In Star Wars Battlefront, bringing down an AT-AT Walker seems to be difficult for players. If you pick up a vehicle power-up while playing on the Rebel side in the Walker Assault multiplayer mode, you can bring down an AT-AT to score big for your team. You can also practice in one of the solo Training Missions in Star Wars Battlefront to bring down an AT-AT Walker.
To bring down an AT-AT, simply fly your plane and target it near the legs of the Walker. There should be a button prompt that pops up, and allows you to release the cable to start towing it. After pressing the button, a black bar will pop up in the middle of your screen, and you will see a small plane icon in the middle of it. Your approach here should be to keep the icon within the boundaries of the black bar. Simply use the right stick to move up and down to keep the icon within the boundaries of the black bar.
You’ll also see four blue icons on the left of the bar. You’ll successfully bring down the AT-AT walker if all four buttons lit up. If you do it with accuracy, the AT-AT Walker should tow instantly in Star Wars Battlefront.
