Armored Core 6: All Hidden Parts [Stats, Descriptions, & Locations]

Learn about all the locations from where you can get the hidden parts in Armored Core 6, ranging from weapons to complete armor sets.

The Armored Core 6 hidden parts are an excellent way to fill your inventory with meaningful and effective mech parts without using any COAM. These units generally require you to stray from the mission objectives and focus on exploring areas to find some hidden chests. Inside these chests, you’ll find different weapons as well as Frame and Inner Components for your mech, which you can customize to craft a new build and further dominate the battlefield with your preferred playstyle.

Key Takeaways
  • Players can discover the Armored Core 6 hidden parts, which can be found in chests scattered across different missions and do not cost any COAM currency.
  • Once the secret parts are obtained, players must complete the whole mission for those parts to enter their inventory.
  • There are 19 in-game hidden parts, most of which are hidden in Chapters 2, 3, and 4 of Armored Core 6, mainly ranging from weapons to armor sets, with some additional components like boosters.
  • The final two secret parts are in the “Regain Control of the Xylem” mission, which is only accessible in NG++.
  • Besides their stats, one of their significant benefits is that players can reserve their COAM for superior but much more expensive AC parts.

Infiltrate Grid 086

Your first list of Armored Core 6 hidden parts, the WRECKER collection, is obtainable in Chapter 2’s first story mission after beating Balteus. As you’ll see, this armor set is incredibly versatile, favoring several different builds and playstyles.

HC-3000 WRECKER

AP 1130
Anti-Kinetic Defense 200
Anti-Energy Defense 170
Anti-Explosive Defense 187
Attitude Stability 322
System Recovery 55
Scan Distance 270
Scan Effect Duration 3.0

The HC-3000 is a promising head component to the WRECKER set on the list, given that it’s arguably one of the more favorable hidden early parts in Armored Core 6. It comes equipped with the best Anti-Kinetic and second-best Anti-Explosive Defense, a noticeable AP increment, and decent Attitude Stability. However, it lags in Scan abilities, making it a discouraging choice for players to constantly use their Scan to learn about enemy positionings.

Upon entering Chapter 2, you can follow these steps to obtain one of the first WRECKER parts in Armored Core 6:

  1. From the mission’s starting point, proceed towards your first objective marker beyond the two bridges, where you’ll fight “Invincible” Rummy.

  1. After taking down Rummy, continue following your objectives until you access a door and reach the vents beyond it.
  2. At the end of the uppermost level, drop down to take out the enemy MT and head to the back of the room opposite the exit to find the chest with the HC-3000 inside.

CC-3000 WRECKER

Anti-Energy Defense 434
Anti-Explosive Defense 461
Attitude Stability 532
Booster Efficiency Adj 80
Generator Output 96
Generator Supply 100

Like the HC-3000, the CC-3000 is one of the defense-focused WRECKER parts with impressive AP and Anti-Kinetic, Anti-Explosive, and Anti-Energy Defense stats in Armored Core 6. However, this Core part gets outshined by another Core piece, the DF-BD-08, which excels in almost every category while only being heavier by 1000 units. But since every hidden part is free, you can reserve your COAM to get the DF-BD-08 later on and use the CC-3000 in the meantime.

Here’s how to get the WRECKER’s Core component immediately after obtaining the HC-3000, as mentioned earlier:

  1. As you follow through the vents, you’ll reach a room with several hostile MTs, which you can avoid entirely and sprint to the area behind the molten lava chamber on your right.

  1. Drop down to the ground floor here, and you’ll spot the CC-3000’s crate.

AC-3000 WRECKER

Anti-Kinetic Defense 232
Anti-Energy Defense 170
Anti-Explosive Defense 237
Arms Load Limit 15800
Recoil Control 232
Firearm Specialization 26
Melee Specialization 13

Out of all the arm parts in AC6, the AC-3000 WRECKER stands out with having the best Recoil Control in Armored Core 6. In fact, the lead in this category is so massive that it’s a no-brainer option for players who use Assault Rifles or Grenade Launchers as part of their weapons kit.

