Suicide Squad: Kill the Justice League is set in the same universe as Rocksteady's previous Batman: Arkham games, offering numerous references and Easter eggs that connect the series.
Despite its new setting and protagonists, Suicide Squad: Kill the Justice League is full of references to Rocksteady's previous Arkhamverse games, including Easter eggs and teasing of DC characters such as Superman, Green Arrow, or Blue Beetle.
After a tutorial in a decimated Metropolis, a flashback takes players back to the inception of Suicide Squad: Kill the Justice League. With an introduction reminiscent of Batman: Arkham Asylum's opening, the game introduces Waller and her team in an A.R.G.U.S. convoy to the iconic asylum, mirroring the Batmobile's arrival in Gotham. The Batman: Arkham Asylum score from that scene also establishes its connection to Rocksteady's Batman mythos.
When players are first introduced to Suicide Squad: Kill the Justice League's Task Force X, they are seen wearing Arkham Asylum and Belle Reve inmate uniforms, each clearly stating the inmate numbers of Harley Quinn, Deadshot, King Shark, and Captain Boomerang. These uniforms allow players to customize their characters' appearances throughout the game.
Suicide Squad: Kill the Justice League is all about the individual characters and their unique perspectives on the Arkhamverse's events. Identifying the perfect character to play can be challenging due to the vast and diverse range of personalities and skills represented within the team.
Each member of Task Force X has their own unique insights when interacting with the Arkham character displays. For example, when interacting with the Harley Quinn display as Harley, she will lament "Every gal has a phase she regrets, mine happened to get me consecutive life sentences," while looking at Joker's Titan transformation she will comment "I can't even say that's the most messed up thing he did." When looking at the Batman: Arkham City version of Deadshot as Suicide Squad: Kill the Justice League's version, Deadshot will call him a "phony steampunk-ass looking dude."
Every member will also have their own opinion on the display depicting Joker's death in Batman: Arkham City. Deadshot will simply say, "Ain't this supposed to be a family show?", King Shark will talk about "expiring in the arms of a superhero", and Boomerang compares it to his rivalry with Flash. Harley has the most personal and emotional reaction, considering her ties to Joker and how it impacted her in the Harley Quinn's Revenge DLC and Batman: Arkham Knight, and talks about how she coped by compartmentalizing her grief.Whereas most of The Batman Experience's displays are in the open and have interactive prompts to hear Jack Ryder's narration of the story behind each character or moment, there is a hidden display atop the church in the room that covers the events of Batman: Arkham Knight. If players climb to the top, they will suddenly be greeted by a pop-up Man-Bat standee and a screeching sound effect. This is a callback to the infamous Man-Bat jump scares in Batman: Arkham Knight.
When exploring the abandoned Daily Planet, Task Force X discovers several references to Superman lore, including desks of his colleagues and articles about his various colleagues' appearances. The newspaper front page titled "Demon Bat in Gotham" caught their attention due to its unusual headline that hints at Clark Kent's involvement in Batman's first appearance. The article, written by Superman himself, establishes the connection between Batman and Clark Kent, even though it was written decades before Batman: Arkham Origins and Suicide Squad: Kill the Justice League took place.
Two iconic DC actors, Kevin Conroy and Arleen Sorkin, are being honored in the Hall of Justice with two separate plaques. Each plaque will pay tribute to one of these remarkable actors and their contributions to the Batman universe.
Suicide Squad: KTJL, boasts an impressive roster of DC characters, with many actors reprising their roles from previous games.Shortly after defeating Flash, Task Force X is teleported to another universe's version of Metropolis, which has already been decimated by Brainiac. Here, they pick up a signal that suggests Lex Luthor may have survived and follow it to the ruins of the Hall of Justice. When entering this building, a sign for The Penguin's nightclub, The Iceberg Lounge, can be seen, suggesting that Earth 2's Penguin set up this business venture in Metropolis, rather than Gotham. Players could visit The Iceberg Lounge in Batman: Arkham City to fight Penguin.
Although Task Force X ends up on the other end of one of the Batman: Arkham Predator missions in "The Batman Experience", there are numerous references to his stealth tactics across Metropolis. Players can explore Wayne Bank, which was formerly an emergency shelter, and encounter open vent shafts surrounded by bullet holes and enemies strung up from grapple points. These references showcase the methods employed in the Batman: Arkham games to stealthily eliminate adversaries.
Batman's collected many of his enemies' belongings, including Deadshot's locker, which originally had the name "Deathstroke" on it. This name likely served as a playful dig at Deadshot, referencing his rivalry with Batman. Additionally, the locker's initial name could also be a nod to Batman's post-credits scene in Arkham Origins, where Deathstroke was approached by Waller as a potential candidate for Task Force X.
In pursuit of a way to stop Superman, Task Force X ventures into a hidden Batcave built beneath the Metropolis Hydro Power Station, revealing a treasure trove of Easter Eggs from the Batman: Arkham Origins training. holographic AR Challenges display a variety of challenges based on Batman: Arkham Origins training, while holographic replicas of Batman's Batmobile, Wayne Manor, and the Batwing are displayed alongside computers. A display case nearby showcases items stolen from prominent villains in the Arkhamverse, serving as a reminder of the villains' past exploits.

While Riddler's trophy and cane are on display in the Batcave, his hat can be found in the Hall of Justice before it's taken over by A.R.G.U.S. in Suicide Squad: Kill the Justice League.
