Like past Zombies maps, Call of Duty: Black Ops 4 has a special Wonder Weapon that players can collect by solving puzzles. The Ancient Rome-themed Zombies map IX features a Wonder Weapon called the Death of Orion, which is necessary to complete the easter egg as well as unlock some other achievements in the game.

Here is a step-by-step guide on how to get the Death of Orion Wonder Weapon on IX. We recommend Call of Duty: Black Ops 4 players make an effort to familiarize themselves with the map and its various locations before attempting to do this, however.

1. Pack-A-Punch

The first step to getting the Death of Orion Wonder Weapon on IX is activating the Pack-A-Punch. As we detailed in our Pack-A-Punch guide, doing this is a matter of visiting the Altar Room in each of the four towers, hitting the gong there, and then killing the champion that spawns. Each champion will drop a head that players can collect and take to the underground Temple, where they can be put on spikes. This in turn activates the obelisk, which serves as the Pack-A-Punch on IX.

2. Build the Acid Trap

The next step is to build the Acid Trap, which is fairly simple to do because the parts don't seem to change spots. Two of them can be found in the lower floor of the temple in opposite corners - the metal chains and the gear. Once these have been collected, players will need to head to the Arena and start completing the challenges if they haven't done so already.

Once three challenges have been completed, a small pot will spawn on the center podium. This is the last part needed to build the Acid Trap, but there's something else players need to do before they actually use it.

3. Scorpion Key

Before players need to use the Acid Trap, they need to get a special statue head to melt down with the acid. To get this statue head, players need to head to the underground area again, and go to the Danu-Ra Temple Entrance. There is a small metal grate here that is blocking a long hallway. There is a flaming pot at the end of the hallway, so shoot it. Then go up to the bridge that connects the Danu and Ra Towers and look at the ground between it and the arena. There should be a flaming arrow here pointing to one of the four towers. Follow the arrow to whatever tower it's pointing at to start looking for the statue head.

The statue head has four different spawn locations, all depending on which tower it spawned in.

• Danu Tower - In the water in the Arboretum.
• Odin Tower - On the grate in the floor in the Cauldron room.
• Ra Tower - Check the corners in the Burial Chamber, near flaming pots.
• Zeus Tower - In the Bath House underneath the curtains.

Hold in the interact button to pick up the statue head (there will not be a prompt) and then head to one of the Acid Trap build locations. These look like traps on the wall, and can always be found on the stairs leading from the Altar Room in each tower to the room below. Build the trap, then place the statue head on the grate and activate the trap.

Kill zombies and wait for the acid trap to do its thing. Once the trap is done, the Scorpion Key will be where the statue head was. Pick it up and move on to the next step.

4. Gold Vase

Now players need to get the Gold Vase, which can be a little tricky. Basically, they have to get max Crowd Affinity twice in a row. Crowd Affinity is represented by the skeleton hand in the bottom left-hand corner of the screen. When that hand is giving a thumbs up, is green, and on fire, that means Crowd Affinity is at max.

Usually the crowd will reward the player with something in the Arena, like max ammo or another power-up. Swipe at the reward with a melee strike to reject it, which is helpful for keeping Crowd Affinity high. The same goes for the rewards that are given when completing the nine Arena challenges; reject them to keep Crowd Affinity as high as possible. It also helps to avoid taking damage, shooting instead of throwing grenades, and killing champions.

Eventually, the Gold Vase will spawn at a random location in the Arena. Just move around the circle and check the ground to find it. After grabbing the Gold Vase (like the Scorpion Key, there will be no prompt), head to the Arboretum in the Danu Tower and check the tree closest to the stairs. There is a hole on the side that can be hit with a melee attack. Do so, then place the vase underneath the poison that starts spilling out. Complete a whole round and return to the vase to find it full.

5. Mystery Box - Death of Orion and Serket's Kiss

Collect the full vase and then find the mystery box. The mystery box will always spawn in the Fallen Hero room in the underground area first before eventually moving to other places on the map, but upon locating it, approach it from the side. There should be a prompt to dump the poison on the box, but this may take a few minutes to appear. At any rate, put the poison on the mystery box when allowed to do so, and then make a purchase from the box for the usual 950 points.

The weapon that spawns from the box will always be the Death of Orion after putting the poison on it. This Wonder Weapon is basically a scorpion that is especially powerful when using the charge attack. It's tied to a couple of different achievements on IX, like killing nine zombies with a single shot of a non-charged attack, as well as using the Pack-A-Punch to transform it into Serket's Kiss.

In the meantime, it's worth noting that other players that want to collect Death of Orion will be able to do so if they keep hitting the box. Building it the first time adds it to the roster of possible weapons that can spawn in the box, and it's definitely worth it for everyone to get their hands on the weapon.
