Call of Duty: WWII

This trophy is for obtaining the Shield weapon and upgrading it. Note that only the person that completes the trial will earn the trophy.

Here are the steps to this trophy:

Step 1: Fill up the 3 Blood Pools.

There are 3 Blood Pools around the map, and you just need to kill 5 zombies while they are in close proximity to them. These can be done in any order.

The first Blood Pool is located in the Ice Caves, on the left side. It’s right before the Archives entrance.
The second one is located in the Morgue, directly next to the entrance from the Ice Caves.
The final one is located at the Overlook, next to the entrance to the Archives. However, this one is missing its stone plate. The plate is located in the Morgue, it’s at the bottom of the area on a pile of bones. Make sure you place it in the Pool before getting the kills.

Step 2: Grab the Shield.

Head to the Blood Altar, a Wustling will spawn from the huge pool and it will have the shield on its back. Simply kill it and grab the shield. Note that even though the shield is on its back, you can still shoot through it to hit the weakpoint.

Step 3: Power up the Blood Pools.

This step is really annoying. What you need to do is go to each of the Blood Pools with the Shield equipped and look for one that has red mist coming out of it. You need to bring a fully charged Corpse Eater to it and kill it while it’s standing in the pool. Make sure you move away from the explosion it makes though! If done correctly, you will see a pattern forming on the blood pool.
Once you have done this at all 3 pools you’re done, but make sure to remember the order you did them and what patterns are on them! That’s very important for Step 5!
(You can spawn Corpse Eaters either by taking a teleporter to PaP, or by shooting hidden ravens around the map)

Step 4: Obtain the speaker and radio.

Easy step, but cannot be done until at least round 8, as you will need a Bomber zombie for this.

Once you have a Bomber zombie, take it with you to spawn.
Near the Luftwaffe wallbuy, you may notice a pillar with a large metal sheet on the ground in front of it (to the right if facing the Caves). Look underneath it and you should see a radio and a white speaker. You need to stand as close to it as possible and have a bomber zombie blow up on it. Pick both items up to complete this step.

Step 5: Solve the pattern puzzle in the Blood Altar.

Head to the Blood Altar, and you’ll notice 2 small pillars next to the Blood Pool, you need to place the radio and speaker on these 2 pillars (You might need to crouch to place the speaker).

If done correctly, the pool will start boiling and patterns will appear. You can change the pattern by holding on the radio.

What you need to do is use the patterns from the blood pools in Step 3, and get exactly 1 zombie kill on each pattern. If done correctly, the patterns will alternate really fast. If you make a mistake, kill a few zombies on the pool until you see the pattern change, this signifies a fresh start again.

Step 6: Complete the Trial!

You need to stand on the blood pool in the Blood Altar and let yourself be killed. You’ll teleport to the trial arena, so pick up the Shield to start it.

This trial is incredibly easy. You will kill zombies like normal, then a light will shine from the distance that slowly damages you. Just face towards it and hold to block with the shield. Repeat once more and the trial is complete and the trophy is yours!
