The Realm of Sun is a magical world situated above the Kingdom of Daventry. Powerful beings known as Archons dwell there, guarding the Mask of Eternity, which preserves balance in the world. But on an ominous day, Lucreto, the leader of the Archons, turns evil and shatters the Mask into pieces. One of such pieces falls down, right under the feet of a simple peasant and fighter named Connor. As he picks up the fragment, he finds out that all the inhabitants of the land have been turned into stone. He must now search for the other pieces of the Mask, repair it, and face Lucreto in the Realm of Sun.
King’s Quest: Mask of Eternity is the eighth installment in the King’s Quest series, and the first one done completely in 3D. Gameplay-wise, it differs from its predecessors by introducing considerable action and role-playing elements. It doesn’t entirely depart from its adventure roots, however, featuring commands for looking, talking to people, picking up objects, and using them to solve inventory-based puzzles.
Connor may encounter hostile creatures and can fight them using his melee weapons or bow. Some portions of the game also include environmental hazards the protagonist has to avoid, or jumping puzzles reminiscent of platform games. RPG elements are present in character development: Connor gains experience points from vanquishing enemies and completing tasks, and eventually levels up, increasing his hit points and combat parameters. Weapons and armor can be found or bought for money obtained from defeated foes.
