Any mission omitted from this guide has nothing in it. No logs, no hidden parts. From the start of the guide, I will list everything for convenience in case you want to cross reference what you may or may not have. Below will be mission specifics, also for the sake of cross referencing. Make good use of the index on the right.

These are all the parts as they appear in order. All but the last two coral-based weapons can be obtained on your first playthrough.


Mission 52 is NG++ only.

While you can complete the Records Arena in NG, Analysis Arena only opens in NG+.
Analysis Arena δ opens in NG++.


You can get enough OST Chips to fully upgrade your OS, but it requires NG+'s Analysis Arena.

Unlike Data Logs or Hidden Parts, Combat Logs actually tell you what missions they're on and if you still have more to find making them a bit easier, but some can be sneaky nonetheless. Looking at you, Ring Freddie.


Rank 14 is only obtainable in NG+
Rank 15 is only obtainable in NG++.

These are all the data logs as they appear on the in game list. This is for your benefit, making it so you can easily cross reference this and your own list to see what you may be missing. When they appear in game, however, is wildly different, so make good use of the mission specifics below.

There is exactly 50 data logs.

Follow the mission objective, impossible to miss. Found on the same raised area where you had found Raven's License. Destroy the other MTs first to make it a little easier.

Follow the mission objective.

After destroying the second target, instead of moving up towards the third target, keep to the right instead.

While Dunham is actually optional, he is hard to miss, appearing before the destruction of the final target.

This alternate mission is NG+ only.

Follow the mission objective, until you're offered more money. Only Volta will give a log, as you have Iguazu's already.

On the left side past the first wall, this set of enemies are surrounding Volta's wreck.

Follow the mission objective.

Relative to facing the wall, Volta's destroyed AC can be found to the very left of the city surrounded by 3x Light MTs.

Relative to facing the wall, this wreck can be found to the right where the two walls meet, on top of the smaller wall and tucked away into a corner.

Drop into the large canyon area while perusing for more data logs. She will attack you for your role in Operation Wallclimber. As she's just a child, make sure to use a pilebunker on her.

The first data log you'll likely see out in the open, just beneath where you start.

Located almost immediately next to the first data log.

Continuing along the right, you'll find this flaming wreck guarded by three MTs.

Visible from the previous wreck.

Directly next to the previous wreck. MTs spawn on approaching it.

After getting the previous log, jump into the hole immediately. It'll be right at the bottom.

On the other side of the massive piece of slag from the grid is this wreck. Getting close to it will spawn Ziyi.

This wreck is easily missed compared to the others, located underneath the grid's massive dropped slag, it's underneath on the upper ledge guarded by few MTs.

This mission is NG+ only.

Follow the mission objective to the first point, and then push further forward and destroy the larger choppers on a nearby building. Make a solid turn left and head back up onto the raised natural area.

Follow the mission objective. Make sure to destroy the MTs first.

After destroying the first MDD, drop down to the bottom level and stick to the right wall. This wreck will be guarded by another MDD.

After the second MDD encounter, stick to the upper left area. There will be yellow cranes built into the wall with this wreck on one of the last ones.

Follow the mission objective.

Just past and beneath the second laser cannon, there is a hole that drops down to a small water section where this wreck hides.

After clearing the first area, this wreck can be found in between the first and second areas on the highest building. For added context, Sulla would be in the third area.

From the door where two Toybox MTs drop down behind you as a trap, go forward and drop down through the hole. Immediately turn around and its' in the corner.

In the furnace area, denoted by the molten metal, jump past the crucible into an area below. Be wary of multiple MTs laying in wait as a trap.

In the same location as Enemy AC: Nossa. In the furnace room, there are two pipes with one pouring molten lava into a cruciblel. Enter the inactive pipe and make your way through to the end of the path.

In the final area past the furnace, stick to the right side of the final structure. This is located directly above the final combat log. This is just before the fireworks.

Follow the mission objective.

After defeating Rummy, exit the opened door. Immediately fly up onto the roof of Rummy's area and the two will be here.

After defeating Rummy, exit the opened door. Immediately fly up onto the roof of Rummy's area, then go past the BAWS Tetrapods and over the larger structures with MTs on it. You'll come to a large lift with the two Toybox MTs beneath you.

In the same location as AC-3000 WRECKER. In the furnace room, there are two pipes, one still active with molten metal. Enter the inactive pipe and make your way through to the end of the path.

In the final area past the furnace, stick to the right side of the final structure. This is located directly underneath the 2C-3000 WRECKER legs. This is just before the fireworks.

After "Invincible" Rummy, proceed out the opened door. Turn around, jump up, and pass over the top to the large lift area This is past both the 2x BAWS Tetrapods and 2x Toybox MTs, at the bottom of the large lift.

In a similar location to AC-3000 WRECKER and Nossa. In the furnace room, instead of entering the empty pipe, instead enter the very much active molten pipe. This will cause damage.

This mission is NG+ only.

You'll likely find this fairly easily while looking around for the hacking devices, as it's blocking a path right to one.

Found in the same location that Nossa, or AC-3000 WRECKER, was. Same pipe next to the crucible. There are several Suicide Drones inside, so be mindful of them first.

