Overview
Easy way to kill the final boss on Über difficulty.
Phase 1
As Mesjaf said on Wolfenstein: The New Order 100% Achievement Guide：
Hide behind the glass shield and blast him with your laser gun untill he recharges. When he starts go for the gun and take down the zeppelins.
BTW everytime boss recharging u can only run half way to zeppline and you can recharge your laser gun on the corner.
Phase 2
That’s a trick .Jump down at the right side. Hide behind the Pipe and shoot the boss immediately .
Then the boss has a big chance of not moving.
But still boss can shoot u .
So shoot and hide from the left side of the pipe and you can kill him easily.
