Fire Emblem: Fortune's Weave on Switch 2 features a single save file system designed to track multiple story paths simultaneously. Intelligent Systems chose this approach to prevent progress loss and avoid system complications, though they added creative features like chapter checkpoints for each protagonist to allow replaying and reviewing content.
Fire Emblem: Fortune's Weave was originally conceived with eight protagonists but was scaled back to four main characters plus Eshmel, a fifth protagonist who serves as the player's initial character. The developers chose this structure to unify the multiple story perspectives into a cohesive narrative, and the game introduces firearms to the series for story-specific reasons.