Following the CC-3000’s chest, here is the procedure to find the next Wrecker armor piece:

  1. From the ground floor, ascend back to the lava chamber, and you’ll see a large pipeline next to it.
pipeline grid 086 vents
Pipeline near the chamber (Screenshot Captured by eXputer)
  1. Enter the pipe, and as you follow it, you’ll eventually face Nosaac, an enemy AC defending the AC-3000.

2C-3000 WRECKER

AP 4220
Anti-Kinetic Defense 350
Anti-Energy Defense 312
Anti-Explosive Defense 383
Attitude Stability 943
Load Limit 68900
Jump Distance 76
Jump Height 17

The WRECKER parts have generally been promising thus far, but the 2C-3000 Bipedal leg component is not an armor piece I would recommend in Armored Core 6. Mainly developed for mid-weight builds, the 2C-3000’s strong suit is its Anti-Explosive Defense. But aside from that, its weak Attitude Stability, Load Limit, Jump Height, and Jump Distance make the 2C-3000 a tough sell.

Use this procedure to get the final WRECKER piece after the AC-3000’s retrieval in the pipelines:

  1. Carefully maneuver back out of the pipe and access the main exit to continue the mission.
main exit door grid 086

  1. Once you’re at the platform of your concurrent objective, follow the rails on the right from where you can see the RaD logo on the wall in the distance.
railings grid 086

  1. These rails will take you directly to the 2C-3000, but you’ll encounter an ambush almost immediately after you pick the hidden part.

Tunnel Sabotage

Chapter 3 is home to several hidden weapons in Armored Core 6, and the first one you’ll get is in the Tunnel Sabotage, one of the earlier missions in this chapter. When going for the hidden part’s chest, I’d strongly recommend avoiding unnecessary battles since you’ll use most of your Repair Kits later.

IA-C01W1: NEBULA

Attack Power 528
Impact 198
Accumulative Impact 132
Blast Radius 20
Direct Hit Adjustment 125
Recoil 15
Effective Range 460
Rapid Fire 1.5

As your first hidden weapon, the IA-C01W1 NEBULA is a right-handed plasma rifle that shoots continuous energy rounds with rapid fire. Like most energy-based weapons, you can charge the NEBULA’s shots for heavier damage output and a larger blast radius. Given its stat, the IA-C01W1 is a great weapon for long-range and close-quarters combat against hordes of weaker MTs and even against low-mobility bosses if you’re always charging up your attacks.

Once you boot up the Tunnel Sabotage mission, here’s what you need to do:

  1. Go into the underground tunnel and follow your objective markers until you reach a series of elongated runways.

  1. From here, get on the first runway and ascend to the upper runway labeled “DXRH-MU-59.”

  1. Once you’re atop, head left and take out the enemy MTs, prioritizing the sniper MT at the back of the area.
  2. After taking out the laser-shooting mech, you’ll see yet another runway behind it labeled “DGS2337,” carrying the chest you’re looking for.

Survey The Uninhabited Floating City

For this mission later in Chapter 3, you’ll spend most of your time turning off the ECM fog control devices to make the area accessible. Since there are no objective markers here, you must follow the red pulsing beacons placed in succession. Fortunately, these beacons will help you to complete the mission quickly and obtain the hidden part here.

IA-C01G: AORTA

IA-C01G AORTA ac6

EN Capacity 3000
EN Recharge 238
Supply Recovery 333
Post-Recovery EN Supple 2000
Energy Firearm Spec. 105

As the name suggests, the IA-C01G AORTA is a capable Generator part for your mech in Armored Core 6. Despite its low Weight requirement, the AORTA packs one of the highest EN Capacities and Post-Recovery EN Supplies in-game. However, with its relatively low EN Recharge and Supply Recovery, I’d recommend this component to players who like to expend their stamina meter all at once rather than in small bursts.

