Armored Core 6: All Combat Logs in Chapter 4

In Chapter 4 of Armored Core 6, we go deeper into Rubicon and eventually find Institute City. On the way there, we’ll also stumble upon multiple enemies that hold Combat Logs. Defeat these enemies and collect all the Combat Logs in the game to obtain a trophy or achievement.

Underground Exploration – Depth 2

There are three Combat Logs in this mission. One of them is unmissable. The other two aren’t, but they’re also not that easy to miss.

Gold Log

You’ll face G5 Iguazu as you progress through this mission. Iguazu is an unmissable mini-boss. Defeat him to get a Gold Log.

Bronze Logs 1 & 2

After defeating Iguazu, continue onwards and you’ll come across a defense AC on a bridge. This AC will hop off this bridge and fly off to another one far to the right. Follow the AC to the next bridge.

From here, proceed to the tunnel ahead. When you get to the area where a blast door closes in front of you, make your way to the room on the right. You’ll find two AC enemies here. Defeat them to get Bronze Logs 1 and 2.

Underground Exploration – Depth 2 ALT Mission

The ALT mission for Underground Exploration – Depth 2 becomes available during New Game ++ if you’ve unlocked the first two endings already. There’s only one Combat Log here and it’s unmissable.

Platinum Log

Progress to the area where Iguazu is supposed to be and you’ll find that another AC will ambush you instead. This AC is called Deadsled—which is piloted by Coldcall. Defeat him to get a Platinum Log.

Underground Exploration – Depth 3

There are three Combat Logs in this mission. Getting to the first two is tricky. Either equip a build that has a high AP and defense or quickly get through the area in the mission where multiple lasers are being shot at you.

Bronze Log 1

Get to the main reactor area. Once you make it to the area where the snipers fire lasers at you, make your way to their platform and continue heading right.

To make things easier for you here, destroy some of the snipers so they won’t damage you further as you make it to the combat log. Keep going until you see a lone AC on a bridge with a log sign on it.

Bronze Log 2

From the previous log, continue heading to the right and you’ll find another lone AC on a bridge with a log sign on it. Eliminate it to get the second Bronze Log.

Gold Log

When you make your escape after destroying the pressure chamber, you’ll be halted by an AC named Ephemera. Destroy it to receive a Gold Log. This enemy is unmissable.

Intercept the Redguns

This mission is particularly challenging. Thankfully, the Combat Log for it is unmissable.

Platinum Log

As you finish off waves of enemies during this mission, G1 Michigan will eventually join the fray. Defeat him to receive the Platinum Log.

Ambush the Vespers

This is a short mission that has you defeat two Vespers alongside an ally AC.

Gold Logs 1 & 2

The enemies you’ll fight in this mission are V.V Hawkins and V.VIII Pater. You’ll receive Gold Logs for defeating them.

Eliminate V.III

This is yet another short mission where you only fight a single AC. This mission, however, is only available in New Game ++ when you’re on the path to unlocking the third ending of the game.

Platinum Log

V.III is the only enemy in this mission. Defeat him to receive the Platinum Log.

Unknown Territory Survey

The first half of this mission is simply getting from point A to point B, and the second half is fighting a named AC. Just stick to the main objective and the Combat Log is all yours.

Platinum Log

The boss at the end of this mission is V.IV Rusty. You’ll receive the Platinum Log after defeating him.

Unknown Territory Survey ALT Mission

This is the same exact mission as before, except you fight two bosses at the end instead of one. This alternate mission is exclusive to New Game ++.

Gold Log

Middle Flatwell will join Rusty a few moments after the battle begins. You’ll receive a Gold Log for defeating him.

Reach the Coral Convergence

There are many Combat Logs in this mission—13 to be exact. The enemies themselves are easy to find, but defeating all of them in one playthrough can be tough.

Gold Logs 1 & 2

The first two objective targets you need to eliminate at the beginning of the mission are V.VI Maeterlinck and G3 Wu Huahai. Each of them drops a Gold Log.

Bronze Log 1

After clearing the first area, progress through the mission until you reach a bridge. Once here, a Grinder Wheel will attack you. Defeat this AC to get the first Bronze Log.

Bronze Logs 2 to 9 (8 Total)

There are eight Grinder Wheels on the ground under the bridge and each of them holds a Bronze Log. If you’re unable to defeat all eight, eliminate as many as you can and finish the mission. Start another run and destroy the Rollers you haven’t in the previous run to collect all the Combat Logs in this area.

Tip

The Grinder Wheels are extremely weak to explosive damage. Use weapons such as the Songbirds back units or any explosive missile launchers for an easier time taking out these fast and tough enemies.

Silver Logs 1 & 2

From the ground, head to the side of the bridge near where the objective marker is located. Once there, make a right and you’ll find a wrecked building. You’ll find a Data Log on a fallen AC here.

Interact with the Data Log and two machines nearby will activate and begin attacking you. Defeat them to get two Silver Logs.

Tip

Both of these ACs are also very weak to explosive damage.

Remember that you’ll need to complete each mission to actually obtain the Combat Logs after defeating the machines that hold them. That means, for the last mission in Chapter 4, you’ll need to beat Ibis again—which is arguably the toughest boss in the game.

You’ve done it before, so you can do it again! All the best to you, 621.
