Attuned Assault Cannon

All Blaster Cannons with the Bunker sound type have the same sound, including the Attuned Assault Cannon. This isn't the official name, and this Blaster Cannon sound type may be labelled something like weaponrangedcannonnormal01 in the background of the game.

I do not have a video of the Attuned Assault Cannon, but you can watch a video of the GT-13 ST Assault Cannon weapon to hear the Bunker sound type, which is the same as the Attuned Assault Cannon.

Eternal Chapter weapons can be earned through the Knights of the Fallen Empire and Knights of the Eternal Throne expansion chapters. Each weapons piece comes from a specific chapter, and which specific look you get depends on your current Combat Style. You can earn these in the easiest version of the Chapters, you do not need to play Veteran or Master Mode. There are versions of this weapons with the same name but different looks from MK-1 to MK-8 - but only the MK-5 and MK-6 versions look like this from the Chapters. The Chapters just offer different-colored borders (green, blue, purple) depending on the difficulty, but three qualities have the same look.
