Game Guide by Ragib Rawnak on Feb 03, 2026

To get past laser beams or red-lined rocks when no barrels are around, you need to make your own Industrial Explosives. You have to play until you unlock the Packaging Tech in the second part of your tree. This lets you build a Packaging Unit to craft the bombs.

The Machines You Need

You need three different machines to get the job done. First, build a Fitting Unit to make the metal bits. Then, get a Shredding Unit to grind up plants.

Finally, use the Packaging Unit to put everything together. Make sure an Electric Pylon is close by so the machines have power in Arknights: Endfield.

Making Amethyst Parts

One part of the recipe is Amethyst Parts. To get these, take Amethyst Ore and refine it into Amethyst Fiber. Put that fiber into the Fitting Unit. It will turn the fiber into the parts you need. You can even use a Deposit Unloader to move these parts into your bomb maker automatically.

Finding and Grinding Aketine

The other ingredient is Aketine Powder. You get this from a plant called Aketine. Look for bushes in the Valley Pass area near the Temporary Shelter. Head east down the path to find them. Once you pick the plants, put them in the Shredding Unit. It turns the leaves into powder very fast.

Crafting and Using Bombs

Put five Amethyst Parts and one Aketine Powder into the Packaging Unit. It takes 10 seconds to make one Industrial Explosive. When it is done, take the bomb from the machine. Open your bag and select the bomb to throw it in Arknights: Endfield.

This clears the red rocks or hits the sensors that turn off lasers. Doing this can unlock things like Jump Pads so you can reach the Mountain Top.
