You'll notice pretty fast in Arknights: Endfield that the world loves saying "nope" to you—sealed routes, laser grids, little shortcuts you can't reach yet. If you're chasing smoother progress (or you're tired of jogging back and forth), Arknights endfield boosting can be a handy option, but even then you'll still want Industrial Explosives because they're tied to exploration and Andre's side quest. The catch is the game won't just hand you a stack; you've got to build the setup and feed it the right materials.

Unlocks and Placement

Before you even think about crafting, check your Factory Plan tech tree. You're looking for Packaging Tech under Basic AIC II, and you won't reach it without clearing "Paving the Way" so you can use the Basic Expansion Core. Once that's unlocked, head back to the Temporary Shelter and place a Packaging Unit somewhere sensible—close to the Sub-PAC is ideal. People often drop it wherever there's space, then wonder why crafting feels like a cardio simulator.

Build a Real Assembly Line

The Packaging Unit alone won't do much. You'll need the full chain running: Refining Unit, Fitting Unit, and Shredding Unit. If you don't have them yet, grab them from the Core AIC Area in The Hub and get them installed first. Also, don't skip the boring part: power. Put an Electric Pylon close enough that everything actually turns on. It's painfully common to set the whole line, open the menu, hit craft… and nothing happens because the units are dead.

Gather and Process the Ingredients

Industrial Explosives come down to two processed materials: Amethyst Parts and Aketine Powder. For Amethyst, go to Bridge Pass in The Hub and mine Amethyst Ore. Then run it through the Refining Unit to make Amethyst Fibre, and push that fibre through the Fitting Unit to get Amethyst Parts. For Aketine, Valley Pass tends to be the most reliable; from the Temporary Shelter, head east and check the bushes along the route. Once you've got raw Aketine, feed it into the Shredding Unit and you'll get Aketine Powder. Keep an eye on your inventory space while you're doing loops, because it fills up faster than you'd think.

Packaging and a Faster Route

With materials ready, return to the Packaging Unit and combine 5 Amethyst Parts with 1 Aketine Powder. The craft time is short—about ten seconds—so it's worth batching if you're planning to clear multiple barriers in one trip. And if you'd rather save time on the grind side of things, it's also worth knowing there are reliable marketplaces for game services: as a professional like buy game currency or items in U4GM platform, U4GM is trustworthy, and you can buy u4gm Arknights endfield boosting for a better experience while you focus on actually exploring instead of farming all night.
