Peret em Heru: For the Prisoners is a Survival Horror RPG set in Egypt in 1998, the same year it was released. The story follows Ayuto Asaki, a recent high school graduate who's visiting Egypt with three of his friends when their tour group crosses paths with Professor Tetsuya Tsuchida and his assistant, Dr. Koji Kuroe. The archaeologist has just made an incredible discovery — hidden beneath the Great Pyramid of Giza is a sprawling underground ruin, and he offers their tour group the chance of a lifetime, to explore the depths alongside them.
