In the expansive universe of Call of Duty , a codex serves as an in-game library or database. As players progress through campaigns and multiplayer seasons—such as the recent expansions in Black Ops 7 —they often uncover encrypted intel, classified documents, and hidden lore. The codex organizes these fragments, giving players a comprehensive view of the overarching storyline, character motivations, and world-building details that might be missed during fast-paced action sequences.