Here’s a quick procedure to get the AORTA Generator in the Survey The Uninhabited Floating City mission:

  1. As mentioned earlier, follow the red beacons placed on the ground, which should take you to your first objective – an ECM Fog Control Device.
  2. After accessing and shutting down the device, follow the beacon path in the northwestern direction, leading you to an oval-shaped building just before the next Fog Device.

  1. Get onto the building, and your HUD will highlight the chest at the rooftop’s edge.

Eliminate “Honest” Brute

Taking down Honest Brute is a vital part of Chapter 3, as you’ll need the weapon he’s guarding to kill the Ice Worm. Besides that, however, you can also get some uniquely powerful hidden parts in various locations of this area, ranging from a chainsaw to a booster to the only flamethrower available in Armored Core 6.

WB-0010 DOUBLE TROUBLE

The WB-0100 DOUBLE TROUBLE stats (Image Credit Copyright: eXputer)
Attack Power 1025
Impact 750
Accumulative Impact 375
Consecutive Hits 2
Direct Hit Adjustment 270
PA Interface 119
Cooling 302

The DOUBLE TROUBLE is the only chainsaw melee weapon in AC6, which you can drill into an enemy for insane AP and Posture Damage. You can pre-emptively charge up the chainsaw for a better attack window, but dashing or sprinting during that time will cancel out the charge. As such, if you want to use the DOUBLE TROUBLE, it’ll be most effective for close-ranged builds against slow-moving bosses or staggered enemies.

Upon starting the mission, proceed as per the steps below:

  1. For the first half of this search, keep following the objectives and dropping down from platform to platform.
  2. Once you’re on the second subsequent floating platform, look below from different angles until you spot another platform infested with red-laser sensors.

  1. Jump down to the targeted area while avoiding the sensors and access the chest on the far edge.

BC-0600 12345

The BC-6000 12345 Booster stats (Screenshot by eXputer)
Thrust 5801

Upward EN Consumption 800
QB Thrust 18900
QB Jet Duration 0.54
QB EN Consumption 520
AB Thrust 8084
AB EN Consumption 372

For using your Quick Boost and dashing around enemy attacks, the BC-0600 is your best bet. This is mainly thanks to its QB Jet Duration, QB EN Consumption, and QB Reload Ideal Weight, which are superior to any other in-game booster. As such, low-AP builds might want to consider the BC-0600 for these crucial advantages.

After picking up the DOUBLE TROUBLE, follow these instructions:

  1. Again, while avoiding the sensors, keep descending to the next objective marker below.
  2. Upon reaching the next platform, progress along the narrow path on your right, and you’ll end up with the booster’s chest atop a giant mechanism of the extreme edge.

WB-0000 BAD COOK

 WB-0000 BAD COOK armored core 6

Attack Power 85
Impact 3
Accumulative Impact 1
Blast Radius 15
Direct Hit Adjustment 115
Recoil 10
Effective Range 200
Rapid Fire 8.4

The BAD COOK is a right-handed flamethrower weapon that, like the DOUBLE TROUBLE, can be highly lethal at close range. If you have a quick AC that can close the gap between you and hostiles, this is an ideal choice for that playstyle. However, it’s worth mentioning that the WB-0800 BAD COOK does not inflict any posture damage, so you’ll need to rely on your left-hand and shoulder weapons to create an ACS Overload.

Without further ado, here’s how to get this flamethrower after taking the BC-0600:

  1. As you advance through the mission, you’ll reach a tightly packed room with several red-laser sensors.

  1. Drop down and immediately remove all the sensory mechs and light MTs while dodging incoming attacks.
  2. Once the room’s clear, you can safely access the BAD COOK’s chest in the center.

Underground Exploration – Depth 1

Following the defeat of the Ice Worm boss that concludes Chapter 3, your subsequent few missions will primarily center around exploring a deep cave and retrieving further info on the Coral. Chapter 4 contains the complete Ephemera set in Armored Core 6 and additional hidden parts in distinct locations, like a pair of boosters.

