Legendary scientists
The Boomsday Project features nine labs full of crazy experiments, one for each class. Each lab is run by a Legendary scientist who embodies the ideals of their branch of science, often literally.


 * Boommaster Flark
 * Crystalsmith Kangor
 * Dr. Boom, Mad Genius
 * Dr. Morrigan
 * Electra Stormsurge
 * Flobbidinous Floop
 * Myra Rotspring
 * Stargazer Luna
 * Zerek, Master Cloner

Lore

 * Can you feel it? That electric tension on the wind, the reek of ozone and, the distant rumble of explosions; there's science in the air! Word around the inn is that Dr. Boom has returned to his secret laboratory in the Netherstorm. No one knows exactly what the mad genius will unleash, but a lot of very, VERY strange cards have found their way into decks around here lately: mechanical amalgamations, eerie crystals, revolting, lab-grown monstrosities… the good doctor and his esteemed colleagues are working on something big! Time to venture into the Netherstorm, find the lab, and uncover what these maniacs are up to.

In World of Warcraft

 * ''The is a region of northeastern  consisting of multiple large land fragments and shards of rock floating in the Twisting Nether. It was previously known as Farahlon (or the Fields or Plains of Farahlon), a lush island east of, until it was broken during the sundering of.


 * ''The Netherstorm is now locked in a constant magical storm bleeding from the Twisting Nether, further deterioriating the land. Magical lightning arcs within a thick haze of violet cloud and bands of pure magical energy wrap their way across the sky. Some of its wild creatures include s, mana wyrms, and.


 * ''When the ancient  was killed by the s, the bulk of its corpse formed a vibrant region later called Farahlon, which became a stronghold of the . Before the sundering of Draenor, Farahlon had a coastline on the . Besides the Primals, Farahlon was also home to some giants, and the presence of s in the Netherstorm indicate that more  might have had a presence in Farahlon.

Its isolated location also made it one of the few places on Draenor unaffected by  magic. After crossing the ocean with the help of ogre shipwrights, orc warlocks leeched life from the Primals and used the stolen power to set the island's dense forests alight while Kilrogg and his army slaughtered every  and  they could find.

Although the region was broken, Netherstorm was still comparable to  with its fields. But when the blood elves led by  reached Netherstorm, they captured Tempest Keep and used its machinery to harness the storm's magic, further compromising the already unstable land. They dismantled parts of Tempest Keep and strategically built five tremendous s across the Netherstorm, siphoning mana from the Twisting Nether itself and storing it in mana cells for the elves to feed on. The more energies they produced, the more unstable the region would become, turning Netherstorm into a barren, twisted wasteland. Over time, the manaforges weakened the fabric of reality in the Netherstorm, attracting the attention of the ethereals, who arrived on Outland to ply their trade or pursue their war against the . Thanks to  however, the forges were stopped soon enough preventing the entire destruction of Outland.


 * ''Several areas of the region have been influenced by goblins who performed research and experiments in the unique environment.

Announcing: The Boomsday Project

 * 'Have you yearned for an exciting career in SCIENCE?
 * 'Are you unburdened by a pesky sense of self-preservation?
 * 'Does it fill your heart with joy when stuff BLOWS UP?


 * ''If you answered “Yes!” or cackled maniacally in response to any of these questions, then YOU’VE got what it takes to join Dr. Boom’s team of brilliant scientists working on Hearthstone’s newest expansion: The Boomsday Project!


 * ''Read on to discover more about The Boomsday Project and the amazing opportunities that await YOU on campus when you join the Boom Labs team.


 * Our Founder
 * ''Operating out of Boom Labs—a secret world-class facility located in the beautiful, purple-lightning wracked floating islands of Netherstorm near Area 52—the Boomsday Project is the brainchild of the renowned Dr. Boom. Once a researcher at Area 52, Dr. Boom struck out alone and became a rising star in the fields of Mech design and rapid catastrophic disassembly.


