Phase 2 of AIC Support: Chubby Lung Attacks opens on day 8 of the event and adds a second limited-time formula: Heavy Xiranite Chubby Lung, made at the Packaging Unit from Proto Chubby Lung Heavy Shells and Proto Xiran-Cuprium Frames. It trades at the Wuling outposts for more Wuling Stock Bills and Fruits of Altruism Certs than the Phase 1 Xiranite Chubby Lung does. This guide is the Phase 2 build: two main blueprints for the Yinglung Pass sub AIC, two helpers depending on where your base is, and two optional rush blueprints, all with Asia and NA/EU codes.

It sits on top of either the Part 11 Wuling 1.4 mega base or the Part 13 1.5 upgrade, and it picks up where the Part 14 Phase 1 build left off. You do not need to have run Phase 1 first. Each step below splits by which guide your base currently follows.

Quick Answer

Upgrade the Yinglung Pass sub AIC to its maximum size, then work through four areas. On Marker Stone, cut the top side down to its three Cuprium lines. On the Core AIC, leave only the Separator Core section running. Empty Yinglung Pass and deploy Event P2Top along the top edge with Event P2Bot right below it. Then feed it 80 Inergen and 84 Xiragen per minute. That makes 12 Heavy Xiranite Chubby Lung per minute, about 345,600 Fruits of Altruism Certs a day, which clears the whole Phase 2 shop in about 5.12 days, or 2.2 days if you skip the final T-Creds entry. All codes are region locked for Asia and NA/EU.

Requirements

  • The factory requirements of the 1.4 base or the 1.5 base, at minimum. Either works.
  • The maximum size upgrade on the Yinglung Pass sub AIC. The two Phase 2 blueprints fill it.
  • An Inergen conduit outlet carrying at least 80 per minute, which means four or more Gas Extractors feeding it.
  • A Xiragen outlet carrying at least 84 per minute. The 100 per minute North Wuling Exclusion Zone line from Part 11 covers it.
  • The Heavy Xiranite Chubby Lung formula unlocked in the event. It is a limited-time Phase 2 formula, so the factory cannot build it before the event hands it to you.

Heavy Xiranite Chubby Lung Blueprint Codes

Open Blueprints, go to Shared Blueprints, click Import Blueprints, and paste the code for your server region. Codes are region locked, so Asia and NA/EU are not interchangeable. If you are typing by hand, there is no letter L in any of these codes, the letter O and the digit 0 are different characters, and a stray space at either end will reject the import. The copy buttons avoid all three.

Everyone needs Event P2Top and Event P2Bot. Event Temp is only for players who deleted the Core AIC Separator Core section during Phase 1, and 1.5 MS Top is the same code as in Part 13, needed only if your Marker Stone is still on the 1.4 layout. Event ExXir and Event P1 Md are the rush set. Skip them unless the shop math says you are behind.

Step 1: Marker Stone Top

Go to the Marker Stone sub AIC. The target for this step is a top side that runs only its three Cuprium processing lines, and nothing else.

The target: three Cuprium lines and nothing else on the top side

How much work that takes depends on the guide you built from:

  • You followed the Part 14 Phase 1 guide. You already removed the Separator Core section. Nothing to do here.
  • You are on the Part 13 1.5 base. Delete the small section highlighted below. It is the Separator Core section, the same one Phase 1 removes.
  • You are still on the Part 11 1.4 base. This one takes three moves, covered after the picture.

From the 1.5 base: delete this Separator Core section

From the 1.4 base, first disconnect the Inergen conduits and move them away so the clear does not take them with it. Then remove everything on the top side, deploy 1.5 MS Top, and finish by deleting the same small Separator Core section.

Then delete the Separator Core section, same as the 1.5 route

Step 2: Core AIC Separator Core

On the Core AIC bottom side, the goal is the same whichever route you took: the Separator Core line running and everything else stopped. There are two ways to arrive there.

If you followed the Phase 1 guide

During Phase 1 you either turned this whole area off or removed it.

