A Fire Emblem mobile app was announced on April 27, 2016 as a part of Nintendo's effort to bring their content to the mobile phone market. Initially announced to release in the fall of 2016, it was later pushed back to an unspecified date within the March 2017 timeframe before its official release date of February 2, 2017 was unveiled.
The game is one of the first titles developed internally by Nintendo for mobile phones. It is not a traditional Fire Emblem experience, but one tailored more toward the mobile market to help drive broader interest in the franchise and the core games on Nintendo platforms. It is also one of the first mobile apps, after the social app Miitomo and Super Mario Run, to make use of the universal Nintendo Account system created in collaboration with Nintendo's corporate partner DeNA.
The game was officially unveiled during a Fire Emblem-themed Nintendo Direct on January 18, 2017. During the Direct, the game's final title Fire Emblem Heroes was revealed, and its story and gameplay were both introduced. It was also revealed that the game is a free-to-play mobile app with microtransactions based on a "gacha" collection structure. All characters that appear in the game will receive new art provided by a variety of artists, as well as new voiced dialogue. Similar to many mobile titles, Fire Emblem Heroes has received and continues to receive updates to add more characters, story chapters, and additional features over time.
Fire Emblem Heroes directly announces new upcoming features to the player base mainly through the in-app notice board. This announces upcoming events such as Tempest Trials, upcoming bonus units for Arena Duel, and announcements for upcoming summoning banners.
The latter is prominently featured on the Nintendo Mobile YouTube page which announces at least three New Hero Banners a month; one comprised of characters in their original forms from past Fire Emblem games, one comprised of seasonal variations of Heroes, and a Legendary Hero banner featuring a powerful Blessed Hero.
Approximately every two months, Heroes also releases a special video series known as Feh Channel, meant to announce upcoming new features and major changes coming to Heroes.
Fire Emblem Heroes also maintains its own Twitter  account.
Game Service in Belgium
Due to legislation passed in the nation of Belgium that defines microtransaction loot boxes in video games as a form of gambling, as well as the therefore unclear legal status of gacha collection titles, Nintendo ended service for Fire Emblem Heroes in Belgium on August 27, 2019. On the same day, Nintendo also ended Belgian service for Animal Crossing: Pocket Camp, which features loot boxes. This comes on the heels of other companies either pulling their titles from Belgian service or disabling the ability to buy loot boxes in the Belgian versions of games that otherwise remain in operation.
The game follows two protagonists, the royal siblings of the Kingdom of Askr, Prince Alfonse and Princess Sharena, as well as gathered heroes from other worlds. Together, they plan to fight against the opposing Emblian Empire and their leader, Princess Veronica.
The war between Askr and Embla shifts with the introduction of the antagonistic nation of Múspell ruled by the evil King Surtr, which threatens to engulf the world in fire. They are opposed by Princess Fjorm of the kingdom of Nifl, who allies herself with the Askr royals.
Not long after the war against Múspell, Hel, the ruler of the Realm of the Dead, has invaded Askr with her army of the dead. Those who confront her will witness their demise. Princess Eir, Hel's daughter, was forced by her mother to ally herself with the Askr royals to backstab them, but ends up betraying her mother and staying with them in the end.
Immediately after defeating Hel and her forces, Askr's queen Henriette hears a report about a village in Askr in an endless sleep. The Askr royals rush to investigate where they find themselves in Ljósálfheimr, the realm of dreams. The royals ally themselves with Peony against the nightmare realm of Dökkálfheimr.
Sometime after leaving Dökkálfheimr, Askr is attacked by soldiers from Niðavellir lead by Reginn who plan to conquer the other realms. However after they defeat her, Reginn defects to the Askr Royals telling them that she wants the conquests to stop even if it means confronting her brothers Fáfnir and Ótr who want to capture Kiran for mysterious reasons.
Fire Emblem Heroes is a strategy game requiring a mixture of tactics and unit training.
Units and Team Building
- See also: Hero (Heroes)
Heroes revolves around using various Fire Emblem characters from throughout the franchise, mainly focused on characters from all of the main series titles and Tokyo Mirage Sessions ♯FE. Several characters debut in Heroes tied to its independent story including the three Heroes main characters Alfonse, Sharena, and an Askran Anna.
