Kendrick Lamar's Super Bowl halftime show Easter eggs, from PlayStation to Drake

Kendrick Lamar left fans with plenty to unpack after his stunning Super Bowl halftime show performance.

The Pulitzer Prize-winning rapper took his beef withDrake to one of the biggest stages in music on Sunday with a set that included his massively popular "Not Like Us." The song sprung out of a feud between the two rappers and is a diss track explicitly calling out Drake, whom Lamar name-checked during the halftime show while grinning and looking directly at the camera.

But the performance was also filled with less obvious symbolism and Easter eggs, some of which tied into a video game theme and a few of which may get Drake's blood boiling even further.

The meaning behind Kendrick Lamar's 'a' necklace

The lowercase "a" necklace that Lamar wore throughout his performance appeared to be a reference to the logo of pgLang, the company he founded with Dave Free.

But intentional or not, fans thought the necklace might also be a sneaky reference to the most brutal lyric in "Not Like Us," in which Lamar raps that Drake is "trying to strike a chord and it's probably a minor."

How Kendrick Lamar's set referenced the PlayStation controller

The performance ended with the words "GAME OVER" being spelled out in the crowd, likely to imply that Lamar's feud with Drake has officially ended and that he is the victor.

It also tied into a broader video game theme throughout the set. In fact, art director Shelley Rodgers told Wired that each of Lamar's performance spaces were inspired by the PlayStation controller, which features a triangle, square, circle and X button.

"I think the (video game theme) was symbolic, his way to reach young people," Rodgers told Wired. "A lot of it is showing his journey, traveling through the American dream."

Kendrick Lamar spells out 'WARNING WRONG WAY'

A more subtle message that appeared in lights in the crowd spelled out "WARNING WRONG WAY."

The meaning of the message is open to interpretation, but one fan on Reddit theorized it meant that the United States is moving in the wrong direction. Others suggested it meant that Lamar was going in the wrong direction with his performance compared to what Uncle Sam wanted. As portrayed by Samuel L. Jackson, Uncle Sam scolded Lamar for his set being "too loud, too reckless, too ghetto."

Kendrick Lamar's 'Gloria' jacket

Lamar wore a custom Martine Rose jacket that read "Gloria" for the performance, a reference to the closing song of the same name from his album "GNX." The track, which featured SZA, has been interpreted as a metaphor for the power of Lamar's lyricism.

Kendrick Lamar brings out two of Drake's exes

Lamar's performance didn't just call out Drake by name but featured not one, but two of the rapper's exes.

Lamar's special guest for the performance was SZA, who Drake briefly dated. But that's not all: Serena Williams also made a cameo in the performance, performing a crip walk during "Not Like Us." Drake previously dated Williams around 2015, and she's name-dropped in "Not Like Us" when Lamar warns Drake he "better not speak on Serena."

The tennis star sparked controversy in 2012 when she did the same dance during the London Olympics tennis matches in Wimbledon following her defeat of Maria Sharapova. At the time, critics felt the dance glorified gang violence, while fans defending Williams felt the outcry was racially motivated.

An excited Williams referenced just that in a clip on X: "Man, I did not crip walk like that at Wimbledon," she laughed. "Ooo, I would've been fined."

The symbolism of the American Flag during Kendrick Lamar's performance

One of the most striking images from the performance was Lamar surrounded by Black dancers dressed in red, white and blue to resemble the American flag. The image suggested that the United States is "built on the backs of Black people," as X user Alex Cole observed. Lamar stood in the middle of a flag that was divided into two sides, each of which had their backs turned to each other at one point.

Kendrick Lamar references Drake's 'Not Like Us' lawsuits

Drake has taken his issues with "Not Like Us" to court, in January filing a federal lawsuit against Universal Music Group over the diss track that accuses him of being a pedophile.

Lamar referenced this during the halftime show when he teased a performance of "Not Like Us" and declared, "I want to perform they favorite song, but you know they love to sue."

Kendrick Lamar drops the most inflammatory lyric from 'Not Like Us'

Potentially in an effort to avoid more legal action, Lamar's "Not Like Us" performance was missing a key lyric.

In the original song, Lamar explicitly called Drake a pedophile, rapping, in reference to Drake's album "Certified Lover Boy," "Certified lover boy? Certified pedophiles." During the Super Bowl performance, Lamar rapped this lyric but dropped the word "pedophiles."

But that's not to say Lamar went easy on Drake, considering he still kept the lyric, "Say, Drake, I hear you like them young."

Kendrick Lamar references '40 acres and a mule' in 'Not Like Us'

During his performance of "Not Like Us," Lamar referenced "40 acres and a mule," telling his backup dancers, "This is bigger than the music."

40 acres and a mule refers to Gen. William T. Sherman's formal attempt at reparations for formerly enslaved Black Americans in 1865 during the Reconstruction era. The offer was intended to spur Black American economic prosperity post-Civil War. The offer was never fulfilled, though the conversation has resurfaced in many forms in the decades since, including in Lamar's home state.

Lamar previously rapped about "40 acres" in his tracks "Wesley's Theory" and "For Free" from his 2015 album "To Pimp a Butterfly," a project that touches on oppression, inequality, justice and more political commentary. In "Wesley's Theory," he alludes to the illusion of prosperity for Black Americans, stating: "What, you want you a house or a car? / Forty acres and a mule, a piano, a guitar? / Anything, see, my name is Uncle Sam, I'm your dog."