IA-C01L Ephemera

IA-C01L Ephemera leg part

Anti-Kinetic Defense 297
Anti-Energy Defense 352
Anti-Explosive Defense 352
Attitude Stability 755
Load Limit 55050
Jump Distance 99
Jump Height 27

As the first part of the Ephemera collection, the IA-C01L is a great lightweight Bipedal Leg set, massively outperforming other Legs in its weight. It’s a great addition to builds that prefer solid maneuverability and responsive dashes. However, it slightly falls back on its Jumping Height and Distance and gets outshined by several similar Bipedal and Reverse-Jointed legs.

Players must reach the Underground Exploration – Depth 1 Mission after completing Chapter 3 and perform the following steps:

  1. Access the elevator at the beginning of the mission to descend to the site’s bottom.
elevator mission 28
Accessing the Elevator (Image Credit Copyright: eXputer)
  1. Once the elevator stops, drop down to the nearest platform while avoiding enemy lasers shooting from below the site.
  2. After navigating through the area, you will be attacked by several enemy MTs, after which Ayre will guide you to the nearby Access Point, your next objective.

  1. Finally, you can access the chest at the far end of the window to obtain the IA-C01L Ephemera.
chest mission 28 ac6

Underground Exploration – Depth 2

After getting the IA-C01L Bipedal Legs, you must proceed through Depth 1 and kill Nephentes, the giant mechanism at the bottom of the area. Target its neck by getting close to its head, and you’ll wipe out its reasonably low HP with a few attacks, prompting you to Depth 2.

IA-C01B Gills

gills booster
The IA-C01B Gills stats (Screenshot Grab: eXputer)
Thrust 6317
Upward Thrust 5001
Upward EN Consumption 580
QB Thrust 18850
QB Jet Duration 0.28
QB EN Consumption 620
AB Thrust 0.30
AB EN Consumption 68300

The Gills are some of the best lightweight boosters in AC6, providing the best stats for Upward-related thrust and mobility compared to other boosters in their weight. Despite the balanced toolset as its primary selling point, I would not recommend the IA-C01B for melee builds due to the extremely weak Melee Thurst.

Upon entering the second Depths, you can get the IA-C01B with this procedure:

  1. Start by accessing the door in front, slide down the shaft, and destroy the approaching MT.
  2. Now, go through the tunnel on your right and enter the small room on your left as you exit the tunnel.
  3. Drop down from the opening inside the room and kill the surrounding Balam MTs, then head outside and access the Control Panel.
Control Panel Underground Depths 2

  1. Once the power’s back online, use the elevator beside you to ascend back up to unlock the locked door.
  2. Continue following the tunnel, and you’ll eventually face G5 Iguazu, a quick-moving AC miniboss from the Redguns.
g5 iguazu

  1. After dealing with him, resupply and advance further in, after which you must chase after the laser-shooting MT into a tunnel.
  2. After you spot that MT again in the tunnel, go into the room on your right, and you’ll find the chest with the booster inside.
Gills boosters location

IA-C01A Ephemera

ephemera arm component ac6
The IA-C01A Ephemera stats (Screenshot taken by eXputer)
AP 2380
Anti-Kinetic Defense 219
Anti-Energy Defense 263
Anti-Explosive Defense 256
Arms Load Limit 12680
Recoil Control 98
Firearm Specialization 104
Melee Specialization 106

Designed for lightweight build users, the IA-C01A are great arm attachments if you can keep up with the high EN load requirements. It comes with great AP and Defenses, but I would suggest this component for its excellent Melee and Firearm Specializations, beating out some of the top heavyweight arms as well. 

For the IA-C01A Ephemera, follow these steps after obtaining the Gills booster:

  1. Upon opening the chest, sprint back outside the tunnel and carefully drop to the rocky platforms near the entrance.
  2. Eventually, you’ll reach the Ventilation Duct and encounter some Electricity-Discharging drones.

  1. Ignore these drones, use the launch pad in front, and then grab the arms’ chest after reaching the uppermost level.
ephemera arms ac6

Underground Exploration – Depth 3

With the arms in possession, continue through the series of tunnels in Depth 2 until you reach the Enforcer boss fight. This boss has several melee-oriented attacks, using laser slashes and sometimes creating an AoE blast with its weapon. You might need some additional attempts before you figure out its moveset, and once you do and kill it, you’ll advance to the final Depths mission.

