Summary of "Arknights Endfield - All Main Story Quest (Version 1.0) Chapter 1 & 2 (Complete Playthrough)"

Arknights: Endfield — Chapters 1–2 (v1.0)

Storyline (main beats)

You awaken as the Administrator / “Endman” aboard the originium-powered ship D’Jang with severe amnesia. Supervisor Plica (Pearlica) and Enfield Industries staff (Operator Chen, Mr. Andre “Big Owl”, Director Chin, etc.) take you in.
Valley 4 hub base is attacked: orbital anchorfalls spawn angaloy, communications go dark, and coordinated landbreaker raids (Bone Crushers clan and others) sabotage facilities and steal prototype parts.
Enfield’s objective is to stabilize and restart local infrastructure using the Protocol Automation Core (PAC) / Automated Industry Complex (AIC), rescue survivors, clear anchors/angaloy, recover stolen prototype parts, and restore power.
You lead field operations: clearing anchors/angaloy, rescuing civilians, rebuilding the PAC/AIC factory, producing originium materials and equipment, and escorting/repairing the experimental prototype “Tata.”
A large-scale antagonist emerges: Nefareth/Neferith (leader of the Bone Crushers) uses ether/blight tactics, awakens an Angalos-like giant (the Great Oak/Angalos amalgamation), and pushes for an ether rift at the Power Plateau.
Tata (the prototype) is deployed and ultimately seals the rift at the Power Plateau (sacrificially), allowing Enfield and UWST allies to stabilize the region.
The chapters end with Valley 4 recovering and the larger threat (ether rifts / Neferith) set to move north — Wooling City (Wuing) becomes the next focus, and the Zeroth Directive / PAC deployment agenda expands.

Gameplay highlights, systems, and in-field strategies

Base / facility gameplay and logistics

Protocol Automation Core (PAC) / Automated Industry Complex (AIC)
- Deploy PAC to create relay towers, produce refined materials, and automake facilities (shredders, refiners, pumps, turrets, outposts).
- Craft key components such as Origo crusts, amethyst parts, and Shironite.
Relay towers & resonance towers
- Place relay towers to transmit PAC power and force-start resonance towers to re-power base systems.
Sub-PAC / outpost
- Deploy sub-PACs to establish forward outposts that pull resources from the depot and allow local facility/defense production.
Portable originium autominer
- Place on ore nodes to auto-harvest arigium (self-powered).
Shredder / originium powder
- Produce demolition explosives and materials to clear rubble (landslide / power-plant entrances).
Forge of the Sky / Shironite production
- Use the AIC to produce Shironite and restore/reactivate Tian/Shironite arrays in Wooling.

Combat & field tactics

Anchors are the primary objective: destroy the anchor’s stabilizing core to stop spawning angaloy. The core is fragile but heavily guarded.
Crowd control focus: eliminate angaloy swarms (the minions) before targeting the anchor core. Use concentrated attacks and coordinated team strikes.
Use incendiary weapons and explosives to break dense haze and destroy landbreaker furnaces (dance tanks) that generate blight haze.
With large or multi-part enemies (e.g., Angalos remnant), target appendages or minion spawns first, then the main body. Avoid shockwaves; use originium branches/saplings where available to block or nullify shock pulses.
Use TP (teleprotocol) points for fast traversal and coordinate with UWST allies and specialists (Wolfgard, Ivonne, Fabian/Alisa Collins, etc.).

Special systems / tools to leverage

PAC deployment checklist
- Verify PAC authorization (administrator-only), place PAC in AIC core area, deploy relay towers, then power the resonance tower to restore base functions.
AIC production loop
- Gather arigium ore → refine into Origo crusts → produce parts (amethyst, stabilizers) → build facilities (refiners, shredders, autominers).
Signal towers + Tata prototype
- Connect Tata to ProtoCom signal towers to scan for blight cores; linking multiple towers reduces noise and improves scan effectiveness.
Data loggers / protocol data loggers
- Gather AIC index points to unlock new AIC tech upgrades (better mining rake, parts fitting, expansion cores).
Defensive facilities
- Deploy gun towers / combat facilities at chokepoints to defend outposts and hold supply lines while crews repair or build.

Step-by-step workflows (quick reference)

Restore a damaged hub base (high level)
1. Secure survivors and route them to safe shelters (control tower).
2. Clear immediate angaloy and destroy anchor cores (stop spawning).
3. Deploy PAC, then place relay towers to transmit power to the resonance tower.
4. Use AIC to produce Origo crusts and repair critical facilities (comm node, processing center).
5. Deploy outpost/sub-PAC to maintain forward operations.
Using Tata to locate and neutralize blight cores
1. Repair/prepare Tata (prototype) at the research lab (Ivonne’s help).
2. Connect Tata to a nearby ProtoCom signal tower (use at least two towers for lower noise).
3. Run scans to reveal blight cores; avoid repeated overheats and optimize scan positions to detect multiple cores at once.
4. Physically attack and destroy the exposed blight cores (prototype assists but direct action is required).
5. Park Tata at a safe location after scan, or send logs back to research for further tuning.
Producing Shironite (Wooling)
1. Deploy AIC “Forge of the Sky” module in the designated plot.
2. Feed basic raw materials (local ore) into the Forge and produce test batches of Shironite.
3. Inject Shironite into flow-control nodes to restart monitoring arrays and purge blight zones.
4. Scale up production once parameters are validated.

Key tips & cautions

Prioritize protecting the comms node and resonance tower; without communications/power, coordinating reinforcements is very hard.
Anchors often bury their core; look for underground access (basements/mines) and be prepared to fight belowground.
Always defeat angaloy swarms before focusing the core; otherwise the spawn will overwhelm you while you attack the core.
Use autominers and PAC production to reduce manual gathering — the AIC is intended to rapidly scale supplies.
Monitor prototype (Tata) heat/overload — scans can overheat the unit; repairs by Ivonne (or Andre) may be required.
Turrets and gun towers at chokepoints make defending outposts much easier and buy time to clear blight and anchors.
Keep a backup plan for landslides / rubble — explosives or shredders (AIC-built) can open blocked roads when heavy machinery is unavailable.
Beware the ether/blight interplay — blight zones can disable originium devices and complicate aerial support.
