Locating Filler Metal in NieR: Automata
This guide details the methods for obtaining the rare upgrade material, Filler Metal, in NieR: Automata. Finding it early requires exploration, while later in the game, purchasing it becomes a more viable (though expensive) option.
Farming Filler Metal in the Factory
Filler Metal can be found as a rare drop from randomly spawning items deep within the Factory area. The exact spawn locations are unpredictable, making farming it a time-consuming process with an element of chance. The Factory: Hanger access point provides a convenient starting point for your search after it's unlocked in the main storyline. Note that you may need to unlock this access point again depending on your story progress. While movement speed boosts can help, reliably farming Filler Metal remains challenging. The most efficient approach is to thoroughly explore the Factory, collecting all naturally spawning items.
Purchasing Filler Metal in the Amusement Park
Filler Metal can be purchased from the Shopkeeper Machine in the Amusement Park, but only after completing all three playthroughs and achieving one of the final endings. Accessing the Shopkeeper via Chapter Select after completing the game will unlock its updated inventory, including Filler Metal at a price of 11,250 G per unit. Despite the high cost, this method offers a far more consistent way to acquire Filler Metal than repeated Factory runs, especially considering the necessity of these upgrades for tackling higher-level enemies.