 * ''Dr. Boom is at the top of his field, and the time is ripe to tackle new challenges. Enter The Boomsday Project, a multi-disciplinary research endeavor that’s sure to change the world—forever! Somehow. His team is still working out the details. . ..


 * Weird Scientists
 * ''When you accept a position at Boom Labs, you’re joining a team of the finest minds in cutting-edge SCIENCE! You’ll meet our wonderfully weird head scientists—technicians, engineers, biologists, theoreticians, and more—in the form of Legendary cards representing all nine Classes, including the esteemed Dr. Boom himself!


 * ''With the brilliance of these boffins at your beck and call, a break-through on The Boomsday Project is sure to follow!


 * Magic & Technology
 * ''Each of our head scientists specializes in a different S.T.E.M.* field, and Boom Labs is proud to unveil their most exciting innovation yet: Legendary spells! Every researcher has conceived of a Legendary spell suited to their unique talents—that’s one astounding new spell for each of the nine Classes.


 * ''With the unparalleled power of these Legendary spells at your fingertips, the Boomsday Project will be finished in no time—whatever it is!


 * Talent & Imagination
 * ''Science isn’t always about sleepless nights spent working in crazed solitude on highly questionable experiments. Occasionally, you’ll welcome unwilling participants to assist in your methodical madness! At Boom Labs, we know that two heads are better than one, and that sometimes, they’re on the same body!


 * ''There are new Project spell cards in several disciplines that benefit both you and your opponent. There’s still only room for one winner, though, so you’ll need to carefully measure your decisions.


 * Bits & Pieces
 * ''There’s no drudgery at Boom Labs! Need to handle volatile and mind-bogglingly dangerous experimental substances? Tired of carrying around your own nether-radioactive Omega fuel? Want to warm up your coffee in that magma chamber? Boom Labs’ army of Mech servants is your answer to every problem that requires a disposable solution! Their specialized arcano-electro-cerebrums allow them to think, feel, and do the drudge work, so you don’t have to**.


 * ''There’s no job too big or too dangerous for these mechanical marvels! Dr. Boom designed them with the new Magnetic keyword so they can snap together to tackle tougher tasks!


 * ''Simply place your Magnetic Mech to the left of a Mech you’ve already got on the board . . . and ZAP—they’ll combine ALL their stats and card text into a bigger, more powerful minion! Need them to stay independent? No problem. Just place your Mech down to the right of an existing Mech, and they’ll stay un-plugged to handle smaller tasks.


 * Shooting from the Hip
 * ''To ensure that no troublesome regulators or meddling do-gooders interfere with your work on The Boomsday Project, Dr. Boom has assigned Omega team to the defense of Boom Labs. This elite hench-unit has rapid response capabilities, but they’re at their best when their custom-designed Omega generators are at max capacity with 10 mana crystals fully charged!


 * Behind Bolted Doors
 * ''A LOT of SCIENCE happens at Boom Labs, and that means that there are dozens and dozens of unfinished or abandoned experiments hidden away in the complex. It’s a golden opportunity for a certain clever someone to figure out what the heck went wrong! Can you unravel their mysteries without exploding, dissolving, or becoming irrevocably poultry-ized forever?


 * ''When you experience The Boomsday Project’s free single-player content, The Puzzle Lab, you’ll discover that science is fun! And dangerous! Not necessarily in that order!


 * ''* Sabotage, Trickery, Explosions, and Mayhem


 * ** Guaranteed not to develop free will and destroy all organics!

 * ''Ah, another Boomsday Project update? Very well. Strike the preceding from the transcript.


 * ''My people, the Draenei, have always had a special kinship with the stars. They navigated through them, traveled among them . . . but their vision was always too narrow. Always intent on petty things like the, finding a new planet to inhabit, the survival of our species—rather than opening their eyes to the wonders that they could reach for and almost touch!


