Call of Duty: Black Ops 4 features three main Zombies experiences, and this one focuses on IX. In this short guide, we’ll tell you where to find all the pieces of the Brazen Bull to get this awesome shield. Before starting, you should know that the parts may take a minute to spawn in each location. If this first piece isn’t where you expect it to be when you look, it may pop in later.

The first piece is located close to the spawn area. When you spawn, go right and you’ll come to the temple of Ra. Go up the small staircase, which it opens up to a main room with statue and some sarcophaguses. The first piece spawns in one of a few places.
