You get lost in an ancient egyptian pyramid buried deep under the sand of the desert and full of traps and monstrous beings. Decrypt hieroglyphs to learn spells and to understand the magical nature of artifacts.
Fight your way through dangerous corridors down to the deeper levels of the pyramid in a turn-based fashion. Open sarcophagi or kill enemies and you will find loot. Cast the spells of the dead. Defend yourself with ancient shields. Push your enemies into bottomless pits. Or strike them down with enchanted weapons.
There is no hand-holding of any kind. Figure out the mechanics and rules on your own. Be attentive and creative. Find novel solutions to odd combinations of random events. Be an explorer!
