon, headed by Simon Krieger, Peter informs Miles that he will be going to Symkaria for a few weeks to assist Mary Jane Watson as her photographer as she writes a story on the country's civil war, and entrusts Miles to look after New York in his absence as its sole Spider-Man. Later, Miles investigates a break-in at Roxxon Plaza and stops a hi-tech criminal group called the Underground from stealing Roxxon's new experimental power source, Nuform. Returning home to celebrate Christmas with Rio and Ganke, Miles is surprised to learn that Rio also invited his childhood friend Phin, with whom he has not spoken in months. The next day, Ganke creates a Spider-Man app so citizens can call Miles for help directly. Miles' uncle, Aaron Davis, is the first to use it and reveals that he knows his nephew's identity as Spider-Man.
Miles soon witnesses the conflict between the Underground and Roxxon escalate, as the former attack one of Rio's campaign rallies in front of Roxxon Plaza and a Roxxon transport carrying Nuform on the Braithwaite Bridge. Miles tries to prevent the Underground from stealing the Nuform, discovering Phin is the Tinkerer in the process, but his Venom Power causes most of the Nuform to explode, destroying the bridge and damaging his public image. Ganke gives him a pep talk and reminds Miles that for now, he is New York's only Spider-Man, encouraging Miles to become better and make his own unique Spider-Man costume in the process. While investigating Phin's connection to the Underground, Miles discovers that her brother Rick created Nuform during his work for Roxxon, but soon became sick due to its unstable properties. Phin and Rick sought to expose the dangers of Nuform to the public, but while trying to shut down a Nuform reactor, the latter was killed by Krieger, who subsequently took credit for Nuform's creation. With Aaron as the Prowler, Miles infiltrates a Roxxon lab to retrieve Phin's phone, which contains evidence of Krieger's crimes, but the phone is destroyed during his escape.
At Aaron's advice, Miles uses his friendship with Phin to infiltrate the Underground and learn more about their plans. He discovers that Phin created the Underground's advanced weaponry out of a special component, programmable matter, in exchange for their help in exacting revenge on Krieger, which she plans to achieve by sabotaging the Nuform reactor at Roxxon Plaza to destroy it and expose Nuform's dangerous side effects. However, Miles is soon forced to reveal his identity as Spider-Man to Phin in order to save his own life, souring their friendship. While meeting with Phin to try and reconcile with her, the two are captured by Roxxon with the aid of Rhino, whose exosuit has been enhanced by Roxxon tech. Miles and Phin escape, but the former learns that Aaron has been spying on him for Roxxon and that Krieger modified the plaza's Nuform reactor to destroy Harlem if Phin's plan succeeds. After being defeated, Rhino taunts Phin about Rick's death, causing her to viciously attack him. Miles intervenes to stop her from killing Rhino, but a furious Phin escapes after knocking Miles out.
Ganke brings an injured Miles home, where Rio discovers her son's identity as Spider-Man, but continues to support him. After recovering, Miles heads off to stop Phin, but is captured by Aaron, who imprisons him underground to prevent him from being killed like his father, Jefferson Davis, whom Aaron was unable to reconcile with prior to his death, resulting in his overprotectiveness of Miles. Miles escapes and defeats Aaron, explaining that he cannot turn his back on people when they need him. Inspired by his nephew's words, Aaron assists Rio with evacuating Harlem as the Underground and Roxxon fight on the streets, allowing Miles to head to Roxxon Plaza to stop Phin. Unable to reason with Phin, Miles fights and overpowers her before attempting to absorb the Nuform from the reactor to negate the blast, but the amount of energy proves too much to handle. Realizing her errors, Phin flies Miles to a safe distance above the city so that he can release the energy, killing her in the process. Miles plummets to the ground, where his identity is exposed to a few citizens he helped as Spider-Man, who promise to keep his secret and hail him as a hero.
Four weeks later, Roxxon is dealt numerous lawsuits, and Krieger is arrested after Aaron turns himself in and testifies against Krieger. Peter returns home from Symkaria and praises Miles for his growth and heroism, before they head off to fight crime together as the Spider-Men. In a mid-credits scene, Norman Osborn orders a reluctant Curt Connors to release his terminally ill son Harry Osborn from stasis despite the latter's unstable condition. In a post-credits scene, Miles leaves an award he won with Phin atop Trinity Church in her memory.
