Cody is an NPC who gives a repeatable instance in Fallout Bay called Gone Nuclear. He complains the Nuclear reactor was taken over by someone masquerading as a health and safety officer and he needs the player to rescue the trapped person.
Codys instance is required for two other quests, Edwards quest Age of Nosferatu and Carmens sidequest. It is reccomended you receive both quests before doing Codys instance but as the instance is repeatable it can be done as often as required.
Codys instance drops bullets, enchanted RYU armor and some food.
