This guide is for the blown away trophy on Gorod Krovi. You are required to kill a minimum of 10 zombies with one blast of the Dragon shield.
To obtain the shield you must collect the 3 pieces scattered around the map, just like in the previous 3 maps.
Head Piece- Infirmary building, middle floor on a shelf. Can be hard to see, just walk up against the shelf if you can't see it and you should be notified to hold
to pick it up.
- Infirmary building, on the top floor to the left of Stamin-Up. Can also be hard to see as it blends in with the debris behind it.
- Top of the stairs to the left between 2 boxes
Heart Piece- In Juggernog room on the chair
- On the side of a truck in the area between Juggernog room and Operations bunker
- On a shelf within the Operations bunker
Mouth Piece- Inside of the armoury next to the Wunderfizz
- Middle floor on a wooden wall next to door/hallway made from a subway car
- Inside the room next to the 500 point bridge
Once you have collected the 3 parts, take them to the buildable bench within the Operations Bunker and assemble the shield.
Now that you have the shield, simply run a train of zombies into a group of at least 10, (I recommend more than 10 for safe measure) then press
on the D-pad to pull up your shield. Spin around and press
to unleash a fireball from the shield which will decimate your train of zombies. After a few moments your trophy should pop.
