Fate/Grand Order is a free-to-play mobile RPG developed by Lasengle (originally Delightworks) and published by Aniplex. Set in the TYPE-MOON Fate universe, players take on the role of a Master tasked with traveling through time to fix corrupted "Singularities" that threaten human history and prevent the extinction of humanity.\n\nGameplay centers on turn-based command card battles where players assemble a party of Servants — legendary historical, mythological, and literary figures summoned as powerful warriors — and equip Craft Essence cards to boost their abilities. The gacha system is used to summon new Servants and Craft Essences, with rarity tiers ranging from 1★ to 5★.\n\nThe game is story-heavy, featuring fully voiced main story chapters (Chapters/Lostbelts) written by prominent visual novel authors, along with seasonal limited events and character-specific interludes. It has amassed a massive global fanbase and surpassed $7 billion in lifetime revenue, making it one of the highest-grossing mobile games of all time.
