The Last of Us Part II is a game Naughty Dog has been crafting for years that somehow managed to meet most people’s expectations. The issues people have tend to center on the game’s narrative choices, as opposed to the technical accomplishments and high level of quality displayed throughout.

Though The Last of Us is a more serious and somber when compared to most other mainstream gaming franchises, it isn’t without its fair share of silly Easter Eggs and cute references. Let’s now look at 10 Easter Eggs you might have missed your first time throughThe Last of Us Part II.

10 A Pearl Jam Poster

The Last of Us Part II features the use of Pearl Jam’s song titled “Future Days,” which Naughty Dog worked their tail off in an attempt to convince the band to let them use it. Fans immediately started question how the song would be known by Joel in the game when the album would have released after the events of the outbreak took place.

It turns out Pearl Jam played the song at a live concert months before its release. The band’s posters can be found in both a music shop early in the game, as well as in Dina and Ellie’s house during the title’s final hours.

9 PlayStation 3 Plus Some Games

Easter Eggs are usually details that are well hidden or only appear once, but the PlayStation 3 can be found several times throughout The Last of Us Part II. Alongside the large chunky original form factor of the console, players will also come across copies of the Jak & Daxter Collection, Uncharted, and Uncharted 2.

Why these specific games, though, and not something like Metal Gear Solid 4: Guns of the Patriots? That’s because they happen to be the most recent releases that Naughty Dog shipped before the outbreak occurred in the original game.

8 The Deus Ex Code

One of the safe combinations in The Last of Us Part II is 0451, which on the surface seems superfluous and unimportant. In reality, this is a nod to the Deus Ex series. The code has been used as an Easter Egg and reference in various forms of pop culture and entertainment outside of Naughty Dog’s landmark series.

The code itself will always unlock the first door in every Deus Ex game and is a bit of an inside joke among the series’ fans. These types of homages fit in nicely, as they don’t break the immersion of Ellie’s trek for vengeance unless you’re familiar with the niche reference.

7 Jak X: Combat Racing

Gaming as a hobby is so interesting because you can find people who love games you often considered to be afterthoughts. Jak X: Combat Racing is one of those titles, and it not only makes an appearance in The Last of Us Part II, but it also does so in a way that it never could have in real-life.

In the game, you can come across an arcade cabinet featuring the racing title, despite it only coming out on the PlayStation 2 in real-life. Most fans found it as a pleasant homage to one of Naughty Dog’s more underrated and underappreciated titles.

6 The Precursor Orb

That arcade cabinet wasn’t the only reference to the Jak & Daxter series in The Last of Us Part II. During the chapter known as “Hostile Territory” players can find and discover an object known as a strange artifact.

This strange artifact is the Precursor Orb, one of the main collectibles players search for and collect in the iconic series. It’s unclear if PlayStation will ever release a new game in the Jak & Daxter series, but it’s nice to see it get so much love from the franchise’s creators.

5 Hotline Miami On The PS Vita

Not only does The Last of Us Part II feature multiple scenes involving the beloved but under-performing PlayStation Vita handheld console, but the game being played on it is also an Easter Egg.

Right after Ellie is forced to kill the woman playing the PS Vita, players can zoom in on the screen of the handheld, which is now resting on the cement floor. Upon closer inspection, it becomes quite clear that the girl was playing Hotline Miami, a beloved top-down indie title released in 2012.

4 Dr. Uckmann Looks Familiar

One of the main collectibles in The Last of Us Part II are these trading cards Ellie can find throughout the world. They tie back to her interest in comic books and are a clever way to add references to things that don’t necessarily belong in the world Naughty Dog created.

One of the cards features a character named Dr. Uckmann, a play on the last name of Naughty Dog Vice President and The Last of Us Part II Game Director, Neil Druckmann. His card paints him as a mad genius, which seems a little on the nose.

3 The Giraffe Moment, Part II

Most fans of the original The Last of Us would tell you that the most memorable and emotionally engaging moments was when Joel and Ellie came upon a giraffe at an abandoned zoo. It featured Ellie getting the chance to pet a giraffe and showcased how childlike wonderment was still possible in a post-apocalyptic world.

In the sequel, there’s a flashback sequence where Joel and Ellie visit a museum on her birthday. Upon exploring the museum, players can enter a scene with a dinosaur fossil that frames itself in a way eerily similar to the iconic giraffe scene from the first game.

2 Nathan Drake’s Ring

Naughty Dog has a track record of including Easter Egg references to their other titles they’ve developed. Early in the game, Ellie and Dina come across a bank vault they can enter and inside they can find a mysterious ring.

This ring features the phrase “Sic Parvis Magna” which not only means “Greatness from small beginnings,” but is a notable possession of Uncharted’s protagonist, Nathan Drake. It’s unclear how the ring somehow ended up in a bank in Seattle and even less clear if and/or how both franchises are canonically tied to one another, but this is a cute little shout out nonetheless.

1 Sam’s Robot

Players who recently replayed The Last of Us before the release of The Last of Us Part II, or maybe just have solid memories of the former, are undoubtedly familiar with a boy named Sam. He was a young kid who survived with his father and they happened to have their stories intertwine with Joel and Ellie’s.

The robot toy Sam became attached to can be found in Ellie’s room in The Last of Us Part II. In the first game, she talks about forgetting to leave it on his grave and ends up keeping it in her possession as a result.