Players can freely create teams of up to four Heroes for most game modes, though there are exceptions for certain modes like Rival Domains and Aether Raids. These Heroes can be assembled from a roster that players continuously grow by Summoning or acquring from Quests and certain game modes, thus allowing millions of combinations of teams of player's favorite characters from the franchise.
Much like the core franchise, players also spend time fostering the growth of their Heroes, helping them to gain stats and acquire/learn skills to clear many PvE content that the game hosts as well as various PvP options to test their units against fellow Heroes players. Each unit is a unique part of the player's roster and players can obtain and utilize multiple copies of the same character. While some characters could wield multiple weapon types in their game of origin, all characters summoned are hard locked to a particular weapon.
Battles and Combat
Players can engage in various PvE and PvP modes using their characters, sometimes requiring Stamina or other resources to play. A vast majority of battles consist of the player challenging a pre-determined enemy team for story modes and certain challenge maps, randomized enemies such as in the Training Tower, and defensive teams created by fellow Heroes players in most PvP modes.
Battles retain the series Turn-Based Grid Tactical RPG style utilized throughout the franchise with players sending their Heroes to clash with enemy teams.
Combat retains many of the main series features including stats that determine character performance in battle or movement. Some features in the franchise do not appear in Heroes such as Luck and Skill stats, Critical Hits, and stat growths. Some features that do make an apperance in Heroes, albeit slightly tweaked, include In-Combat and Out-Of-Combat Skills, the Weapon Triangle, and Supports. While the series is known for its Classic Mode, Heroes utilizes a Casual Mode style, thus fallen units do not permanently vanish from the player's roster.
Due to the sheer number of units available in Heroes and the various weapons and skills available for Skill Inheritance, players can create vastly different and unique builds to tailor make their armies to suit their needs or desires, thus creating bold and unique possibilites for players to challenge themselves and other players.
- Story Mode – Players play through the story of Heroes, following the adventures of Prince Alfonse and Princess Sharena as they battle the Embla empire lead by Princess Veronica. There are thirteen playable chapters in Book 1, each containing 5 battles each. Players encounter a series of Fire Emblem characters from different Fire Emblem games, though each chapter focuses on a specific game. Each map costs a varying amount of stamina, harder battles cost more stamina. Completing each individual battle rewards the player with an Orb upon its first completion. Completing a chapter unlocks the ability to battle the map on Hard and Lunatic with raised Stamina cost and enemy levels. In addition to the main story, there are also Paralogue stories that release over time that are set outside the main narrative. Xenologues, which exist in the Paralogue section, are brief chapters set in-between chapters in the main story.
- As of Version 2.0, a new story called Book II has been added. In Book II, the players play through a new adventure, where they will help Princess Fjorm of the Ice Kingdom of Nifl battle against the Flame Kingdom of Múspell ruled by King Surtr.
- As of Version 3.0, a new story called Book III has been added. In Book III, the Order of Heroes faces a new threat: The army of the dead led by Hel, the ruler of the Land of the Dead. Eir, the Princess of Death and Hel's daughter, joins the Order of Heroes.
- As of Version 4.0, a new story called Book IV has been added. In Book IV, the player find themselves in the Realm of Dreams, ruled by Freyr, where nightmares are invading from the Realm of Nightmares, lead by Freyja. Peony a ljósálfar from the Realm of Dreams, joins the Order of Heroes.
- As of Version 5.0, a new story called Book V had been added. In Book V, Askr faces invasion from the realm of Niðavellir at the order of its king, Fáfnir. A princess of Niðavellir, Reginn, leads one of the first invasions, but she defects and joins the Order of Heroes.
- Tactics Drills - As of Version 2.7, a new mode, Tactics Drills, has been added in the Story Maps. It is designed to test the player's strategy and they must overcome the challenges with a turn limit.
- Heroic Ordeals - Heroic Ordeals feature a map designed for each Hero in the game, in which that hero and one other must rout the enemy.
- Multi-Map Battles - Multi-Map battles are battles in which players must survive multiple maps in a row.
