Mission

Missions on this wiki are defined as the single-player Solo Adventures that contain missions within them and are different from Adventures because they reward card packs rather than collectible cards. Like in Adventures, the player participates in boss battles played against computer-controlled opponents. These battles are designed to develop an expansion's lore and narrative. Nearly all Missions are free for the player to play.

The first Mission to be introduced was Icecrown, the Lich King missions from the Knights of the Frozen Throne expansion.

To gain access to Missions in Wild format, players need to claim them for free in "Shop" section on Blizzard's official website.

Wild-format Missions
The following Missions have rotated into Wild format, and become playable after a player has opened their first pack of the respective card set.

Knights of the Frozen Throne


Knights of the Frozen Throne is the first Hearthstone expansion to include Missions, released August 10, 2017.

The Missions see the player ascend through the dreaded, home to the Lich King and his. The Missions feature a total of 8 bosses, spread across three wings and an introductory Prologue. Completing the Prologue rewards a random Knights of the Frozen Throne hero card, while completing every subsequent wing rewards 1 Knights of the Frozen Throne card pack each. Defeating the final boss encounter, The Lich King, with all 9 original classes rewards the Arthas Menethil alternate paladin hero.

Dungeon Run
Dungeon Run first of the new style of Missions as part of Kobolds & Catacombs, released December 7, 2017.

This mode has the player venture through the catacombs, a vast underground world of tunnels dug out by kobolds and other subterranean creatures. Dungeon Run features a large, randomized pool of bosses, ensuring every playthrough is a little different. Rather than build their own decks, players start with a small number of cards and collect more cards after each won encounter. They also collect treasures, which are extremely powerful cards that offer either a Passive benefit or are added to the deck. Be warned though - if the player is defeated, their deck is lost and they have to start all over again. Successfully defeating 8 bosses in one run with all 9 origin classes rewards the Candle King card back.

Monster Hunt
Part of The Witchwood, released April 26, 2018.

Four champions must brave the corrupted and defeat the source of the evil over. Monster Hunt follows a similar formula to the Dungeon Run, but replaces the original classes with four custom classes (The Tracker, The Cannoneer, The Houndmaster, and The Time-Tinker) that have their own hero powers and specially-tailored treasures. Defeating each of the characters' Nemesis unlocks the final fight against Hagatha the Witch, and defeating her rewards the Monster Hunt card back.

Puzzle Lab
Part of The Boomsday Project, released August 21, 2018.

Players are invited to join Boom Labs, helping the scientists complete their projects and eventually stopping Dr. Boom's nebulous evil scheme. This mode offers a completely unique type of gameplay. Rather than fight bosses, players must solve a series of increasingly-difficult puzzles. The Puzzle Lab tests the player's logic, math abilities, as well as their knowledge of how Hearthstone functions as a game. Completing every puzzle rewards the Boomsday! card back.

Rumble Run
Part of Rastakhan's Rumble, released December 13, 2018.

Players take the role of Rikkar, a rookie brawler from the tribe who challenges every single person in the arena to battle. This mode is a return to the Dungeon Run style of Mission, but adds a few twists. Each player and their opponent have a Shrine, which provides a powerful effect and always returns to the field shortly after being destroyed. Completing a run rewards the Rumble Runner card back.

History and design
Missions were first announced in a Year of the Mammoth announcement blog post on the official site, where the Hearthstone team explained that they would be changing the previous Hearthstone release cycle of alternating between Expansion and Adventure releases to instead releasing three Expansions a year, and that "optional single-player missions" would be included in each release to help develop the expansions' lore and narrative. It was also mentioned that the team would be taking their "first step" into this new design with the second expansion of 2017, which was later announced as Knights of the Frozen Throne:


 * ''"Looking back, we learned a lot in 2016 with the introduction of the Year of the Kraken. One of the things we’d like to put additional focus on for the Year of the Mammoth is having additional deck-building options and deck variety in Hearthstone. To help give players additional tools and options to accomplish this, we are changing up the way we handle our release cycle. Previously, a Hearthstone Year alternated between Expansions and Adventures.


 * ''For the Year of the Mammoth, our release cycle will include a ~130 card expansion at the start of the year, a ~130 card expansion in the middle of the year, and another ~130 card expansion at the end of the year.


 * ''Why the change of release cycle?


 * ''At their core, Adventures paint colorful and thematic stories about the Hearthstone universe. Imagine being able to learn about the history and lore behind each of our sets inside the game in a similar way! Defining who the Jade Lotus are through a series of battles between the Mean Streets of Gadgetzan families would have been a great way to supplement the overall Gadgetzan story arc. That concept is something we would like to do more of in future sets: Take the storytelling and cool missions of Adventures, and combine them with the card pools of expansions.


 * ''Cards will be acquired via packs like other expansions in the past; additionally, each release will include optional single-player missions that will help develop the expansions’ thematic narratives and offer fun challenges.


 * We’d like to continue being flexible and refine the way we roll out content so it’s more enjoyable for all of our players. The second expansion of 2017 will be our first step into this new design, and we plan on building on this concept over time. Additional details about our free single player content will come at a later time."

In an Knights of the Frozen Throne interview with Dave Kosak and Jerry Mascho, Kosak elaborated further on the design intent of Missions as opposed to Adventures:


 * ''IGN: How has the shift from missions being linked to adventures – and a smaller set of cards, to being linked to a full expansion set changed your opportunities for storytelling? For instance, when Mean Streets [of Gadgetzan] came out, I was like “man, I’d love to see some more story content around this!
 * Dave Kosak: Right! That’s exactly how we felt about Mean Streets. We had these great great characters, and you kind of had the quest that you could do when the expansion launched to sort of introduce the characters, but you really didn’t get to interact with them in a way that was narrative. And this gives us an opportunity to do that. And yeah, going forward, we’re excited about that. It’ll be full 135 card sets, as well as this opportunity to tell a little bit of story with the missions. And the goal of missions now, it kind of changes, because you’re not gating cards behind the content. Now it’s really about getting people excited about the expansion, getting people interacting with the new cards in a new way, introducing these characters to players, that’s important. It’s especially important here because Hearthstone players might not have played Warcraft 3 or World of Warcraft, they might not know who the Lich King is yet. We’ve got to really establish who the Lich King is and that can be fun, because we kind of give a Hearthstone take on it.

Trivia

 * The player is warned about the difficulty of bosses in the Knights of the Frozen Throne Missions after completing A Fateful Encounter, the Missions' first boss.
 * Descent of Dragons is the first card set to not feature Missions since the game mode was announced. It was instead followed by the Adventure and card set Galakrond's Awakening.
