An overhaul of Fire Emblem: The Binding Blade, Project Ember looks to tweak and alter various mechanics of Fire Emblem 6 to create a unique and different experience from the original title. Ranging from unit rebalancing from their bases to growths, to giving various units preferred weapons, altering the promotion of the main protagonist Roy, adjusting how archers work, altering the story in slight ways, as well as altering various details in the maps. Project Ember furthermore adds a new Maniac difficulty to push the various mechanical changes the game enforces to their limits.