 * Come! Look! My grand observatory, so generously provided by Dr. Boom and Boom Labs, ''lies at the highest point in Netherstorm. Here we are ideally—uniquely—situated to study the mysteries of the universe. My work here involves much, much more than squinting through a telescope, as that multiplying moron Zerek claims.


 * If only you knew what lay beyond! In those vast reaches, the solution to every puzzle can be found. The patterns of the stars encompass all the mysteries of time and space. A study of celestial alignments reveals hints of cosmic horrors patiently hastening the inevitable heat death of the universe. Ah, it’s heavenly''!


 * Not all have the vision to appreciate it, sadly. My colleagues are consumed with paltry, material things. Resources. Power. Food. Sleep. Distractions! Why waste precious time on such things when the vast riddle of the heavens is written above, waiting to be unraveled? And controlled''!


 * ::microbot POK-E query::


 * ''Proof? Come closer, my little loose-screwed skeptic. Behold the tools of creation! An entire simulated galaxy: its energies tamed, its harmonies harnessed, and small enough to slip into a pocket. Is THAT good enough for Boom’s little project?


 * ::microbot POK-E query::


 * No, you insolent instrument. It’s not'' finished. There are still some irritating dimensional quirks to be resolved. But . . . if Boom can divert some funding, recruit more interns, and send over a few of your metal friends to help round up the strange creatures that keep appearing in my laboratory, I’m sure we’ll finish in time for whatever it is he’s planning.

The glorious greenery that surrounds you is just the beginning! Soon we’ll be growing super-sized versions of all sorts of vegetation. Hunger will be a thing of the past—not to mention the possibilities involved with the creation of entirely new, never-before-seen plant species!

 * Why, Kevin! You’ve been glooped! Quickly, if you just rinse off in the emergency show—ah, nope. It’s too late. He’s dissolved. I’m so terribly, terribly sorry. What an unfortunate incident! Poor Kevin. If only he was an advanced, ooze-based lifeform like myself, he might have avoided the gloop’s effects. We’d all be so much safer if we were all'' ooze-based. . . . Hm.


 * But look! My glorious gloop is glowing! Fascinating! In addition to its incredible properties as an ultra-fertilizer, I hypothesize that the gloop stores the potential energy of the matter it dissolves. A most curious side-effect, but doubtless of no interest to Dr. Boom. We’re here to solve real'' problems, after all.

As head meteorologist at Boom Labs, I’m proud to report that the Netherstorm is still there, filling the entire sky, and cascading countless bolts of delicious nether lightning at everything in sight. But I wasn’t sure how to channel all that lightning into a usable energy source. Then it STRUCK ME! Get it? STRUCK!?


 * ::microbot ZAP-R pained warble::

 * ::G4LV-NZR enthusiastic greeting::


 * ::G4LV-NZR query::


 * ''I am pleased to provide a status update on the progress of my experiments. An organized system is a more perfect system.


 * ''My people, the ethereals, lost our corporeal forms long ago, becoming energy-based beings in the process. While that offers many advantages over our sloppy, meat-based counterparts, it presents challenges in others. I’ve spent much of my life searching for a way to ensure the survival of our most important personage: myself. The answer? Cloning!


 * ::G4LV-NZR query::


 * My work has progressed swiftly. The chamber in which we stand houses my Cloning Gallery: row upon row of cloning chambers, each capable of growing duplicates of an encyclopedic array of beings on demand. With the power of this facility, I can produce an army of those clones at will, and my proprietary process allows them to grow to full maturity at a vastly'' accelerated rate.


 * ::G4LV-NZR bemused observation::


 * ''I’m aware of that! I said “maturity,” not “size.” When produced en masse, they are much smaller than usual and regrettably moist. And leper gnomes are always small and moist.


 * ::G4LV-NZR metallic snickering::


 * If perfection was easy'', everyone would do it!


 * This is an enormous undertaking, mech—I can’t be everywhere at once! Yet''. That’s why we’re here, after all. Cloning biologicals is simple. As an energy-based life form, cloning a perfect version of myself has proven . . . challenging. My current assistant is less methodical than I’d like.


