Unlocking the Bunker

You will visit the Bunker for the first time after completing the prologue. You can return to this place later in the game. Because of its location, the only way to reach it is via fast travel - you must reach any Access Point on the main map and select Transport.

Improving Communications

Quest giver: Commander (Bunker)

This mission is easy to miss because it starts in the Bunker - the main story doesn't require you to go back there. You can start the quest in chapters 2, 3, or 4 of Route A. Visit the Resistance Camp, interact with the Access Point, select Transport, and move to the Bunker.

When you get there, go to the command center and talk to Commander.

Quest description: Return to the surface and await word from command. Your goal is to obtain several common crafting materials - Rusty Bolt x1, Small Gear x1 and Broken Key x1. It is possible that you already have them - obtained either as rewards from quests or found during exploration. Otherwise, visit the quest area in the City Ruins.

After obtaining the items, go to Anemone at Resistance Camp to end the mission.

Rewards for completing the quest:

1. Simple Gadget x5
2. Medium Recovery x3
3. 3,000G
4. 320XP

11B's Memento

Quest giver: YorHa Soldier / 16D (Bunker)

This mission is easy to miss because it starts in the Bunker - the main story doesn't require you to go back there. You can do this quest only in Route A. Try to start it in chapter 2, 3 or 4. Visit the Resistance Camp, interact with the Access Point, select Transport, and move to the Bunker.

In the bunker, get to the hangar. This should trigger a conversation with a YoRHa soldier, 16D. Agree to help find 11B.

To search for 11B, you must go to the Abandoned Factory - you have to go deep into that location. The goal is to reach the metal balconies around the large silos. In the place from the picture, you will be able to go down the screen and jump on the red crane.

Explore the area and get to the destroyed walls of one of the buildings.

11B's corpse can be found in the place from the above images. Interact with them to unlock 11B's Escape Plan and obtain 11B's Belongings.

You can leave the factory, go back to the Resistance Camp and use the transport option to get back to the Bunker. Talk to 16D. You can reveal the truth that android 11B was planning desertion, or you can lie - this will not affect the quest's finale or the rewards.

Rewards for completing the quest:

1. YoRHa-issue Blade - a unique melee weapon.
2. Ranged Defense Up (L) x1
3. Melee Defense Up (L) x1
4. Melee Defense 6 Chip - a great chip that increases the hero's resistance to melee attacks
5. 5,000G
6. 200XP

YoRHa Betrayers

Quest giver: Access Point (Bunker)

In chapter 6, you should receive an email Operator 6O: Confidential Mission Details. Reading it will add a new quest. It's about finding the YoRHa deserters.

Quest description: Move to the City Ruins. There are 3 red circles on the map - they mark where the wanted androids can be found. In our case, the androids were in the largest circle - the roof of the building that can be accessed by following the stairs and jumping through holes in the ceilings. If there are no androids there, go to the area next to the Abandoned Factory - check out the area under the damaged bridge.

You will face androids 22B and 64B. It is worth noting that they are much more agile and better at close-quarters combat than the machines. Use perfect dodges, or use Pod's ranged attacks. The weakened androids will escape.

You will find them again in the red circle marking the defeated Goliath. You have to climb to the very top of the inactive Goliath - use metal balconies and the ladders.

On the Goliath's highest platform, you will encounter 22B and 64B. Defeat them once more. Keep fighting until a stronger android, 8B, will appear. The former android-captain will be a little more difficult - this opponent has more health and higher resistance. However, the general tactics do not change - dodge a lot and use ranged attacks.

After winning the fight, get to the Resistance Camp and talk about deserters with Anemone. The quest ends when you receive a call from the command.

Rewards for completing the quest:

1. Type-4O Lance unique weapon
2. 10,000G
3. 400XP

Mysterious Letter (DLC)

Quest giver: Access Point (Bunker)

You must install the 3C3C1D119440927 DLC. You need to buy it separately if you have the basic version of NieR Automata. The DLC comes with the Game of the YoRHa Edition. Even if you bought the GotY edition, you will probably need to install this DLC separately. We described this in more detail on the page Game of the Yorha Edition in the appendix to our guide.

If you have installed the DLC, you will receive the following email from an anonymous sender in chapter 6. It will contain 3 sets of coordinates and the described quest will appear in your journal. By visiting locations from the coordinates, you will discover 3 more quests:

2. Gambler's Colosseum - Go to the page with descriptions of quests from Flooded City.
3. Underground Colosseum - Go to the page with descriptions of quests from Forest Zone. Only 9S can complete this task, so you'll have to wait until youreach Route B.

Data Analysis Freak

Quest giver: Operator 21O (Bunker). The quest is only available in Route B.

You'll need to advance to chapter 6 in Route B. When you go back to the Bunker to report on your last mission, reach the upper balcony of the command center. In the place marked in the picture, you will find one of the operators - this is the quest giver.

Quest description: Examine the terminal in the Abandoned Factory. Use fast travel to get near the entrance to the Factory and start exploring it. The area you have to examine was marked on the above image - it is one of the larger rooms where the camera switches to top-down perspective.

To transmit the collected data, you need to go to the surface - leave the factory building and wait for 9S to contact the Operator. Visit any Access Point to receive an email with rewards for completing the task.

2. Medium Recovery x2
3. 3,000G
