Nintendo has announced a slate of DLC for Fire Emblem Warriors. The hack-and-slash Switch and New 3DS game will receive three additional content packs following its release, which include new characters and weapons from different Fire Emblem titles.

The game's first DLC pack is scheduled to arrive this December and features content inspired by the series' most recent new installment, Fire Emblem Fates. DLC Pack 2 will follow in February 2018 and includes characters and items taken from Fire Emblem: Shadow Dragon. The final DLC pack arrives a month later, in March 2018, and is themed after Fire Emblem Awakening.
