In a near-future society where personal memories can be bought, sold, and even stolen, you play as Echo, a 'Memory Broker' who navigates a treacherous underground marketplace. You must gather fragments of your own past while dealing with rival brokers and mercenaries who seek to either ally with you or erase your very existence. Each choice you make influences the memories you collect, leading to multiple endings as you attempt to recover your stolen past before your memories become a form of currency lost forever.
