Sea of Darkness is the 32nd installment in the Nancy Drew point-and-click adventure game series by Her Interactive. Players take on the first-person view of fictional amateur sleuth Nancy Drew and must solve the mystery through interrogation of suspects, solving puzzles, and discovering clues. There are two levels of gameplay, Amateur and Master sleuth modes, each offering a different difficulty level of puzzles and hints; however, neither of these changes affect the plot of the game. It is the last game to feature Lani Minella as the voice of Nancy Drew, and is also the last game to use Her Interactive's proprietary game engine. The next game, Midnight in Salem, uses Unity. ESRB rates the game 10+ for mild alcohol reference and violent blood.
