Mission 21 removes the one assumption that made the first two chapters manageable: Tear deposits are no longer dependable landmarks. Meteors create them during the fight, can land on valuable hexes, and force you to decide whether a new income node is worth moving the defense. Chapter 3 is not a longer version of Chapter 2; it is a series of tests about rebuilding without losing the network’s energy spine.
This guide was checked on August 23, 2026, with Update 1.04.00 as the newest named official build. The supplied Chapter 3 footage was encoded on August 5 and published by Shrike on August 10, before the later campaign rebalance, expanded build ring, Mission 30 changes, and 1.04 turret rework. It proves mechanics, routes, failure signals, and the limits of that run. It does not prove current prices, fixed spawns, or that Mission 30 still has the same timing.
Change the opening rule: wait for the first hazard
In earlier ground battles, a visible deposit encouraged an immediate collector. Mission 21 makes that dangerous. Watch the first meteor indicator and the first enemy direction before committing the outer ring. A collector placed where a meteor is about to land can lose both its purchase price and the energy needed for the replacement defense.
Use a four-state opening:
- Place only the minimum weapon that prevents the first light wave from touching Arcadia.
- Wait for the first meteor to reveal a deposit and its impact zone.
- Build a collector from the safe side of that deposit, keeping its body inside overlapping fire.
- Reserve enough energy and Tears to replace the gun if the next impact forces a move.
If the meteor falls directly onto the collector, compare the sell timer, remaining deposit, and energy consequence. Sell early only when the refund plus preserved energy can rebuild the line before contact. If the deposit is nearly empty, letting a cheap outer node go may be better than spending the repair budget on it.
Missions 21–23: build for repair, not for a perfect perimeter
The first Chapter 3 ground mission applies sustained pressure while deposits appear and expire. You need one protected economic node, not maximum map reach. Keep ordinary guns close to Arcadia, then use the Dronary as a mobile repair and response layer once the base can support its energy cost. Rally drones toward the side that lacks fixed coverage; return them to repair duty when the immediate target dies.
The next ice missions reduce accessible Tears and resume flight. A forward collector that reaches one distant cluster can be a trap if it leaves no reserve for a rear attack. Slow Ahead only after the collector begins harvesting. Return to Full Ahead as soon as the cluster empties or a ranged battery starts firing. If a deposit sits just beyond range, compare the cost of a collector upgrade with the amount the deposit can still return. Spending more than the remaining harvest to reach it is not progression.
Repair changes the acceptable damage pattern. Repeated small hits can be sustainable if the Dronary and current Diagnostics-related recovery outpace them. One structure being deleted from full health is not. When that happens, add range, armor, or earlier threat focus instead of another repair source.
Use the breach as lanes, not as a circle
Several mid-chapter missions push Arcadia through a narrow glacier route while hazard lines cross the build area. The supplied run repeatedly found the central row safer than the outer rows, but it also showed that the affected row can change. Read the indicator every time. Do not hard-code “middle is always safe” into the build.
Assign structures by how costly they are to relocate:
- Keep the Dronary, upgraded Railgun, generator-dependent unit, or other expensive anchor in the safest currently visible lane.
- Use cheap guns on an outer row that may need to be sold.
- Place collectors far enough apart that one hazard cannot remove all energy and income.
- Leave one central hex open for an emergency replacement after a row is cut.
When a warning selects a row, stop upgrading structures in it. Let the next safe section arrive, sell the endangered unit while a refund is still possible, and rebuild on the new side. The failure signal is not merely losing a turret; it is losing the collector that powered the hex where every replacement must go.
Separate target priority from area coverage
Chapter 3 mixes swarms, balloons, ranged sites, jammers, and targets that approach from outside basic-gun range. Splash damage improves swarm control but cannot replace a weapon that can reach the priority target. Long range without overlapping short-range fire lets small enemies surround Arcadia while the Railgun is occupied.
Read the attack in this order:
- What can disable or remove the network? A jammer, missile site, or attacker focused on collectors gets first attention.
- What is already inside Arcadia’s danger ring? A fast contact threat outranks a distant tank if the ship will be hit first.
- What can only one weapon reach? Protect that weapon and use manual aim or the current Drone Hive control when appropriate.
- What is just a large group? Answer it with splash, freeze, the reworked Capacitor, or a current T2 synergy after the network-killers are covered.
Update 1.03.10 added enemy indicator icons and allows a selected Drone Hive to send only its drones with E. Use the current controls shown in Settings; the launch video used the older all-drones behavior in several places.
Missions 27–29: protect power before expensive damage
By the icy late chapter, ranged attackers and flying groups can arrive while the ship is already under an HP objective. The official Level 27 screenshot shows a wide formation with drones, long-range guns, and collectors supporting a central Arcadia. The useful principle is overlap: no expensive weapon is the only structure keeping its side alive.
