Final Fantasy Brave Exvius was a free-to-play role-playing video game developed by Alim and published by Square Enix for iOS, Android and Amazon Fire devices. Served as the spin-off of the Final Fantasy series, the game was the first collaborative effort between Square-Enix and Alim. Since August 2019, the app had been downloaded over 40 million times worldwide. Another tactical RPG spin-off video game, titled War of the Visions: Final Fantasy Brave Exvius, was released in Japan on November 14, 2019, and globally on March 25, 2020.

It was discontinued outside of Japan on October 30, 2024, and in Japan on October 31, 2025.

Brave Exvius was designed as a turn-based role-playing game, combining elements from the Final Fantasy series with those of previous Alim game, Brave Frontier. Similar to Brave Frontier, the battle system consists of a simplified interface where players can command their characters to attack by touching the character's corresponding attack button, and special attacks or items can be used by swiping the button and choosing the desired command. The game also used elements from the Final Fantasy franchise, such as magic spells, character-specific limit breaks, and the summoning of creatures (known as 'Espers').

Characters were presented in a pixel art style. As part of the game's gacha system, players summoned characters from past Final Fantasy and Brave Frontier titles. The rarity of summoning has ranged from 1 to 5 stars, with five-star summons (only inside the base) to be upgraded between 6 and 7 stars. Players then used those characters to build custom parties of the five units. They also recruited an additional 6th unit from other players. Through collaboration events, players had also been able to summon characters from other Square Enix titles such as Tomb Raider, Kingdom Hearts and Secret of Mana as well as multiple forms of Ariana Grande and Katy Perry. Players advanced through a series of stages until they encountered and defeated the final boss, during which they gained experience points, crafting materials and money.

The game also featured 'exploration' stages (a new addition compared to Brave Frontier), during which players were able to freely explore towns and other areas in a classic RPG style via touch controls, interacting with characters, visiting shops, obtaining quests, looking for resources and fighting enemies in random encounters (during which, the interface remained the same as regular battle stages). Hidden objects from exploration areas was the character known as the 'Fat Chocobo', who sold rare, exclusive items in exchange for a specific resource, known as 'Star Quartz'.

An arena mode was also available; allowed players to compete against the teams of other players. The game also featured various limited-time story events, where-by new stages and exploration areas are available for a limited duration.

Energy was a resource which players required to begin most stages. It re-charged themselves from real-time, even when the game was closed, or in the context of ‘sleep-mode’. New players began the game with a maximum energy level of 10, but gained more capacity as they completed stages and increase their 'player rank'.

The main way to access the story and lore of Brave Exvius is via the world map. In the world map, there are multiple continents, which correspond with the game's story arcs. To play, or continue with the story, the player must complete each continent to unlock a new continent. New continents are added to the game with periodic releases, as the story is expanded.
