Dragalia Lost is an action role-playing game for mobile devices. It is the first original mobile game by Nintendo and the first in their partnership with Cygames. It came out on September 27 in North America and certain parts of Asia.
The main gameplay is divided into missions. In a party of 4, the player defeats monsters in a dungeon and then faces a boss monster at the end of the dungeon. Dungeons also have traps that can hurt the party. The player moves by dragging their finger on the screen in the direction the player wants to move. The player can attack by tapping the screen. To dodge attacks (indicated by a red shape on the ground, the player swipes in the direction they want to dodge. To switch characters, the player touches the character portrait. Each character has a special move which the player can activate by tapping the icon next to the character portrait. With enough special energy, the player can transform the active character into a dragon and deal massive amounts of damage. All missions can be played in co-op in which the AI companions are played by real people
The bosses are much stronger than the average enemy with several times the health. They also do much more varied attacks. Similar to Granblue Fantasy, the bosses have a mode bar which fills with damage taken. It will first go into Overdrive which means the boss will deal more damage but, when the bar is filled again, the boss will be stunned in Break which allows the player to wail on it with combos.
Each character has a weapon type (that determines their combat style) and an element. They can also equip a Wyrmsprint and be bonded to dragon the player has. The enemies also have elements which have weaknesses and resistances.
Dragalia Lost is the result of a partnership between Nintendo and Cygames. It also marked Nintendo buying 5% of Cygames' stock. The game was first revealed to the public via a trailer following Nintendo's April 2018 investor meeting. Soon after, an official twitter was launched teasing details about the characters in between the game's announcement and launch.
The game had a Nintendo Direct detailing the game's systems on August 29, 2018.
