The Descent pack is available now for players of Call of Duty: Black Ops 3 on PlayStation 4 (and coming next month for Xbox One and PC players), and it's jam-packed with zombie-killing goodness in the new Gorod Krovi map, with enemies to take down and a whole slew of new weapons to unlock.

For this guide, we're going to discuss one of the best items you'll come across in the game – the Guard of Fafnir (aka the Dragon Shield). Once all the parts are tracked down and put together, this will be a totally badass item to have.

Turn on the Power in Gorod Krovi

You'll want to start by going to turn on the power. You'll find the switch located in the Dragon Control room. Flick it on and you'll see things light up, and can move on to the next step.

Find the Dragon Shield Heart in Gorod Kravi

From there, you'll need to track down parts of the Dragon Shield. You'll find the first portion of this Gorod Krovi weapon in the Department Store building near your spawn point, by going back to the department store building. Head up to the second floor and look on the right hand side. You'll see a Juggernog, along with a desk and a chair. The first piece should be right by the chair. If it's not there, go here next

After that, go back downstairs and look on the driver's side door of the nearby truck, where you'll find the second Gorod Krovi Dragon Shield part. Not there? Try this!

Go down to the Operations Bunker and hang a left, and you'll see a shelf. You'll see the Shield part there in if you haven't gotten it yet, and you can move on to the other part.

Find the Dragon Shield Head in Gorod Kravi

To find this part, head to the Operations Bunker and look for the back staircase, leading you inside the infirmary. You'll see the first spawn point at the very top, right between two wood boxes on the left hand side. If it's not there, go through the infirmary and look at the top of the hill, where you'll see some bunk beds. The Shield may be on the bottom bunk.

Finally, if it's not there, go back to the Infirmary and make your way to the top floor. You'll see a back wall, where the Dragon Shield piece should be if it wasn't in the two previous spots.

Find the Dragon Shield Mouth in Gorod Kravi

For the final piece, first look on the top floor of the infirmary and go over the bridge. You'll want to go left and look for a box covered in blood. That may be where this piece is.

If not, move on to the next location by going downstairs and moving straight ahead. You'll see a metal shelf, where the piece may be sitting right below some sand bags.

If that's not the case, it'll be in the third spot in Gorod Krovi, with arrows on the wall pointing the way from the second spawn point. Go hard right when you come to a fork, and look for a piece of wood at the bottom of the hill. This should be the final piece, and all that's left is to build.

Put the Dragon Shield Together in Gorod Kravi

Once all the parts are in play, find a workbench in the stage. There should be an option to put together the Guard of Fafnir at this point, and it won't take long to put together. Once that's done, you'll be able to use it to your heart's content, and lay waste to some enemies.

Good luck, and enjoy your new toy!
