If you want to upgrade your Gear Bench to rank 3 in ARC Raiders, you’ll need to find 3 Industrial Battery and 6 Bastion Cell materials.
While the Industrial Battery is fairly simple, the Bastion Cell can be tough. To get, you’ll need to defeat Bastion ARCs, which are some of the toughest! Thankfully, there are some tricks you can use to farm them.
Read on, we’ll tell you how to easily get both of these material types!
Where to Find Industrial Battery & Bastion Cell | ARC Raiders
Industrial Battery

Let’s start with the easiest of the two items to get! For the Industrial Battery, you want to go to the Hydroponic Dome Complex on the northwestern part of the Dam Battlegrounds map.

You can find the Industrial Batteries on the steel shelves there, just waiting for someone to pick them up. It’s as easy as that!
Of course, this is a bit random, admittedly. Sometimes other items spawn and sometimes other Raiders grab them before you do. Nonetheless, this is the best and easiest spot to farm this item consistently.
Bastion Cell | Defeating a Bastion

Now, for the harder item… the Bastion Cell is an item that you can get as loot whenever you defeat a Bastion. As we covered in our guide on every ARC type, this is one of the toughest ARCs.
Before we go into how to defeat the Bastion, we recommend prepping up. Make sure to bring weapons with high ARC armor penetration, such as an upgraded Ferro or Anvil. Bring lots of ammo for them, as well.
Grenades can also be useful here, with the Wolfpacks being particularly potent. That said, whether or not you want to spend them on a Bastion is up to you to decide.

Once you’re ready, you want to go to the Plaza Rosa area in the southeastern part of the Buried City map.

As soon as you reach that area, you want to get up to the rooftops of the buildings there. Watch out for any patrolling drone ARCs in the area and take them out, as well.

When you’re finally in place, look down from the rooftop and try to find a Bastion. There is almost always one patrolling this area.

Once you spot the Bastion, it’s time to start unloading your arsenal on it! Try to aim for its joints and the fuel container on its back.
Managing to destroy the container on its back would be ideal, as it will instantly kill it!
When the Bastion looks at you and is about to fire, walk back a bit. You can easily break its line of sight here by using the slanted rooftops as your cover, which will block all of its shots.

After it finishes shooting, pop out of cover and fire at the Bastion again. Rinse and repeat until you eventually manage to defeat it, then go loot it to get your Bastion Cells!
So, there you have it, that’s how to find Industrial Battery and Bastion Cell materials in ARC Raiders. We hope this helped you deal with this tough ARC…
Now you know how to get these materials for your Gear Bench, but do you also want to unlock Gunsmithing III? Check out our guide on how to get the Sentinel Firing Core & Rusted Gear for that.
