In Demon Stone, the player directs a party of three characters ? Fighter, Sorcerer and Rogue. The player controls one party member at a time -- switching between them on the fly -- while the other party members are controlled by the engine?s sophisticated artificial intelligence. For example, when the player controls the Fighter, the Sorcerer and Rogue will continue to engage in combat, cast spells and assist the player in defeating all challengers. In many situations, the characters will be able to divide and conquer difficult objectives ? while the Fighter holds back a horde of Yuan-Ti snakemen with brute force, the Sorcerer supports him with devastating ranged magic while the rogue sneaks above and behind them for a coup de grace. The player participates seamlessly in each critical moment as they are cinematically switched from one perspective to another.
