Ys: The Oath in Felghana

When redheaded thrill-seeker Adol Christin and his eternal blue-haired companion Dogi make an unannounced visit to Dogi's homeland of Felghana after an eight-year absence, it quickly becomes apparent that things have changed dramatically. Hordes of violent monsters roam the outskirts of town, a long-dormant volcano has suddenly sprung back to life and the new lord of the land has begun mercilessly and inexplicably extorting money from its long-suffering citizens. While Dogi seeks out his former combat master for answers, Adol tends to the townsfolk -- and finds himself embroiled in a world of political conspiracies, ancient legacies and unthinkable taboos. A complete 3D reimagining of the 16-bit console classic "Ys III: Wanderers From Ys," Ys: The Oath in Felghana is a fast-paced action role-playing game with tight controls, Metroidvania-style exploration elements, intense combat with epic screen-filling boss battles, and a thrashing, percussive arranged soundtrack that's been heralded by many as one of the best of all time. Based on the original 2005 PC release, this classic is finally officially available in English. Come see why Falcom fans the world over regard this game as "Ys, Perfected"! Six difficulty levels ranging from "Very Easy" for casual players to "Inferno" for true old-school gaming masters. Unlockable "Time Attack" and "Boss Rush" modes for anyone looking to show off his/her boss-taming abilities. Adjustable high-resolution PC graphics with original blood effects intact. Gamepad support in addition to standard keyboard and mouse controls.
