Industria 2 – A Change Of Plan Walkthrough

Now that you have miraculously managed to escape, follow the path ahead, and near the crashed truck, there will be some enemies. These will not be the humans who captured you, but instead, there are going to be the same AI monsters. You will have all of your weapons, so take care of the monsters and go straight ahead through the broken wall.
Once you are inside, you will notice a communication device on the left side. Interact with it if you want, or you can simply head up the stairs to continue progressing. Follow the path ahead, and you will find a fabricator that you can use to upgrade your weapons.
Since you fought the brute and other monsters earlier, you should have plenty of points to upgrade your weapons or buy other useful items.
Defeat The CDR Agents

Once you have upgraded your weapons, go ahead and open the door. You will then hear GDR Agents nearby. Open the door on the left and take both of them out. Note that they will not go down in a single shot and are equipped with weapons, so be careful during the fight.
After defeating them, you can loot the ammo they drop. Once you have defeated them, head right and enter the elevator. Then interact with the lever to go up. Once you are up, go ahead, loot the area, save your progress, destroy the plank, and continue forward.
Making Your Way To Balstad

After destroying the plank, do not go straight north, as that can be dangerous. There are enemies ahead, so instead of going to the northeast side, head slightly to the west and then go through the broken wall.
You will then enter a room where you can find some loot. Once you have looted the room, look through the circular gap in the wall, and you will notice some enemies. Equip your rifle and shotgun, and start shooting them. Make sure to use your rifle on the ones that are out of range of the shotgun.
After defeating them, head to the other side and follow the path while looting everything. You will then have to defeat some more enemies, and once you have done that, on the north side, there will be a locked gate. You need a password to enter, and you will get that soon, so do not worry.
Find The Password To Open The Gate

Then follow the path to the left, go through the hole in the wall by crouching, and ahead you will find the enemies you defeated earlier. Pick up their drops, head up the stairs, loot the room on the right, go ahead, and enter the second room on the left.
Then enter another room on the left, and inside you will find the code to open the gate. So head back to open the gate, but keep in mind that you may encounter more enemies along the way. Be careful and defeat them. Once done, use the combination to open the gate and go through it.
Loot the area and interact with the gate ahead, and you will be inside a cave.
Explore The Balstad Mines

Once you are in the mines, follow the path ahead and then go left. Just a little further ahead, there will be a room on the left where you can save your progress. Then head left again, and there will be a lever. Interact with it, and there will also be a communication device to its right.
So, if you want to interact with it, do so and then head out of the room. Go right and follow the path to the left. Then open the sliding gate on the north side and pull back the cart. Once done, interact with the lever. Upon doing so, you will go up. Then go ahead, and there are going to be some monsters.
Defeat The Monsters To Keep Proceeding

Defeat the monsters, go ahead, and then instead of going down the stairs, head left and shoot the monsters first. At the end of the path, you will be able to see them clearly, so deal with all of them. There are going to be a lot of them, so you can use a pipe bomb if you want.
Then jump down and move ahead. If you stay in the same place, more monsters will come, so make sure you keep moving. Keep going forward, where there will be more of them. However, you can ignore them and jump onto the platform. This will prevent them from approaching you.
Take Care Of The Agents

Next, drop down and follow the path ahead to find some agents. You now need to defeat them, but make sure that you do not go into the middle of the area. Once you have defeated them, follow the path to continue progressing. However, do note that when you enter the area on the left side, there will be plenty of loot. So collect all of it before moving on.
Ahead, you will notice a green light. Go there and pull the lever. Then wait for the elevator to come up, and when it does, enter it and pull the lever. When you are at the bottom, go ahead, open the sliding door, and you will go further down.
Head To The Atlas Core

You will now be near the Atlas Core, so it is time to head there. Go up the stairs, open the door ahead to save your progress, and upgrade your weapons. There will also be some loot in the area, so make sure you collect that as well. Then follow the path ahead, defeat some monsters, and keep going.
Do note that there are going to be a lot of monsters here, and among them, there will be some carrying guns. You need to be careful and stay in cover while fighting them. I recommend using a bolt-action rifle to knock down some of them and then using a different weapon to finish them off.
When they get too close to you, make sure you have the shotgun equipped. Then follow the path ahead, head right, and take the first left. You can also explore the other sides to get additional loot and then come back here.