IA-C01F OCELLUS

IA-C01F OCELLUS Armored Core 6

Close-Range Assist 90
Close-Range Assist 12
Close-Range Assist 3
Missile Lock Correction 85
Missile Lock Correction 50

Mainly on the heavier side regarding Weight and EN Load, the OCELLUS is an FCS as part of your mech’s Inner Components with the best close-range assist in Armored Core 6. The IA-C01F is the only FCS that’s a hidden part in-game and is the ideal pick for players who utilize shotguns, melee, and other lethal weapons at close range.

    • Of course, this significant advantage has a noticeable drawback: the OCELLUS has the worst Medium-Range and Close-Range assists.
    • Furthermore, its Missile-Lock and Multi-Lock corrections leave much to be desired, limiting the OCELLUS’s versatility and making it a suitable addition to particular builds and playstyles.

With the third Depths entered, proceed through the area for the OCELLUS in the manner below:

  1. After accessing the initial door, traverse the rocky platforms until you spot the circular Reactor.
reactor underground exploration depths 3
Depths Reactor (Image Credit Copyright: eXputer))
  1. Follow the objective to the platforms below, then use the walls to avoid incoming lasers.
  2. Sprint to the next platform’s upper level on your right and go behind the artillery equipment to spot a chest with the IA-C01F inside.

Anti-Kinetic Defense 335
Anti-Energy Defense 452
Anti-Explosive Defense 430
Attitude Stability 363
Booster Efficiency Adj 101
Generator Output 126
Generator Supply 96

The IA-C01C is a Core and another lightweight hidden part from the Ephemera family, but it has a distinct quality that makes it an easy sell. This Core component has unmatched Generator Output Adj., which can boost your maximum EN Capacity by the widest margin. With it, you won’t have to use COAM on expensive Generator parts with massive EN capacities and can then utilize the Ephemera’s Core to prevent any EN Shortfall.

Starting from the OCELLUS’s chest, here’s how to get the Ephemera’s Core component:

  1. Drop down to the platform’s lower level and quickly make your way to the Reactor’s circular base, where the lasers are situated.
  2. Once you reach the base, destroy the laser-shooting artillery as quickly as you can to avoid taking any unnecessary damage.
  3. Next, go around the base from the right side until you spot the Ephemera’s crate at the end of a walkway.

  1. Eliminate the PCA MT guarding the crate to get a Combat Log for your LogHunt program, and access the container itself to obtain its hidden part.

Unknown Territory Survey

Unknown Territory Survey is where you’ll complete the Ephemera set by getting its head armor. The mission itself is relatively easy, with little to no challenging enemies, including the boss and the new objective towards the end.

IA-C01H Ephemera

Ephemera Armored core 6
The IA-C01H Ephemera Stats (Screenshot Grab: eXputer)

Anti-Kinetic Defense 160
Anti-Energy Defense 189
Anti-Explosive Defense 186
Attitude Stability 480
System Recovery 132
Scan Distance 550
Scan Effect Duration 4.8

If you’re looking for a great all-around helmet with minimal drawbacks, the Ephemera is for you. This is largely considered one of the best heads in AC6 since it has unbeatable Anti-Energy and Anti-Explosive Defense. Besides that, it’s got solid AP and Attitude Stability, and since you get the Ephemera helmet for free, there’s no reason not to get it.

Once you’re at the Unknown Territory Survey Mission in Chapter 4, complete the steps below:

  1. Jump down from the Reactor base to the next Depths onto the waste-filled puddle below.
unknown territory survery mission ac6
The next Depths (Image Captured by eXputer)
  1. Proceed down the unknown territory through the narrow path and avoid the Mealworms infesting the area.
  2. Maintain a safe distance from these creatures, as they explode almost instantly when you’re too close.
  3. After traversing further into the cave, you’ll spot a crate next to some Mealworms, opening which will give you the IA-C01H Ephemera.

