Netflix's Stranger Things S4 easter eggs.

Following the Netflix release of the show's first season in July 2016, the Stranger Things Expanded Universe started in October 2017, when the first video game dropped just before the second season, and then laid fallow for nearly a year. Then, in September 2018, Netflix and its publishing partners hit the gas pedal, releasing new titles at an almost breakneck speed – now, there are three novels, two comic-book miniseries, and a veritable slew of behind-the-scenes materials to accompany that first single mobile game, and even Stranger Things 3: The Game, which came out the same day as the third season.

There’s a lot to untangle here – and a lot to unpack, narratively and thematically. The more that the writers behind the Stranger Things EU excavate the show’s past, digging into its characters and conjuring up new adventures before the Upside Down invaded Hawkins, Indiana, the more story possibilities unfold, meaning that fans of the TV show will be hard-pressed to run out of retro material, no matter how long of a gap there may be between batches of episodes. Here is the perfect way to experience everything that is the Stranger Things full timeline.

1. Stranger Things: Suspicious Minds

  • Format: Novel
  • Release date: February 2019

Set 13 years before Stranger Things season 1, Suspicious Minds covers the most formidable period in the Stranger Things full timeline. It begins in June 1969 and ends in November 1970, with baby Jane Ives already some five months old. With the Hawkins National Laboratory having just been completed, and with Brenner having just arrived with test subject Eight in tow, the stage is set for the recruitment of Terry Ives, Eleven’s mother, and a haphazard crew of other Hawkins Lab kid experiments – the individuals who will first discover the Void (the telepathic area that exists between our world and the Mind Flayer’s) and get glimpses of the Upside Down and the Demogorgons that reside there.

Along the way, Terry forms a bond with her fellow subjects that’s not unlike Mike Wheeler’s fellowship with his three middle-school pals and comes to be pregnant with the future Eleven. She succeeds in freeing at least one of her newfound friends from the icy clutches of Brenner, but she fails in busting Eight out of her new prison – or from preventing the mad doctor from snatching her newborn baby away from her.

2. Stranger Things: Six

  • Format: Four-issue comic book miniseries
  • Release date: May to August 2019

Taking place in 1978, the comic miniseries Stranger Things: SIX, switches the focus to test subject Six, a character never before seen (or, even, heard of) on-screen. Whereas Eleven has telekinesis and Kali, a.k.a. Eight can project illusions into individuals’ minds, the teenager formerly known as Francine is able to see brief snippets of the future and, at times, act upon them – the perfect weapon for Dr. Brenner to brandish against the Soviets.

Stranger Things: SIX is Francine's only appearance in the Stranger Things Expanded Universe, as she was replaced in Stranger Things season 4 by De'Jon Watts' character Six. This inconsistency, which also extends to Hawkins Lab experiment Nine introduced, is a bit of a gaping hole, but the comic miniseries does deliver on some interesting backstory tidbits. Certainly, it's worth a read.

3. Stranger Things Season 1

  • Release date: July 15, 2016

The Stranger Things full timeline begins in earnest with season 1. These first eight episodes introduce viewers to the property’s premise, characters, tone, themes, and – perhaps most importantly for Expanded Universe purposes – the backstory. Season 1 offers the franchise's first tastes of things like the Upside Down, Stranger Things' plethora of D & D references, and the core cast that make up the main timeline's central story.

4. Stranger Things: The Other Side

  • Format: Four-issue comic book miniseries
  • Release date: September 2018 to January 2019

Stranger Things' four-issue comic-book miniseries – collected in trade paperback form as Stranger Things: The Other Side – tells the story of season 1 from the perspective of Will Byers as he’s lost in the Upside Down. Stranger Things' first foray into the printed page both impresses and falters. On the one hand, this comic is as much a loving throwback to the ‘80s as is its television progenitor, replete with faux-retro art and thought balloons to express Will’s inner monologue (the trend in comics scriptwriting long ago switched to using captions instead of the cheesy, fluffy balloons). The story is filled with loving references to season 1 – and, in the end, just possibly a piece of foreshadowing or two for the second and third seasons, including a sly reference to the Mind Flayer.

On the other hand, there is no real story to speak of, with the plot feeling more like a list of references to be checked off than a living, breathing entity. While it is neat to see how Will is able to psychologically survive in the Upside Down, one can’t help but feel like the finished product was some two or three issues too long, at the least.

5. Stranger Things: The Game

Stranger Things the Game
  • Format: Mobile game
  • Release date: October 4, 2017

Designed as a loving homage to the 8-bit classics that reigned supreme in the ‘80s, most specifically The Legend of Zelda, the free-to-play Stranger Things: The Game does fit into the property’s overarching mythology, but it plays a bit fast and loose with its contents – again, not unlike the Nintendo Entertainment System adaptations of the big movies of the day. Players start off controlling Police Chief Jim Hopper and eventually accrue nearly all of the cast’s underage characters, starting with Lucas Sinclair and ending with Eleven (a secret unlockable character).

