Nintendo has laid out its plans for the post release content for Fire Emblem Fates. The DLC schedule extends from the game's release until April and will include both free and paid content. Downloaded content is accessed through a location called Dragon's Gate, which opens up after Chapter 6.
The first DLC, available with the launch of the game, is a short mission titled "Before Awakening" which will offer a one time reward of either the Hero's or Exalt's Brand. The next two maps, "Boo Camp" and "Beach Brawl", will be the first paid DLC and will be out on February 25, 2016. The following week, on March 3, 2016, sees the release of "Ghostly Gold" and "Musem Melee", two more paid maps.
On March 10, 2016, Fire Emblem Fates: Revelation, the third campaign, is released. Also available after Chapter 6, the additional campaign will cost $19.99 and can be purchased from the game's main menu.
March 17, 2016 will have one paid map — "Royal Royale" — which will have a one time reward that will raise all stats of a character. For March 24, 2016 the DLC will be a two-map set that acts a prequel to the events of the game titled "Hidden Truths I and II". The following week will have the first DLC to feature a map from a previous game, "Vanguard Dawn", which is based on the stage for Elencia's Gambit from Radiant Dawn.
April 7, 2016 will see the release of a map that gives players the opportunity to recruit series staple Anna in "Anna on the Run". The next free DLC, "A Gift From Anna", arrives on April 14, 2016 and will give the option to accept one of two unique items, the Sighting Lens or Witches' Mark. The other DLC for the week, "Ballistician Blitz", is a stage taken from Shadow Dragon and the Blade of Light that has the Sighting Lens as a reward. The final DLC on the schedule, releasing on April 21, 2016 and titled "Witches Trial", uses a stage from Fire Emblem Gaiden and will offer the Witches' Mark as a reward.
Prices for the DLC range from $1.99 to $4.49. All the maps, not including the Revelation campaign, can be purchased at once for a bundled price of $17.99. More details on the DLC can be found here.