Reach The Coral Convergence

As the final mission in Chapter 4, reaching the Coral Convergence is also arguably the most challenging mission so far, mainly due to the Cel-240 boss fight at the end, largely considered the hardest boss in Armored Core 6. Fortunately, you can earn a hefty amount of COAM here, as well as a potent pair of weapons for your mech.

IA-C01W3: AURORA

The IA-C01W3 AURORA is a right shoulder weapon that shoots four energy rays that converge to a single point. It comes with respectable damage, range, and reload time, making the AURORA an ideal weapon against fast-paced in-game bosses. To see how it fairs against other missile-like armaments, you can experiment with it in the AC Test section under the Sortie menu.

Here’s how to get the AURORA, starting from Chapter 4’s Reach the Coral Convergence mission:

  1. From your spawn point, move right until you’re next to the zone restriction barrier, and now head straight while sticking close to the border.

  1. Eventually, you’ll reach a broken-apart landmass adjacent to your current mission objective, where you’ll spot the AURORA’s chest on a small building.

Custom to FromSoftware’s tradition, the “Moonlight Greatsword” makes an appearance in AC6 in the form of the IA-C01W2 Moonlight. This melee weapon shoots two diagonal slash attacks or can be charged to perform one massive horizontal wave of light. The IA-C01W2 is one of the most lightweight melee weapons you can use at a distance, but as a drawback from its weight, it also has mediocre damage output.

After killing G3 Wu Huahai and V.VI Maeterlinck, here’s how to get the Moonlight weapon:

  1. Move towards your next mission objective until you reach the end of the road and spot a bridge in the distance.
reach the coral convergence mission
End of the road (Screenshot taken by eXputer)
  1. Drop down to the shallow waters below and continue straight ahead to the next marker.
  2. Here, you can kill the wheel-like MTs covering your path to gain additional Combat Logs or ignore them entirely by staying at elevated ground.
  3. Near the end of the bridge’s foot, you’ll find the MOONLIGHT’s stash surrounded by 4 MTs.

Regain Control Of The Xylem

Regaining control of the Xylem is the last and only mission in Chapter 5 in Armored Core 6 with any hidden or secret parts, but unlike the other missions on the list, you’ll need to get to NG++ in order to access this mission in the campaign. Furthermore, there are some prerequisites to the Xylem mission, as you must choose the “Eliminate V.III” Decision Mission in Chapter 4 beforehand.

IB-C0W3: NGI 006

Attack Power 827
Impact 720
Accumulative Impact 720
Blast Radius 36
Direct Hit Adjustment 185
Guidance 110
Effective Range 1000

As one of the few left shoulder secret parts, the IB-C0W3 NGI 006 is an exceptionally powerful Coral Missile Launcher in Armored Core 6, launching a missile that tracks the enemy. It provides decent Attack Power and Reload time, but its primary specialty is the Effective Range, making it the recommended choice for most long-range ACs that utilize their arsenal from a safe distance.

Once you commence the mission, simply perform the following steps:

  1. Drop down from the slit on your left onto the ground floor.
  2. Head straight, and you’ll see the NGI 006 chest stashed in the corner and surrounded by two drones.

IB-C03W4: NGI 28

Damage Mitigation 55
Impact Dampening 50
Deployment Range 360
Cooling 100

The NGI 28 is another Coral Weapon found in the same mission, which you can use instead of the NGI 006 if you’re a defensive player. This unit deploys an effective Coral Shield, offering one of the best Deployment Ranges and Damage Mitigations over any shoulder-attaching shield in Armored Core 6. As a bonus, it’s also reasonably lightweight, making it versatile and accessible.

Upon getting the NGI 006, here’s the method to getting one of those secret Coral parts in Armored Core 6:

  1. Continue following your objective markers by taking down the parasite modules inside the Xylem ship.
  2. After killing the third module, you’ll go through a narrow pathway, where you must jump down to retrieve the chest on the ground floor near the ship’s center.
