Call of Duty WW2 Zombies - Undertaker Trophy / Achievement Guide - In The Final Reich, kill the Bomber with the shovel. [Bronze]

Before starting a zombies match on The Final Reich, you should pick the Medic Class with the Camouflage ability. This renders you invisible for a few seconds which is perfect to melee kill enemies without being attacked by them.
The best place to get the trophy is in the bunker. After turning on the power you can go through the middle door in the bunker. Behind that door are always 4 Bombers. Use the Camouflage ability before opening that door and then use melee attacks to kill one of them. The shovel is your default melee weapon, you always have it. They can take quite a few hits but in lower rounds it's easy enough.

Bombers also spawn in later rounds (starting at round 12+ or so). The bunker is just the first and easiest place to do it.
Keep in mind your Camouflage ability must first charge up. This happens automatically when you kill zombies. It will then show a red circle in the bottom right corner of the screen. Press L1+R1 (LB+RB) to activate the Camouflage once it's powered up.
