Fester's Quest — About this game
Fester’s Quest (North American release) is an NES action-adventure based on The Addams Family. Uncle Fester explores an overhead town and sewer network, enters side-view houses for supplies, and tackles first-person corridor sections before six major bosses. Blue items improve the gun or whip, while red items reduce weapon power, so identifying drops before collecting them is important. Keys, light bulbs, potions, food, allies, and clue pieces support a longer quest in which progress depends on learning the interconnected routes as well as surviving combat.
