All 4 IRON NEST Endings in White Shells
How to get all four endings
Find all four endings in White Shells: three observed Barcelona shell routes and a reported betrayal combat route for The Road Not Taken. Use the table for exact ammunition, then open a named route for completion signals and failure checks.
All IRON NEST endings at a glance
| Named achievement | Narrow route supported by the available evidence | Outcome | Evidence |
|---|---|---|---|
A City in Celebration | Fire a PRPG shell at Barcelona | Barcelona celebrates and welcomes peace | OBSERVED · one complete PRPG chain plus one independent outcome |
A City Subdued | Fire CYAN or WP at Barcelona | Barcelona is subdued and order is restored | OBSERVED · one CYAN chain plus one WP chain |
A City Silent | Fire ATMC at Barcelona | Barcelona is left silent and destroyed | OBSERVED · two ATMC chains |
The Road Not Taken | Attack High Command, then remove the artillery that retaliates against Iron Nest | The General dies and Barcelona is spared | OBSERVED outcome · REPORTED combat route |
Unless a section says otherwise, OBSERVED footage on this page was reviewed on August 14, 2026 and does not display a build number. The label does not mean the route was reproduced on Patch #4.
A City in Celebration
Trigger
Fire a PRPG shell at Barcelona. In the reviewed Levas footage, the ammunition card visibly shows PRPG, the shell is fired at the city, the teleprinter describes bells and an era of unity and peace, and the White Shells result records one shot with no kills. See the PRPG card, the result message, and the result statistics.
TimHawk's separate video shows the same Celebration result text and newspaper outcome, although the reviewed segment does not provide a readable PRPG load. See the independent Celebration result.
What to expect
The result text describes Barcelona celebrating and welcoming peace. Use A City in Celebration as the canonical outcome name even if another video calls this Ending 1, 2, or 3.
If it did not trigger
- Check that the loaded shell was actually
PRPG, not another smoke, illumination, or non-lethal-looking shell. - Check that the shot was directed at Barcelona, not High Command or a battlefield target.
- Wait for the finale result instead of judging the route only from the impact effect.
- If the same action behaves differently, record the visible build and original evidence.
REPORTED variant: one third-party guide describes a broader “non-lethal” category. The reviewed footage does not show other shells producing this result, so the main route recommends only PRPG.
A City Subdued
Triggers
Two specific shells produced the Subdued outcome in two different release-version videos:
CYAN: Levas shows theCYAN SHELLpurchase and later theBARCELONA SUBDUED / ORDER RESTOREDnewspaper. See the CYAN shell and the Subdued result.WP: TimHawk shows both gun controls set toWPand later the same Subdued newspaper outcome. See the WP load and the Subdued result.
What to expect
The result identifies Barcelona as subdued and says order was restored. The footage supports CYAN and WP individually; it does not establish a universal chemical-shell class rule.
If it did not trigger
- Use one of the two observed shells rather than an unverified substitute.
- Verify the shell shown on the physical gun control before firing.
- Confirm that Barcelona—not High Command—was the target.
- Do not assume Nerve Agent or every chemical-type shell is equivalent. Other variants appear in guide claims, not in the reviewed trigger footage.
Scope: only CYAN and WP have direct video chains in the reviewed evidence.
A City Silent
Trigger
Fire ATMC at Barcelona. This is the strongest observed city-shell route in the current evidence set:
- Levas shows an
ATMC SHELLand later the Barcelona Silent newspaper. See the ATMC shell and the Silent result. - TimHawk independently shows
Shell Type ATMCarmed and later the same Silent outcome. See the armed ATMC load and the independent Silent result.
What to expect
The newspaper describes Barcelona as silent and flattened. The official outcome name is A City Silent; the videos do not show the achievement pop-up, but they independently connect ATMC with the same finale result.
If it did not trigger
- Confirm that
ATMCis shown on the loaded gun and that the shell is armed. - Confirm that the firing solution targets Barcelona.
- Check the teleprinter and newspaper before treating the lack of an achievement notification as a failed route.
- Record the current build and result screen if the outcome differs.
The footage also shows a requisition price in one run, but price and inventory are not part of this guide's trigger claim and may change independently.
The Road Not Taken: betrayal route
The Road Not Taken is not another shell choice for Barcelona. It is a betrayal route that turns Iron Nest against command, produces a TRAITOR state, and ends with the General dead and Barcelona spared.
Recommended route, with evidence limits
Two third-party guides and multiple community reports recommend this sequence:
- Prepare your firing information and enough resources for a follow-up fight before committing to betrayal.
- Attack High Command instead of firing at Barcelona.