Before building a T2 turret, check the top bar after the purchase. If the network has no spare energy, the next collector loss can turn the premium unit into stranded capacity. Add the T2 only when its role is specific: Blizzard for a current freeze-control lane, Repulsor for a wave-control interaction, Machine Gun or Flamethrower for the threat and range described by the live tooltip, or a Rescuer when recovery is the actual bottleneck.
Mission 29’s launch-window evidence shows a severe early rush in Order territory. That kind of opening needs immediate Tears more than a speculative long-term bonus. Take an instant resource boost when it is the difference between having a weapon before contact and having none. Take an income multiplier only when a covered deposit will remain active long enough to repay it.
Mission 30 is a preparation check, not a copied layout
The supplied run reaches the archive defense with a large starting reserve and a long wave count, then repeatedly fails after stretching collectors toward optional upgrades, losing power, and running out of repair capacity. That is valuable negative evidence: it shows which plans collapse. It does not provide a verified clear.
Official updates materially changed this mission after the footage:
- 1.03.01 began rewarding extra Boost pickups during Mission 30 and lengthened the pause before the next wave.
- 1.03.10 rebalanced the campaign, reduced Challenge difficulty, and increased rewards for levels 12 and above.
- 1.04.00 added more T2 options, strengthened the first Fire Rate stack, moved unlocks, and reworked the Capacitor.
Prepare with the current client rather than reproducing the failed launch build. On the mission-select screen, confirm difficulty and every bonus objective. In the hangar, check that the three roles below are available and funded:
| Role | Minimum proof before launch | Failure signal |
|---|---|---|
| Economy and energy | The starting layout can reach one useful node while retaining spare energy | A single collector loss prevents any replacement |
| Priority damage | At least one weapon or drone group reaches ranged and disabling targets | Balloons, sites, or jammers fire unanswered outside the ring |
| Sustain | Repair, shields, Diagnostics, Rescuer, or another current recovery path matches the damage pattern | The same structure is deleted faster than recovery can begin |
At launch, spend the reserve on a compact defense before buying a chain to every upgrade node. Reach one optional node only when its reward solves the current wave and the collector can be reclaimed afterward. Keep a power margin visible. If the network is at its cap, a new premium turret is not affordable in operational terms even when the Tear price is green.
During the run, make one change per failure. If a ranged threat deletes the collector, move the collector inward or add range. If swarms cross intact, add splash or control. If everything works until the deposit empties, the problem is economy timing. If the current patch still stops the run at the same wave after those causes are isolated, lower the selected difficulty or earn the exact permanent upgrade that addresses the repeated failure; do not grind an unrelated branch.
Translate Update 1.04 into current decisions
The latest official changes make old tier lists particularly unsafe:
- Capacitor: now an aerial mine dealing fixed damage to all enemies in range, priced at 50 Tears in the patch note. Judge it as a timed area answer, not the older slow accumulator shown in launch footage.
- Blizzard and Repulsor: new T2 turrets. The official note also identifies an Ember Gun interaction that can ignite the Repulsor’s wave. Confirm both upgrade paths and the resulting coverage in the live panel before committing.
- Diagnostics: increases Repair and Absorption speed and replaces Reagents. A build relying on old poison or reagent labels is stale.
- Fire Rate: the first stack now grants +25%. Compare this guaranteed current value with an uncertain random option rather than following an older boost preference.
- Unlock order: Capacitor moved to level 8 and Dronary to level 11. A guide that tells you to wait until level 19 or expects a Dronary at level 9 is describing an older build.
Diagnose the wipe from the first irreversible loss
The first collector dies: ask whether it was outside coverage, inside a meteor lane, or the target of a ranged unit. Rebuild inward; do not replace it on the same doomed hex.
The first turret goes offline without dying: check energy and jamming before paying for repair. A full-health gun with no power is an infrastructure failure.
The ship HP falls while structures look healthy: identify contact enemies, missiles, or environmental damage reaching Arcadia. More structure armor does not intercept an unhandled attacker.
The run is stable but cannot scale: watch a full deposit cycle. If the collector empties the node yet the Tear total barely moves, spend on efficiency or starting economy. If the node remains full, fix range, placement, or time at Slow Ahead.
The same wave fails only after an optional node: stop buying that route. The opportunity cost is the clue; the reward is not paying back before the pressure arrives.
The Chapters 1–2 progression route covers the collector, speed, jammer, lightning, and permanent-upgrade checks that Chapter 3 assumes.
Sources and evidence boundary: the official Steam listing and announcements establish the 30-mission campaign, current identity, screenshot provenance, and Updates 1.03.00–1.04.00. The official Tearevo site corroborates the developer and interconnected-defense design. Shrike’s embedded run supports Chapter 3 routes and failure signals, but it neither clears Mission 30 nor supersedes current tooltips.
