What to know
- Explosive Bombs come from the “Produce Industrial Explosives” exploration mission chain.
- The mission starts after receiving Andre’s message and progressing far enough in the main story to access that step.
- Crafting requires unlocking the Packaging tech/unit, then producing the required intermediate materials.
- After crafting, bombs must be placed into the backpack and selected on the Easy Tool wheel to use them in the field.
In Arknights: Endfield, Explosive Bombs are a utility item unlocked via an exploration mission and then produced through the factory chain, letting blocked paths and destructible obstacles be cleared during exploration objectives.
Reference table for prerequisites and where they apply
| Goal | What to complete / do | Where it matters |
|---|---|---|
| Unlock Etchspace Salvage mode | Reach Authority Level 25, progress to Chapter 1 – Process 3, then complete the Etchspace Salvage quest. | Unlocks Etchspace Salvage access so commissions like Aberrant Exploration can be attempted. |
| Unlock Explosive Bombs (Industrial Explosives) | Complete the “Produce Industrial Explosives” exploration mission chain. | Enables crafting and using the Bomb utility needed for destructible obstacles. |
| Equip bombs for use | Place Industrial Explosives into the backpack and switch to Bomb on the Easy Tool utility wheel. | Required to actually throw/use bombs in missions and exploration. |
Factory chain quick reference
| Part of the chain | What it does | Why it matters |
|---|---|---|
| Packaging tech / Packaging Unit | Unlocks the production path tied to explosives. | Without it, Industrial Explosives cannot be produced. |
| Aketine → powder step | Converts Aketine into the form used by the explosives recipe (commonly via shredding). | This is a frequent bottleneck if supply is low. |
| Amethyst processing → parts | Converts mined ore into usable manufactured parts (often via refining then fitting). | Supplies the other major input for the explosives recipe. |
| Backpack + Easy Tool wheel | Lets the Bomb utility be equipped and used. | Crafting alone isn’t enough; it must be equipped. |
Suggested final checklist before starting “Aberrant Exploration”
- Confirm the Produce Industrial Explosives quest is completed and Bomb is available on the utility wheel.
- Craft a buffer of bombs so the run doesn’t stall on destructible gates.
- Ensure bombs are in the backpack and actively selected before entering the mission area.
How to unlock Explosive Bombs in Aberrant Exploration
Step 1
Unlock and enter Etchspace Salvage, then pick the Aberrant Exploration commission before starting the run.
Step 2
Follow the Aberrant Exploration objective route through the zone while keeping Derangement Acceleration under control (the longer the run goes, the risk ramps up).
Step 3
Reach the boss-gated section tied to the commission’s progression and initiate the boss fight (boss encounters can block access to key loot/progression points).
Step 4
Defeat the boss to trigger the commission progression and the unlock event for Explosive Bombs shown in the video’s completion flow.
Step 5
Continue the run long enough to confirm the unlock is active/available during the run (or in the post-run results), then extract to bank the run’s progress and rewards.
How to handle the boss fight cleanly in Etchspace Salvage
Boss fights in Salvage commonly punish slow play because the mode’s risk meter keeps climbing, so the goal is to stabilize quickly and avoid unnecessary detours before engaging. A practical approach is to enter the boss room with cooldowns ready, focus on stagger/down windows, and prioritize survival over greedy damage so the run doesn’t collapse late.

Finishing notes for Explosive Bombs and Aberrant Exploration
If bombs are unlocked but not usable, the most common cause is forgetting to place them into the backpack or not switching the Easy Tool to Bomb before attempting to interact with destructible obstacles.