- When the teleprinter reclassifies Iron Nest as hostile, read the new messages and locate the artillery that can retaliate.
- Destroy the active retaliation targets shown in your current operation.
- Continue until the finale result confirms that the General died and Barcelona was spared.
What to expect
The outcome is directly supported by two videos: Levas shows a TRAITOR message and later the city-spared newspaper, while TimHawk independently shows the same hostile state and result. See the Levas betrayal state, the Levas outcome, the TimHawk betrayal state, and the TimHawk outcome.
Route limit: the videos do not reveal a complete fixed target list, a universal number of retaliation guns, their spawn positions, or one mandatory reconnaissance method.
If The Road Not Taken did not trigger
You never received the TRAITOR message. REPORTED: the route sources point to High Command, not Barcelona. The reviewed videos do not show the first trigger as one complete sequence, so preserve any differing teleprinter response.
You attacked High Command but received no ending. Multiple non-official sources report that destroying High Command alone is not enough. Continue reading the new orders and remove the artillery that is actively returning fire against Iron Nest.
Reconnaissance looks clear but the fight continues. Use fresh information and inspect the current operation rather than copying a fixed target count. One Discord player reported that scout planes missed the last three or four guns and that Star Shells revealed them. That report has no build or video and does not prove the number is fixed or that Star Shell is mandatory.
You ran out of resources after betrayal. REPORTED: one guide recommends buying what you need in advance. Current public evidence does not establish a supply lock, exact inventory, or fixed cost, so treat preparation as a precaution rather than a rule.
The outcome appeared but the achievement did not. Separate the newspaper result from the Steam unlock. Capture the named outcome and visible build, then check the Pride of Castile note below if you are collecting every White Shells medal.
Can you get all four endings from one Campaign save?
Treat each named outcome as a separate finale attempt. REPORTED: two third-party guides say you can restart or replay the finale instead of repeating the entire Campaign. The reviewed public evidence does not continuously show the Patch #4 replay entry, state reset, supplies, map marks, or achievement persistence. Do not assume a reset worked until the current White Shells state is visibly fresh.
For a clear collection order, attempt the three direct city-shell outcomes first and the betrayal route last. That order is organizational, not a verified speedrun or resource rule.
Endings Checklist
Your own notes only. Checked boxes do not verify a game achievement or prove that a replay reset.
How many endings does IRON NEST have?
Steam lists four named Campaign outcome achievements. Its achievement page confirms the names, not the triggers. Chill mode is separate and is not a fifth Campaign ending.
Is there a secret fifth or Cannon Ending?
No fifth officially named Campaign outcome is supported by the current evidence. A short video calls a king-kill route a secret ending, but it lacks independent or official support. A separate video titled Cannon Ending never reaches White Shells and does not show a finale outcome.
Why Ending 2 and Ending 3 do not match every guide
There is no verified official numbering map. In the reviewed Google results, Ending 2 was variously assigned to the propaganda route, the ATMC/Silent route, and the Subdued route. Video chapters also use creator-defined orders.
Use the four Steam achievement names as the canonical labels:
- Want the celebration outcome? Follow
A City in Celebration. - Want the subdued outcome? Follow
A City Subdued. - Want the destroyed-city outcome? Follow
A City Silent. - Want the betrayal outcome? Follow
The Road Not Taken.
This avoids solving the wrong route when a search result calls it Ending 2 or Ending 3.
White Shells mission vs. ending choices
One continuous full-game recording shows White Shells as the final named Campaign operation. That is an observed sequence, not a developer-published Mission 15 number.
This page covers finale choices, named outcomes and failure checks. For the operation setup and combat walkthrough, use the separate White Shells mission guide.
Does Chill mode have an ending?
No—not as a fifth Campaign story ending. The official FAQ describes Chill mode as tracking cumulative confirmed kills across completed runs, while historical developer messages describe it as having no end, goal, or timer. Both place it outside the White Shells outcome set.
Those developer messages are from the pre-release period. Current public evidence does not establish a Version 1.0 procedure for leaving Chill mode, sleeping, receiving a newspaper, or settling a run. A dated community message describes a sleep-and-newspaper flow, but it does not show the current UI.
Why Pride of Castile may not unlock
Steam lists Pride of Castile as the achievement associated with earning gold medals in White Shells. Between August 9 and August 13, 2026, several players reported completing the four outcomes without receiving it.
As of this research check, no observed developer reply or patch note confirmed a bug, explained a root cause, or provided a universal fix. A community theory says the game may be checking mutually exclusive medals within one run, but that is speculation. If the achievement does not unlock, keep screenshots of the four named results and the visible build, then check newer official patch notes before repeating the full set.
