In Arc Raiders, the Bastion is one of the tougher enemy types, found on all four maps. It's a slow moving, heavy plated, grey-black, crab-like Arc that'll shoot at you and is hard to defeat without cover. But it also holds valuable loot.
If you're not sure if it's a Bastion you're up against, simply ping it, and the character will say what it is.

Here's where you can find Bastion on the four maps in Arc Raiders.
Bastion Locations
You can find Bastions wandering around the maps. But there are some maps where they're more easily spotted than others.
Spaceport
You'll generally spot Bastions near the Container Yard area on the Spaceport map. We found it lumbering about near the West Container Yard.

Buried City
On Buried City, Bastions can be found in the New District area, or to the right of Old Town.

They also tend to roam around Plaza Rosa near a tall church-looking tower.

Blue Gate
On Blue Gate, you can find Bastions in the Headhouse region (right of Reinforced Reception) as well as the Checkpoint region. They're also known to spawn near the Warehouse Complex so do check that general vicinity too.

Dam Battlegrounds
On Dam Battlegrounds, you can find the Bastions roaming about in the swamps (next to the dome complex) and south of the North Complex, past the bridges.

Once you've found the Bastion, make sure you have a good vantage point, or good cover when you taken it on.

Once you defeat it, make sure to loot it. You're bound to find the Bastion Cell as well.

Finding and defeating Bastions in Arc Raiders can be a little tough, but the endeavor pays off with high-value Bastion cells.