 * ''Please relay to Dr. Boom that I require an assistant with the wit and precision for the work at hand. And if they manage to meet my expectations? Well, I’ll make more.

 * ::G4LV-NZR enthusiastic greeting::


 * ''Well. You’re disgustingly cheery.


 * ::G4LV-NZR perky query::


 * Fine. I’ll divert my attention away from my vital research to waste time discussing my work with an appliance who won’t comprehend it, so you can report it to someone who won’t listen, so he can decide whether my work is up to standards that haven’t been set, because he never understood what I was working on to begin with. Does that sum things up? Hm?''


 * ::G4LV-NZR cheerful affirmative::


 * ''Guh.


 * In life, when I could still taste, feel, and experience happiness, I wasted precious hours studying mathematics. As a banshee, I chose to research a less unsavory subject: the emancipation, analysis, and practical application of souls. I have founded an entirely new field of study. I call it Soulology''!


 * ''I’ve approached my studies methodically and precisely. What I’ve learned has enabled me to develop entirely new technologies to cheaply and efficiently harvest souls, refine them, and then focus them into to their purest essence. And I can do it with finer precision and with greater care than the clumsy manipulations managed by most Warlocks.


 * ''BEHOLD THE SOULARIUM


 * While the living are . . . crude'' in their base form, the souls they contain are truly remarkable! Once freed from their fleshy prisons, they soar free to become a readily accessible energy source far richer and more versatile than Stormsurge’s ludicrous light shows. And there are other perks as well: terrifyingly powerful weapons! Vast amounts of information delivered instantly! Fewer gnomes!


 * ''I’ve even developed a prototype that allows for soul essence transposition. Why travel from place to place, when you can simply swap essence with another creature that is already where you wish to be?


 * ::G4LV-NZR doubtful query::


 * ''Of course, there are always challenges. . . . Zerek has been helpful, but I could always use more test subjects. And the souls are remarkably persistent in maintaining a connection with their erstwhile hosts. Also, while the Soularium grants access to impressive stores of knowledge, the sudden catastrophic memory loss is—admittedly—something of an inconvenience.


 * ''Still, I’m certain that Dr. Boom will agree that what I’ve accomplished here is among the most important breakthroughs in Boom Labs. Now, fetch me some more gnomes. I have work to do.

Comics
A series of free web comics following the adventures of Dr. Boom was released a few weeks prior to the release of The Boomsday Project. The first issue, Lowering the Boom, was released on July 21, 2018.

Development
Senior Game Designer Peter Whalen describes the creation and overall themes of The Boomsday Project as follows:
 * "Every expansion starts with an idea: dinosaurs, werewolves, the Lich King. In this case, it was science. We wanted to make an expansion that captured the sense of wonder you feel when you look up at the stars, or when you mix baking soda in vinegar and watch it bubble over. We wanted silly explosions, giant plants, and hordes of cloned leper gnomes. For our science expansion, we needed someone special, someone beloved by Hearthstone players everywhere: Dr. Boom. Last seen in Goblins vs Gnomes'', he's been busy. He's built a secret base in the Netherstorm, filled with the greatest minds on Azeroth. Well, at least the ones with no sense of self-preservation.
 * "And so the setting started to take shape. We'd have nine different labs, one for each class, catering to a different type of science. Mages are astronomers, shaman meteorologists. We started off with warlocks as mathematicians (math being, of course, the most evil of all the sciences), but we ended up shifting them into researching souls. Goblins vs Gnomes had embraced one aspect of science — the explosive bit — but The Boomsday Project'' takes on all of it.
 * "We had the flavor for the science set. How were we going to capture it in the cards? Every expansion has a mechanical personality. Journey to Un'Goro was the dinosaur set. It had oversized rewards in giant, powerful cards. Knights of the Frozen Throne was about being sinister. It had cards like Skulking Geist and Gnomeferatu that let you mess with your opponent more than usual. The Boomsday Project is about science. We want you to feel like a mad scientist, combining cards in wild and wacky ways. Magnetic lets you glue your minions together, Omega cards encourage careful planning, and crazy gadgets lead to all sorts of silly hijinks."