The area Phase 1 switched off or removed

Now turn back on just the small section making two lines of Separator Core. If you deleted the area instead of switching it off, deploy Event Temp there and plug an Inergen conduit outlet into it. That is the outlet Phase 1 told you to move aside rather than delete.

Turn this Separator Core section back on, or deploy Event Temp and plug the Inergen outlet in at the bottom

If you skipped the Phase 1 guide

Your bottom side is still the full build from the 1.4 or 1.5 guide. Turn off everything highlighted here and leave the Separator Core line alone. All you need from this side is its 60 per minute Separator Core.

Turn off the highlighted sections, keep the Separator Core line on the left running

Step 3: Empty Yinglung Pass

Everything inside the Yinglung Pass sub AIC gets deleted. Before you do that, move your resource conduits out. These are the conduit outlets wired straight to the inlets that bring in raw resources: Inergen, Xiragen, clean water and acid. Park them outside the area first and you cannot delete them by accident and end up running the source again. The Phase 1 guide shows the same parking move with pictures.

Then empty the sub AIC and move the core to the bottom left for now, out of the way of the first placement.

Step 4: Deploy P2Top and P2Bot

Deploy Event P2Top along the topmost edge of the sub AIC.

Event P2Top goes on the topmost side

Move the core up to the top side, turned so it takes items horizontally, sitting between the two Packaging Units. Then deploy Event P2Bot right below it, pushed toward the right side.

Step 5: Inergen and Xiragen

The build needs a conduit outlet carrying at least 80 Inergen per minute. That takes at least four Gas Extractors feeding one pipe. The Part 13 base only ran two, so add the extra extractors at the Inergen gas vent before you connect anything.

Move the 80 per minute outlet in to replace this one

Move that outlet into position so it replaces the one marked above. Then do the Xiragen. To be precise the build uses 84 per minute, but do not bother building to that number. Plug in the 100 per minute outlet that carries all the Xiragen collected from the North Wuling Exclusion Zone, which the Part 11 guide builds step by step. That completes the Phase 2 build.

Optional: Core AIC Cuprium Fix

One last change, and this one is worth keeping after the event ends. In the center of the Core AIC there are two Cuprium lines that end in Protocol Stashes. Remove those Protocol Stashes and route the items straight into the core with a small belt edit, like the pictures below. It does not have to be tile perfect.

Belt the Cuprium straight into the core instead

With the Cuprium going into the core, this section can never clog, so the battery line's supply is always guaranteed. That is true during the event and after it, which is why it stays. If your Protocol Stashes here look different from the picture, that is the Overflow Protector 2.0 edit, which put them there in the first place.

Production and Shop Math

At full speed the Phase 2 build makes 12 Heavy Xiranite Chubby Lung per minute, which is 720 an hour.

  • Stock Bills: all outposts together produce 141,360 Stock Bills an hour, and 12 per minute of Heavy Xiranite Chubby Lung is worth 144,000. The Phase 2 line covers the outposts on its own.
  • Certs: roughly 345,600 Fruits of Altruism Certs a day.
  • Trimmed event medal: it asks for 20,000 Heavy Xiranite Chubby Lungs submitted, which takes about 28 hours at this rate. The medal also wants 800,000 Certs earned across the event.
  • Leftovers: the build leaves 210 Cuprium and 30 Xiranite per minute unused. That is fine unless you are rushing.

The first three rows below are the shop totals from the event. The last two add the Phase 1 shop on top, for players arriving late, at the same 345,600 Certs a day.

GoalCerts neededDays at 12/min
Phase 2 shop, everything1,769,4005.12
Phase 2 shop, skip the final 100 T-Creds769,4002.2
Phase 1 shop, everything~411,000~1.2
Both shops, skip the final 100 T-Creds~1,180,400~3.4
Both shops, everything~2,180,400~6.3

The final 100 T-Creds entry is the expensive one: it alone accounts for 1,000,000 of the Phase 2 total. Everything else in the Phase 2 shop fits in a little over two days. The event runs until September 30 at 16:00 server time and the Goods Exchange stays open until October 7 at 04:00, so check your own Cert balance against the table and decide which shop lines actually matter to you.