- Chain Challenge was added in Version 1.5 in the Story Maps section, before later being moved to Multi-Map Battles. In Chain Challenge, players can play through the past chapters from the main story, only this time they can play all 5 battles from an entire chapter, and all 10 battles from both chapters. Like the Tempest Trials, characters that fall during the challenge are lost and cannot be utilized for the rest of the challenge run.
- Squad Assault was added in Version 1.5 in the Story Maps section, before later being moved to Multi-Map Battles. In this mode, players will have to prepare 20 units to clear a series of maps. Once a player clears a map with one team, that team from the last battle cannot be utilized for the rest of this challenge, forcing the players to use another team before the next battle, no duplicates. Unlike the Chain Challenge, if one single character from the player's team falls during this challenge, the game is over
- Blessed Gardens is a game mode where players battle against the enemies from each of the previous paralogue maps. However, only the Legendary Heroes and Heroes with Blessings are allowed in this mode. Furthermore, the players must clear the maps without losing a single unit, much like Grand Hero Battles. Players can earn rewards upon clearing the maps, such as Orbs, Hero Feathers, Divine Dew, and the four elements of Blessings. This mode was moved into the Multi-Map battles section and stopped seeing new additions with the introduction of Aether Raids, which took its spot on the world map.
- Training Tower– A tower with eleven strata of increasingly strong enemies that awards more EXP than regular maps. Each stratum starts with 5 Normal difficulty levels, 3 Hard levels, and 3 Lunatic levels. The stamina required to complete each stratum increases as the difficulty rises as well. This is also where players can obtain Shards and Crystals for EXP that can be distributed and Badges and Great Badges that are used to promote characters to higher Star ratings. Players may also use the tower to train characters to level 40 and gain more skill points.
- Special Maps – Consisting of a variety of maps, Special Maps are defined typically as maps that appear for a limited time. Some of the more notable and consistent category of Special Maps are as follows:
- Daily Hero Battle - In this series of battles which cycle daily, players challenge a special team lead by a specific Fire Emblem character, without losing a single unit on their team. Upon completion for the first time, the player recruits the lead into their army. The tier of the recruited Hero depends on the difficulty of their map.
- Grand Hero Battle - Similar to the Daily Hero Battle, players challenge a special team lead by a specific Fire Emblem character, without losing a single unit on their team. Upon completion for the first time, the player recruits the lead into their army. The tier of the recruited Hero depends on the difficulty of their map. The earliest GHB maps cycle daily, but the schedule for when GHBs outside of those two rotations return is unclear.
- Bound Hero Battle - Usually accompanied by a summoning banner, Bound Hero Battles are challenging maps where players face a challenging map based around a pair of Heroes without losing a single unit on their team.
- Legendary and Mythic Hero Battles - Accompanying the appearance of a Legendary or Mythic unit on the monthly Legendary or Mythic summoning banner (with the exception of Fjorm, Gunnthrá, Eir, and Peony), a Legendary or Mythic Hero Battle is a challenging map with reinforcements that players have to clear without losing a single unit on their team. The highest difficulty rewards a golden version of an accessory.
- Special Training - Reminiscent of the Fire Emblem: Warriors maps, Special Training maps are intended to help players train their Heroes, a melee, magic, bow, and all out assault based training map cycle daily. All the enemies on these maps are easy to defeat.
- Rival Domains - Introduced in Version 2.9, in this mode, players assemble a brigade of 20 heroes to take on a much bigger map than usual. Players must seize the enemy bases while protecting their own with their team of 20, which deploys all 20 in order than cycles back to the beginning.
- Relay Defense - Introduced in Version 2.9, Relay Defense is a now defunct mode, as it was discontinued in Version 2.11, after two runs. In this mode, players defended their bases for 8 turns using a brigade. Five units were deployed at a time, and were switched out for the next five every two turns.
- Arena Duels – Players challenge teams created by other Heroes players for points. Players attempt to battle 5 consecutive teams for a cumulative score which are compared to other players each week. Ending week rank can move players up or down tiers with the highest tiers comprised of players with near perfect teams.
- Arena Assault - A gauntlet of Arena style battles. Players challenge 7 Arena Defense teams in a row. However, player's must create 7 different teams, one for each battle.