The expansion that became The Boomsday Project did not begin with the idea of featuring Dr. Boom as a central character. Instead, the creation of the set began with a desire to base an expansion around science and "giant robots punching each other". This led to the question of what the expansion's setting and central character would be. The Netherstorm made a lot of sense for the setting due to the large amount of science occurring in the World of Warcraft version of the zone, and in turn, Dr. Boom made sense as the expansion's main character.

As a way of calling back to the history of Dr. Boom, Blizzard wanted to tie The Boomsday Project and Goblins vs Gnomes together to a small extent. Thus, there are a handful of cards in The Boomsday Project that are reminiscent of cards from Goblins vs Gnomes.

When Blizzard started work on The Boomsday Project, they knew they wanted to bring the Mech minion type back in a big way and searched for a mechanic that celebrated Mechs but also felt different from the Mechs in Goblins vs Gnomes, the expansion that first introduced the minion type. They initially had the idea of Mechs that could "plug-and-play" into each other, leading to the creation of a minion mechanic called Modular with various experimental implementations. One version of Modular was a type of Choose One effect which presented the player with a choice of playing the card as a minion or attaching it to an existing minion as an enchantment. However, it felt overly clunky having to choose each time one played a Modular card. Ultimately, one designer had the idea of Modular minions being "sticky": they would attach to existing Mechs if played next to them, but would function as standalone minions if they weren't. The team iterated on the idea and came up with directional implementation, which acts like magnetic poles. From there, they changed the name of the Modular mechanic to Magnetic to better explain its functionality.

The idea of legendary spells came about when Blizzard wanted to capture the feeling of science and crazy inventions. They hit on the idea of having scientists in each of the classes, along with legendary spells representing the scientists' life's work and main discovery. Legendary spells are distinguished from other spells by being "big", "flashy", "cool", and "unique", with several having effects that players would only want a single copy of in their deck (such as Luna's Pocket Galaxy).

Teasers and announcement
The Boomsday Project was first teased on February 27th, 2018, when Blizzard announced the changes and new content planned for the Year of the Raven, the third year of standard format. The announcement blog post and accompanying video included a teaser image for the planned three expansions of the year, with the second expansion being denoted with an image depicting what appeared to be an ethereal portal in the.

On July 9th, 2018, the day before the expansion's announcement, the official Hearthstone Twitter account posted an image of a sign indicating an emergency eye wash station. On the same day, the official Russian Twitter account posted a slightly different image along the same theme.

On the following day of July 10th, the official announcement video for The Boomsday Project (shown below) briefly appeared on the Hearthstone YouTube channel before being made unlisted, prematurely revealing the expansion. A few hours later, the video reappeared and the expansion was officially announced.

Card reveals
Following the initial announcement of the expansion, cards from the set began being revealed through official blog posts and videos posted by Blizzard. Card reveals from press and members of the Hearthstone community began following a card reveal livestream featuring Senior Game Designer Peter Whalen and caster Brian "bmkibler" Kibler on July 23, 2018. The final card reveal livestream, featuring Game Designer Mike Donais and Sean "Day[9]" Plott, took place on August 1, after which all of the the remaining cards from the set were revealed on the official Hearthstone Facebook page.

Over the weekend of August 4-5, a few days prior to the full launch of the expansion, players had the opportunity to attend special Pre-Release Fireside Gatherings in select locations around the world, allowing them to open their The Boomsday Project card packs early and play with the cards from the new expansion in special Fireside Brawls.

Trivia

 * The Boomsday Project appears to have been foreshadowed in the preceding expansion, The Witchwood: the Monster Hunt boss Experiment 3C has several quotes alluding to Dr. Boom, a lab, and the.