Most of the kids have suddenly gone missing, and Hopper quickly deduces that the Hawkins National Lab is at the heart of the misery yet again, as a number of small portals between the everyday world and the Upside Down have begun to emanate from there once more. By the game’s end, not only has everyone been recovered, but there are even a few pieces of Stranger Things season 2 foreshadowing introduced, such as the emergence of Bob Newby and Billy Hargrove on the scene. There was even an update after season 2 arrived, adding in an extra dungeon and allowing Max Mayfield to be a playable character – somewhat breaking the continuity of the show but nonetheless proving to be a fun gameplay addition.

6. Stranger Things season 2

  • Format: TV series
  • Release date: October 27, 2017

With all of the Expanded Universe materials now firmly in hand, Stranger Things season 2's contents are rendered all the more dramatic: the revelation of how Terry Ives ends up in a catatonic state is more heartbreakingly climactic as opposed to being purely expository; Eight is less part of a perceived dead-end storyline and becomes more of an emotionally-engaged figure; and the Hawkins National Laboratory’s demise lands all the more heavily, given just how much more time readers have spent in its halls and seeing how its various residents have been treated.

BONUS: Beyond Stranger Things

  • Format: TV series
  • Release date: October 27, 2017

Before getting to even more expanded adventures set within Hawkins, Indiana, there’s a slight detour to be had first. Beyond Stranger Things is an after-show, though it’s slightly different than its brethren in that it’s designed to be watched only after the entirety of its companion season has been completed (that is to say, watch all of Stranger Things season 2, then binge Beyond straight through). These seven short episodes, hosted by actor Jim Rash, trot out the creators-showrunners the Duffer brothers along with a number of the cast and crew to discuss key developments from the second season of the source material, all in a set that is exceptionally pitch-perfect (and with an intro that is also satisfactorily ‘80s).

7. Stranger Things: Runaway Max

Billy and Max in Stranger Things
  • Format: Novel
  • Release date: June 2019

Just as the Stranger Things comic miniseries retold the story of the first season from a different perspective, Stranger Things: Runaway Max does the same exact thing for the second. This young-adult novel does things a bit differently from its two book compatriots – its target audience is younger, its page count is way shorter, its narrative scope is more limited, and its usage of the first person is, thus far, unique. It starts only a few days before Stranger Things season 2 and ends concurrently with it, delivering its brand-new material – Max Mayfield’s home life, her relationships with her deadbeat father and crazed step-brother (including what made them pack up and move to Indiana), and her continued efforts to run away from Hawkins for the greener pastures of LA – almost exclusively in the form of flashbacks.

8. Stranger Things: Darkness on the Edge of Town

Stranger Things season 2 Hopper
  • Format: Novel
  • Release date: May 2019

It is December 26, 1984 – just a few weeks after Stranger Things season 2 – and as Jim Hopper and Eleven wait out a bad snowstorm, El decides to pull out a box from Hop’s days as a New York City homicide detective and make her newly-legally-minted father tell her the story about the time that he chased down a bizarre serial killer. Stranger Things: Darkness on the Edge of Town is set in July 1977, at a place and with characters that have very little bearing upon the Stranger Things full timeline – if any bearing at all, that is. Therefore, it's truly a standalone story.

However, even with that said, the novel is well-written and paced, and it so perfectly captures Hopper’s voice and character, it’s hard not to fall in love with it. When combined with the emotional nature of the story – it ends on Christmas ’77, the last holiday that Hopper and his family would ever spend together, as just one for-instance – it’s hard not to regard Darkness on the Edge of Town as anything other than a sheer, unadulterated homerun and some of the best time that one can spend in the world outside of Stranger Things' Hawkins and the Upside Down.

BONUS: Stranger Things: Worlds Turned Upside Down

Stranger-Things-Shawn-Levy-Duffer-Brothers
  • Format: Book
  • Release date: October 2018

Part behind-the-scenes tell-all and part coffee-table book, Worlds Turned Upside Down doesn’t do either perfectly – and yet, in this interesting intermix, it still manages to be a compelling page-turner, alternatively offering up interesting tidbits about Stranger Things’ very earliest conceptualizations by the Duffer brothers and providing beautiful double-page photographic spreads of the actors, their costumes, and the sets they inhabit.

Just as the comics play up the retro shtick by featuring dated artwork and worn-looking covers, this companion book goes the extra mile, including a dog-eared appearance and, even, a sticker from Melvald’s General Store (where Joyce Beyers works and where audiences can explore in Stranger Things: The Game). Beyond that, it includes a map of Hawkins and a Morse code decoder, which readers could use to decipher a rather cryptic clue as to what the then- Stranger Things season 3 held– just the first in many such tidbits in this regard (including some that come straight from the mouths of Matt and Ross Duffer).