- Allegiance Battle - A biweekly event, players challenge a map based on a Legendary Hero, and try to defeat every opponent and reinforcement on the map. Defeating an opponent the player is strong against (ie: green against blue) grants a greater score, and losing anyone lowers the score. The higher the score, the greater the rewards.
- Resonant Battle - In this mode, players attempt to defeat as many thieves as possible before they escape.
- Events - Events are non-permanent game modes. There are three types of Events and each reward players in different way for participating in it.
- Voting Gauntlet - Every so often, eight Fire Emblem characters are selected to participate in a tournament based on popularity. Players select a unit to represent one of the eight character and they participate in battles to earn points for their candidate. The end results of the Gauntlet awards players with Feathers based on the represented unit's performance and final scores each round. Players earn bonus points based on if they utilize the hero they choose to represent. For example, players who represent Lucina earn bonus points for using her in a Voting Gauntlet battle. However, this unit must be the player's own, as they will not get bonus points if they use a Lucina from another player. Additionally, the unit must match the variant of the unit participating in the event. For example, if Alfonse: Prince of Askr is participating in a Voting Gauntlet, then using Alfonse: Spring Prince will not apply a bonus.
- Tempest Trials+ - Like the Voting Gauntlet, Tempest Trials are a periodic event. Players battle against a gauntlet of enemy teams of various difficulties. Characters that fall during the gauntlet are lost and cannot be utilized for the rest of the gauntlet run, but is not permanently removed from the player's roster. Once a player has cleared a gauntlet, they are graded based on the difficulty of the set, the number of units lost, and the number of cumulative turns to clear the map. Players can earn bonus rewards for reaching certain point totals through the event including feathers, orbs, extra skills, and exclusive Heroes. After a few Tempest Trials Minis, with lowered score thresholds to obtain every reward, Tempest Trials kept the score thresholds from the Minis, and were permanently rebranded to Tempest Trials+ with the Thunder's Fist Tempest Trials+.
- Tap Battle: Illusory Dungeon - Tap Battle: Illusory Dungeon is a periodic event, like the Voting Gauntlet and the Tempest Trials. In this rhythm game, players battle against the enemies by simply tapping the screen. If the timing is just right, enemies will be hit by a critical attack and fly off-screen. In order to achieve an S rank for a perfect run, the players must rack up the combos by landing multiple critical attacks in a row. In Casual mode, the players can tap the bottom screen with the Summoner and Feh. In Expert mode, they can tap the spaces next to their 4 units in the right order.
- Grand Conquests - Grand Conquests is a periodic event. Three armies battle to conquer territory across a continent. Each Grand Conquests event last for 3 battles, with each battle taking course over two days. Like the Rival Domains Special Maps, players will battle with the help of their friends against the enemy armies to control the camps and forts. When the battle ends, the armies will earn the rewards, based on how many areas they controlled.
- Forging Bonds - Forging Bonds is a periodic event that coincides with the release of brand new units. Players challenge maps in order to increase their bond with one of four highlighted characters. Rewards are given at certain milestones, most notably unique accessories of that character and special support conversations.
- Røkkr Sieges - Røkkr Sieges is a periodic event in which players face off against Røkkrs, which are giant shadowy versions of Heroes created by Loki. The goal is to deal as much damage as possible within 7 turns. This damage is then combined with the damage of other players for a total amount of damage to the Røkkr. Rewards are given at milestones based on total damage dealt.
- Lost Lore - Lost Lore is also a periodic event where players send out their heroes on scouting missions to recover lost pages from the books about their worlds. When heroes return, they bring rewards for the player.
- Hall of Forms - In the periodical Hall of Forms event, players use and train preset Forma units created by Thorr and clear various maps reminiscent of the Training Tower with these units.
- Mjölnir's Strike - Mjölnir's Strike is a periodic event with three phases. In the first phase, players build a defense by using various structures and selecting a team. In the second phase, the player has 7 turns where they defend their base from an invading army led by a Grand Hero Battle unit and Thorr. In the final phase, every player works together to fire arrows back at the invading army commanders and try to outscore the opponent in damage.
