Fate/Extra is an RPG with a unique battle system. The game takes place in a futuristic school where 128 people are competing in a deadly battle royale for the Holy Grail, which grants wishes. The main character has lost their memories and must navigate this new world to uncover their past and their purpose. As they progress through the story, they can interact with other characters, gather information, and make choices that affect the outcome of the game.
The gameplay is divided into two main sections: exploration and combat. During the exploration phase, players can move around the school, talk to other contestants, and learn more about their motivations and goals. This is presented in a visual novel style, with branching dialogue paths that allow players to make choices that impact the story. Once the player has gathered enough information, they can enter the dungeon crawling section, where they must use a rock-paper-scissors combat system to defeat enemies.
