Are you still playing Fire Emblem Heroes? Cool, so am I. Apologies if you've tried to friend me recently; my queue is filled. Yay! I'm popular!
Nintendo's doing its best to keep our interest by regularly updating the free-to-play strategy mobile game with new content. The latest dish on the menu is the Family Bonds summoning event, which replaces the launch summoning events.
If your luck is good, you might conjure up the new arrivals: Ephraim and Eirika from Fire Emblem: The Sacred Stones, or Seliph and Julia from Fire Emblem: Genealogy of the Holy War.
Genealogy of the Holy War was released for the Super Famicom in 1996 and never made an official appearance outside of Japan (though a fan translation exists). There's a good chance we'll get a remake someday, given the upcoming remake for Fire Emblem Gaiden (as Fire Emblem Heroes for the Nintendo 3DS).
There's also a new story to play through in Heroes titled "Family Bonds." The new narrative puts you up against the game's recent arrivals. You get Orbs and Crystals for clearing the new missions, so if you've drained your Orb-earning story quests dry, here's a good chance to replenish your bank. All the better for summoning devastating brother and sister teams, my dear.
So that's the new Fire Emblem Heroes update in a nutshell. No word on whether Nintendo fixed the glitch that gives characters Satan's own voice.
