Armored Core 6 All Hidden Parts And Where To Find Them

12 September 2026 | 236

In Armored Core 6: Fires of Rubicon, expanding your mech's arsenal goes far beyond simply spending credits in the Parts Shop. Throughout the campaign, hidden containers are tucked away in hazardous side routes and intricate industrial structures. Locating these secret chests awards specialized frame components, unique weapons, and high-efficiency inner parts that can alter your combat capabilities.

Finding Early Hidden Chests in Chapter 2 and Chapter 3

Your search for secret gear begins in earnest during Chapter 2's Infiltrate Grid 086 mission. Within this sprawling complex, players can discover the full HC-3000 Wrecker set by exploring side chambers, ventilation pipes, and platforms off the main objective path. Thorough scanning around structural corners helps reveal these well-hidden containers before moving to the next area.

As you progress into Chapter 3, missions like Tunnel Sabotage and Eliminate Honest Brute feature powerful upgrades including the IA-C01W1 Nebula Plasma Rifle and the Double Trouble Chainsaw. Taking time to investigate vertical shafts and platform extensions will ensure you do not skip these rare items.

Uncovering Advanced Upgrades in Chapter 4

Chapter 4 contains some of the most valuable secrets in the game, particularly during the multi-depth Underground Exploration missions. While descending through these massive shafts, players can secure various Ephemera set pieces, including specialized core and head parts concealed near structural struts and caverns. Paying attention to your scanner while navigating complex geometry is essential for spotting these containers.

Later in Chapter 4, the Reach the Coral Convergence mission hides legendary gear such as the IA-C01W3 Aurora Light Wave Cannon and the iconic Moonlight Blade. These items require venturing into outer areas of the submerged city rather than rushing directly toward the main target.

Locating Exclusive New Game Plus Gear

Players aiming for complete completion will need to venture into New Game Plus and New Game Plus Plus playthroughs to unlock final secrets. Advanced missions like Regain Control of the Xylem feature late-game components such as the IB-C03W3 Coral Missile Launcher and the IB-C03W4 Coral Shield. Replaying missions via the Sortie menu allows you to clean up any missed containers while testing out high-tier builds.

Tips for Spotting Hidden Containers

Hidden part containers always feature a distinctive blinking light mechanism on top of their metal frames. Utilizing your AC's head scanner component sweeps the immediate environment, briefly highlighting interactable objects through solid structures. Keeping an eye out for side paths during major boss missions ensures your assembly garage remains fully stocked with every build option.
