Armored Core 6 Secret Parts: Hidden Parts and Locations

Unlocking the full potential of your mech in Armored Core 6 Fires of Rubicon requires more than just buying components from the in-game shop. Scattered across various missions are hidden gear containers that store high-performance weapons, frame components, and specialized inner parts. Locating these secret items allows players to build versatile mechs capable of tackling the game's toughest challenges.
Early Game Hidden Containers in Chapter 2
The hunt for secret parts begins in earnest during Chapter 2, specifically in the Infiltrate Grid 086 mission. Players exploring this massive industrial facility can discover the full HC-3000 Wrecker set, which includes head, core, arms, and leg components. Checking hidden alcoves, drop-down shafts, and areas behind smelting streams will reward thorough mercenaries with these durable armor pieces.
Mid-Game Discoveries Across Chapter 3
As you progress into Chapter 3, missions feature powerful weaponry concealed in dangerous side paths. In Tunnel Sabotage, players can venture deep into side caverns to locate a container holding the IA-C01W1 NEBULA plasma rifle. Later missions like Eliminate Honest Brute hide utility components like the BC-0600 12345 booster alongside devastating weapons like the Bad Cook flamethrower and Double Trouble chainsaw.
Late Game High-Tech Gear in Chapter 4
Chapter 4 contains some of the most sought-after equipment in the game, including components from the elusive Ephemera series. Deep underground missions such as Underground Exploration Depth 2 and Depth 3 house hidden FCS units, boosters, and core parts inside off-path chambers. Players who explore the outskirts of the Reach the Coral Convergence arena can also claim iconic armaments like the Moonlight Blade.
Tips for Finding Hidden Chests
To ensure you do not miss any valuable gear containers, utilizing your mech's scanner tool is essential during exploration missions. Equipping a head unit with a high scan distance attribute makes detecting hidden chests through walls much easier. Replaying completed missions from the sorting menu gives pilots the freedom to search every corner without worrying about initial mission pressure.