Follow the mission objective.

After stopping the hack, do not exit the area. Instead, go to the area right of the exit objective, and inside will be this wreck. Remember, the 02 door, not 01!

After the lift, keep to the right and drop down to a lower platform. The second data log for Doser Chatter is here as well. After collecting the data log, turn around and simply pass through this tunnel.

After the lift, keep to the left and drop down. So long as you're by the edge, you'll find the lower area with this wreck easily.

After the lift, keep to the right and drop down to this lower platform. On the lower platform, you'll find this wreck near some Squid Drones.

From the start of the mission, keep to the right and keep going. It's past the first large building.

These two are near the bridge, one directly underneath it, and the other off to the right by the struts in the canyon on the right side.

Halfway through the mission on the bridge with gatling guns, beneath this bridge and to the right is a small, closed entrance. Sitting just inside is this wreck.

At the final objective, the actual fuel refinery, jump over it and squeeze in between the dome and the wall. Inside this small gap is the wreck.

Follow the mission objective and stop at the first point. From here, you should be able to see it in between some buildings. The second data log is also here.

Follow the mission objective. When he offers you money, he stops moving, despite pilebunkers existing.

When Swinburne offers you money NOT to crush him with a pilebunker, accept his offer. Roku will appear and angrily, offering himself up to the pilebunking Gods.

Immediately after starting, drop to the base of the wall to your right and travel along it. You'll come to a small ramp down and this wreck.

In front of the BAWS Tetrapod within the city, near the first objective.

After entering the larger, open area of the cave with large struts crossing the chasm, head up and to the left. In this pocket area, you'll find this part in front of a large machine.

Located on the way to NEBULA, this will be in the upper left area after entering the larger open area of the cave.

After accessing the first ECM Fog Generator, head towards the second one. This part will be located just before the second objective on top of a short building.

After the second Fog Generator, head down the road towards the two plasma launchers. After dispatching them, continue following the road without turning. For a better vantage, get onto the bridge where one of the Transforming MTs were. You should be able to see the teal eye of the Combat Log MT, and next to it is Domayan's Writing (3).

Upon mission start, head to your right instead and go around the hole. Hidden behind a ledge towards the end of the area is CANDLE RING. Should you go for the data log instead, he will ambush you.

Opposite of Ring Freddie, away from the hole and up against the cliff, is this wreck.

While moving up to the base, keep to the left wall. This wreck is just inside a gate.

By the rightmost target, there is a smaller complex that these two watch over and patrol.

Distant from any targets, this LC is found left of the rocket, relative to your starting position.

On the fourth hanging structure, this part can be found straight down from the Coyote Chatter data log.

On the seventh hanging structure, on the farther end that stretches far out.

After going into the structure beyond the Shield Generator Toybox MT, simply drop down and look to the right. Incredibly hard to miss.

On the fourth hanging structure near the first part, as well as the fifth, these two are rolled up and waiting.

On the seventh hanging structure, towards the center. Can't miss it.

I don't think anyone will miss this one.

Follow the mission objective.

At the very start of the mission, you will be facing the third hanging structure. The data log is at the very top platform you're looking at from the start.

After dealing with the large shield, turn back out directly towards the open area. At the very bottom of the eighth hanging structure, this wreck will be a bit more visible with electricity against the dark surfaces. Be wary of the two MTs directly above it.

Follow the mission objective.

After entering the chasm and chasing down the boss with the door locking on you, the part will be in the room directly to your right.

After entering the pipe and hitting the vertical jump pad, it's directly in front of you. This is the opposite of a hidden part.

Follow the mission objective. This wreck will be in the same room as Coldcall on the ramp down.

Upon entering the cavern, this part will be to your right on the further outer platform just behind an obstacle.

Found on the far left strut, this part is guarded by one of the two Combat Log enemies.

These two are separate, but can be found on the opposite end of the cavern on two different struts.

Follow the mission objective.

Upon entering the large cavern, this data log will be on the strut to your left, closer to the cave wall.

On the far right edge from the start on a smaller building.

Upon reaching the water, this part can be found on the far left side of the bridge. Be warned as it's surrounded by Wheels.

Follow the mission objective.

Located exclusively in the water area, there is a group of three immediately upon dropping in, two more in the distance, then three more surrounding the MOONLIGHT. The final wheel spawns when trying to cross the bridge in the water.

Normally, I would not recommend means of dealing with something. However, SONGBIRDS Grenade Launcher is notably very effective against them, able to destroy one in one shot if it's headed towards you.

In the water area on the far right end. Collecting the Data Log will activate two C-Weapons around you. However, you can also shoot one individually, activating them one at a time to make them easier to deal with.

Immediately upon starting, look to your left. It's on top of the tallest building.

It's worth it.

Upon starting the mission, simply drop down to your left and go straight.

That's all.

In the third room, with the fifth and sixth target, this part is in the first half of the room towards the center.

I want to thank everyone for the awards and all the positive ratings, helping this become the top rated guide, keeping it visible for years to come.

Armored Core has been my favorite franchise since PS1, so it's important to me that I can help others enjoy it in some way.