Chill or Rush

If you are chill. You already emptied the Phase 1 shop and deployed the Phase 2 build early. Leave the base exactly as it is and let it run. The two-day figure for the Phase 2 shop, or five days with the T-Creds, is comfortably inside the event window.

If you are in a rush. You are late, usually because you skipped Phase 1. Run the numbers from the table against the time you have left. If you cannot clear the items you want before the event ends, put the leftover 210 Cuprium and 30 Xiranite per minute to work making extra Chubby Lung with the two rush blueprints, Event ExXir and Event P1 Md. Event P1 Md is the same modular block from the Phase 1 guide (each copy eats 120 Cuprium and 60 Xiranite per minute), and the rush setup uses the two blueprints together. This part is only for players who need to catch up. If the table already says you are fine, skip it.

Producing more than your outposts can take will eventually back the line up. The Part 12 overflow protector and the Phase 1 overproduction notes cover both the automatic and the manual fix, and they apply the same way to Heavy Xiranite Chubby Lung.

When the event ends, the factory restore guide puts the base back on the 1.5 layout step by step.

Frequently Asked Questions

Do I need to have run the Phase 1 build first?

No. The Phase 2 blueprints work on top of the Part 11 Wuling 1.4 base or the Part 13 1.5 base, whether or not you ever deployed the Phase 1 build. Every step on this page splits by which guide your base currently follows, so pick the branch that matches what you see in game. If you skipped Phase 1 entirely, run the shop math before you settle in, because you are the player the rush section is written for.

Can I use NA/EU codes on Asia servers?

No. Blueprint codes are region locked, so an Asia code will not import on NA/EU and an NA/EU code will not import on Asia. Both columns in the table describe the same layouts, they are just published per region. There is no letter L in any of these codes, and the letter O and the digit 0 are not interchangeable, so use the copy buttons if you can.

How much Inergen and Xiragen does Phase 2 need?

At least 80 Inergen per minute, which takes a minimum of four Gas Extractors feeding one conduit, twice what the Part 13 base runs. Xiragen is 84 per minute to be exact, but the simple answer is to plug in the 100 per minute outlet that carries all the Xiragen from the North Wuling Exclusion Zone, which Part 11 builds step by step.

How long does it take to empty the Phase 2 shop?

At 12 Heavy Xiranite Chubby Lung per minute you earn roughly 345,600 Fruits of Altruism Certs a day. The full Phase 2 shop costs 1,769,400 Certs, which is about 5.12 days. The final 100 T-Creds entry alone accounts for 1,000,000 of that, so if you skip it the rest of the shop is 769,400 Certs, or about 2.2 days. The Phase 1 shop is around 411,000 Certs on top.

How long does the trimmed event medal take?

The trimmed version of the event medal asks you to submit 20,000 Heavy Xiranite Chubby Lungs and earn 800,000 Fruits of Altruism Certs during the event. At 12 per minute, the 20,000 submission takes about 28 hours of production.

Is Event P1 Md the same blueprint as in the Phase 1 guide?

Yes. It is the Phase 1 modular block from Part 14, listed again here because the rush setup uses it. The Asia code is unchanged. The NA/EU code shown here is the current one, and the Part 14 table carries the same code.

Should I keep the Core AIC Protocol Stash change after the event?

Yes. Routing the two center Cuprium lines straight into the core instead of through Protocol Stashes is a permanent improvement, not an event hack. That section can no longer clog, so the battery line's Cuprium supply is always guaranteed. Leave it in place when you restore the rest of the base.

How do I put my base back after the event?

Reverse the steps. On Marker Stone, re-import 1.5 MS Top from the Part 13 guide to rebuild the Separator Core section you removed. On the Core AIC, turn the bottom side machines you switched off back on. On Yinglung Pass, clear the event blueprints and re-deploy your Part 13 or Part 11 Yinglung Pass blueprints, then pick up the resource conduits you parked outside. Keep the Core AIC Cuprium change, it is worth having either way. Part 16 of the series, Restore Factory After Chubby Lung Attacks, walks through every step with the codes.