Ahead will be more monsters. Take care of them, then head left. Take another left and then go right. On the opposite sides, you will find some loot, so if you need any supplies, make sure to explore. Then go ahead, and in the room to your left, you will find a note with a code written on it.
Open The Door Using The Combination

Now you need to head back to where you fought many of those monsters after getting out of the elevator. Go ahead, and then there will be a broken staircase on the right side. Jump onto it, and ahead there will be a shutter door that you need to open using the combination mentioned on the note.
Then follow the path ahead, and as you go through the narrow gap, a conversation with Walter will be triggered. Once the conversation is over, defeat the monster and keep moving forward. On the way, on the left side, there will be a door, so interact with it.
Then go ahead, loot the area, open the sliding door, and interact with another door ahead. Then move forward and head left to find the safe area. Save your progress, upgrade your weapons, head out, and then go up to the platform on the left side. It will be on your left as you exit the narrow passage.
Defeat The Agents And Keep Progressing

Ahead, you will find some agents. Take care of them. One of them will be on the upper level where you are, and the other one will be at the bottom. So defeat the one below from above, then follow the path to the left to find an item. This item will come in handy later, so pick it up and then continue along the path while moving forward.
However, do note that the path to the item will be blocked. What you will need to do is to go down and head left. Just a little ahead of the gate that is blocking the path will be a cylindrical-shaped object hanging with a rope. You need to shoot the rope, and the path will then be opened. So, head up again and pick up the gear for the mechanism.
Activate The Mechanism

On the right side, ahead of the water, there will be an item that you need to make the mechanism on the north side work. So head to the northeast side, go up, and on the right, there will be a mechanism. To make the mechanism run, head to the platform on the other side of the water and move forward.
When you have to crouch to proceed, on the right side, you will find another item. You now need one more item to start the mechanism, which you should already have. So insert that into the mechanism and then head down. Go ahead and then head left to pull down the lever.
Upon doing so, the elevator will go up, and ahead of you will be the area where you can upgrade your weapons and save your progress.
Explore The Outer Rings Area

Then go ahead, take a left, then right, another right, left, right, and follow the path forward. When you see a slightly destroyed path on the right side, interact with the block to move forward. Then continue ahead, and eventually you will reach a dead end. When that happens, a cutscene will begin.
You will then find Marlene injured and many of the agents inside the area dead. So now you have to fight Walter.
Defeat Walter

As the fight starts, Walter will begin shooting at you, so head right where there will be a pipe bomb. Pick it up, and then when Walter finishes firing, close the distance between you and shoot the middle section with a shotgun. After a couple of solid hits, it should be stunned, and when that happens, shoot the orange part in the middle.
There will be bandages and ammo around, so make sure you pick those up. When Walter is stunned, its middle part opens up, so you can even throw a pipe bomb inside, which will deal significant damage. You need to stay in cover for most of the fight and wait for Walter to finish firing.
As soon as it finishes firing, use your shotgun to stun it and then deal damage. If you have more grenades or pipe bombs, use them when Walter is stunned.
Second Phase

Once you have dealt enough damage, Walter will stop using the gun, and a shield around the middle area of its body will appear. Then some monsters will join the fight, so take care of them. However, be aware that instead of firing, Walter will now use a laser.
Walter will point a laser at your position and set a target. Shortly after, a strong explosion will occur at that spot, so make sure you move away quickly. This phase will not end on its own, and the monsters will keep appearing. You may have already noticed that there are four pillars with the same shield as Walter.
You need to destroy the pillars, but you do not have the firepower to do so directly. So what you need to do is use Walter’s laser to destroy them. It is quite simple, as you just need to stand in front of a pillar and wait for Walter to lock on the target. When it is about to fire the laser, run away, and the pillar will be destroyed.
Do this four times, and this phase will be over. However, do not just stand near the pillars, as Walter can also perform melee attacks. When the last pillar is destroyed, Walter will go down. When that happens, talk to Marlene, who will be on the opposite side of where Walter has fallen.
Take Down Walter

When the conversation is over, Walter will get up again, so shoot the middle part. When the middle part opens, get close, and you will see the core. Shoot the core and repeat this process. Eventually, it will go down, and when that happens, approach it and interact with it. Then a cutscene will begin, and you will get a main choice to make.
Should You Destroy Atlas Or Spare It

This choice does not have much effect on the story, or at least, the game does not make a big deal out of it. Choose the option you prefer. Do note that upon destroying it, Nora will be sobbing on the ground, or at least, that is how it appears. However, if you spare Atlas, she will walk away.
So choose whichever option you want, and upon making the choice, Chapter 3, A Change of Plan, along with Industria 2, will conclude. With that, this walkthrough also comes to an end.