- Pawns of Loki - Pawns of Loki is a periodic event similar to games like Auto Chess. In this mode, the player advances through nine rounds of battle against randomized slates of opponents. Each round begins with the player drafting characters to place on the board, with duplicates allowed. If three of the same character are placed, they merge to become a higher level, more powerful version of that character. As in Auto Chess, the actual combat is automated. A round is won if the total remaining HP on the player's side is greater than the remaining total of the opponent.
- Frontline Phalanx - Frontline Phalanx is a periodical event in which players choose to support one of four characters facing down a strong enemy army. Over-supporting a character raises the risk of them losing, but backing a character with more support also grants greater rewards.
- Aether Raids - Aether Raids is a game mode where players create defensive maps utilizing special structures and units from their roster. Players then battle against other player's maps in order to gain Lift for their Aether Base, granting greater rewards to improve their maps and Heroic Grails to summon Grand Hero Battle and Tempest Trial units.
- Aether Resort - Similar to the defense building aspect of Aether Raids, in the Aether Resort, players can place various facilities, such as a concert hall, bathhouse, and garden, for their heroes to visit.
Fire Emblem Heroes includes a large roster of characters from across the full history of the franchise, along with some original characters. There are currently 705 unique playable units with 433 of the franchise's cast represented in at least one form.

In addition to the standard characters on the roster, there are also special variants of select characters that have been released as part of timed seasonal and special events. These character variants have appearances, skills, and weapons that differ from their standard forms.

- The tutorial gives the player various units during and after the preface, which is part of the tutorial along with the prologue. When the game launched, you were given a two-star Virion in the second part of the preface. With the version 2.5.0 update, however, this was changed to a four-star Takumi, with Virion now being given after completing the preface. That same update also increased the base star rating of all units obtained from the tutorial from two stars to four stars.
- Players who started playing before this update were given the four-star Takumi and materials to increase the tutorial units to four stars via a log-in bonus.
- As of February 12, 2019, Fire Emblem Heroes had earned a worldwide revenue of US$500 million. It is the first mobile title published by Nintendo to cross the $100 million threshold and currently stands as the company's most profitable mobile title to date.
- Fire Emblem Heroes was initially rated E10+ by the ESRB, but it was later raised to T, most likely due to "partial nudity" and profanity.
- In April 2019, a crossover event with this game ran in Dragalia Lost, where four characters from this game were made obtainable. One of the characters was Alfonse, who was a Light-attuned sword adventurer obtained for free, but he would only join you permanently if you maxed out his friendship. The other three characters were obtainable through a summon showcase, being Marth, a Flame-attuned sword adventurer, Fjorm, a Water-attuned lance adventurer, and Veronica, a Shadow-attuned wand adventurer. In April 2020, the event was revived, followed shortly by follow-up of the event where another four characters were made obtainable. Sharena, who was a Light-attuned lance adventurer who would immediately join your army upon activation of the event. The other three were Peony, a Light-attuned wand adventurer, Chrom, a Flame-attuned sword adventurer and the Shadow Dragon version of Tiki, a Water-attuned dagger adventurer.
- Though Veronica is classified as a wand adventurer, she actually uses a tome, which overwrites the appearance of whatever weapon she is equipped with.
- The same also applies to Peony, whose weapon is overwritten with Flower of Joy, and Tiki, whose weapon is overwritten with Breath of Fog.
- Out of these four characters, Veronica is the only character whose Dragalia Lost artwork depicts them using a different weapon than their default weapon in Fire Emblem Heroes, as she shown with Gespenst instead of Élivágar.
- Though Tiki is classified as a dagger unit, she has never been classified as a dagger user before in the game, not even in her previous appearances, this is most likely because her dragon form has to be activated like the other dragons.
- Alfonse's sword, Fólkvangr, was obtainable as a five star Light-attributed event weapon. However, its description states that it is a replica, implying it is not the real Fólkvangr.
- Though Veronica is classified as a wand adventurer, she actually uses a tome, which overwrites the appearance of whatever weapon she is equipped with.
- Prior to Book V, the main antagonist of each Book has been a Green unit.
- Unlike other CG movies in Fire Emblem Heroes, the ending to Book IV was uploaded separately to YouTube and is not in the game itself. Choosing to view the movie from within the game opens a link to YouTube on the player's phone.
