Easter Egg Guide: -- Part 1 -- Part 2 -- Part 3 --

Hi guys,

let's cut through the fluff. If you're reading this, you're either a Black Ops Zombies veteran looking for another challenge or someone who genuinely believes there's an inferno demon that needs taming. 

Either way, welcome to the chaos of Rex Infernus and its Easter egg!

This guide will get you through the entire Easter egg, start to finish, giving as many top tips as you can shake a pointy stick at.

Setup to win, not setting up, is preparing to fail!

Don't show up with pistols, seriously, they're useless. The right weapons can make or break your attempt at defeating the zombies hordes and the Rex Infernus boss:

• Assault Rifle (Long-range build) – Good all-around damage
• LMG Build – Specifically the Mammoth LMG 
• Marksman Rifle – The Nova Line build works great here 
• Primary Weapon – Triple Pack-A-Punch weapons with legendary rarity
• The New Wonder Weapon – Should be included in your loadout 

Field Upgrades, Make Sure to Choose Wisely

Consider these options for this map:

• Aether Shroud – Provides defensive utility 
• Frenzied Guard – Helps manage aggression levels and keeps zombies from swarming too close 
• Kazimir Grenades – Essential for blocking zombie attacks during boss phases 

Step 1 - Pack-A-Punch Activation

Once you jump into the map, your first objective is straightforward but important and here is a very quick overview of how to activate the Pack A Punch Machine in Rex Infernus:

1. Activate Pack-A-Punch – The game will prompt you on how to do this, however I have created a step by step guide on Activating Pack A Punch for you if you need help.

2. Navigate Through the House – You'll journey through the house answering a strange phone call

3. Reach the Main Map – Make your way back to the main area after completing the sequence 

4. Place World Seed – Follow the instructions to place this critical item 

Then follow the ritual steps:

- Follow the TWO DREADED SKULLS that will guide you, shooting them as they make their way to two main chambers before exploding into flames. Each skull will drop a flaming BRAZIER which you can pick up the UNSURPED FLAME, then take it to the Pack A Punch Machine

- You will use the UNSURPED FLAMES from each dreaded skull to light both braziers on either side of the Pack A Punch Machine, doing this twice, then rotate both crank wheels to unlock Pack-A-Punch 

- Void pedestals will spawn with a grapple hook lasting 30 seconds, then grapple orbs and pull them to Pack-A-Punch to get purple flames, this is actually part of the temple puzzle and 4 trials. Mainly related to the Nyxara puzzle.

Temple Puzzles - The Four Trials

Once the braziers are lit, you'll have multiple easter egg steps to complete in any order through each of the main Shadowsmith temples, scattered around the map in various locations.

Nyxara Temple - Purple Flames and the Crystal Beam Puzzle

Before tackling Nyxara, head to the DRAVAKAR TEMPLE first:

- Jump up on the entrance wall, wall bounce, and break it with an explosive or PhD Flopper to get the "FRACTURE OF NIXARA".

- Grapple into the main chamber and place a crystal on the wall

- Throw the PURPLE ASTRAL FLAMES at the large eye on the wall to activate it and shoot crystals until beams bounce off them, eventually bouncing off other and ending up the energy pulses hit a closed doorway and dissolve it

- Keep shooting crystals with your grappling hook until they melt the door, revealing Nyxara's Inner Sanctum

When Inside Nixara's Inner Sanctum:

- Walk towards the large vines and let them drain your health while taking out zombies 

- Survive until the vine life bar fills up to unlock a new secret area accessible from round eight onwards, that is a FOREST AREA and is part of the TWINS AMMO MOD MASK.

This section has actually been covered in my guide for the TWINS AMMO MOD MASK GUIDE. Click to read and it will open in a new window, then when you get to the part where you have charged up the VINES of the tree, come back to here.

Veytharion Temple - Water Puzzle

Inside Veytharion , you'll find four stone blocks outlined when you are using Death Perception:

• Water block, found under the green lantern in VEYTHARION SANCTUARY

• Fire block, found in the VEYTHARION MAIN CHAMBER next to Gobblegum machine

• Plant/Leaf block, found on top of the ZOMBIE SPAWN WINDOW beside the MULE KICK PERK MACHINE in VEYTHARION SANCTUARY

• Air/Hand block, found on the bottom floor by zombie spawn window, in the same room as MULE KICK PERK MACHINE in VEYTHARION SANCTUARY

Pick up all of these BLOCKS and move them into the room in the VEYTHARION SANCTUARY beside where you originally picked up the WATER BLOCK, for easy access to them, as we will be using them in a puzzle next that needs solved.

The Elemental Puzzle, The Eternal Battle of Fire vs Water Continues

If we head back to where we picked up the WATER BLOCK, on the wall you will notice that there is grooves in the wall where there is room to place these blocks onto the wall.

They will need placed onto the wall in a very specific order, so that we can solve this ancient puzzle.

For each of the blocks, pick them up in the following order and place them into the slot in the wall, one on top of another.

The pick up order is: Water → Plant → Hand → Fire

When all blocks are inserted correctly, the outline of them will GLOW YELLOW, letting you know it is the correct order.

We now have a puzzle on our hands, where all the blocks in the small tower we have created, needs to be moved to the far side of wall, left to right.

We need to take the FIRE BRICK from the stack and place it on the right hand side groove in the wall to the right of the tower, of where there are 2 place holders.

We then need to place the HAND BRICK, in the left of the placeholder.

We then need to move these bricks using the LARGE WHEEL in the middle of this wall. To activate the wheel and the moving process, run up to the WHEEL and melee it. 

This will activate an ORANGE ENERGY that slides the bricks along to the far side. This now means that FIRE and the HAND bricks are on the right hand side.

Certain BRICKS do not mix with each other, for example, FIRE does not MIX with water....common sense.....nor does FIRE mix with the PLANT BLOCK.

Now the bricks are on the far right hand side, take the FIRE BRICK out of the 2 placeholders and place it in the TOWER style slot on the right hand side, leaving the HAND BRICK in the transporter.

Then melee the WHEEL again in the middle to send it back across to the left hand side with the HAND BRICK in tow.

When it gets there, pick up the WATER BLOCK and put it on the right hand side of the transporter placeholder and melee the WHEEL to send it across.

Now as we keep saying, FIRE AND WATER DO NOT MIX! Sorry for shouting, so that means we will have to take the HAND BRICK this time off and drop it into the slot on the right, on top of the FIRE BRICK, keeping it separate from the WATER BRICK.

Then select the BOTTOM FIRE BRICK and put it back into the transporter onto the right hand placeholder. Then also take the HAND BRICK and place it on the LEFT HAND PLACEHOLDER. 

Now the WATER BRICK is the only one on the right hand side on its own.

Then....you guessed it, melee the wheel in the middle to send them across again.

When it gets there, pick up the HAND BRICK and place it on top of the PLANT BRICK. Then pick up the FIRE BRICK and place it on top of the HAND BRICK.....you still with me?

Now pickup the PLANT BRICK and place it in the right hand placeholder of the transporter, then pick up the HAND BRICK and put it on the left hand side placeholder and melee the wheel once more to move it to the other side.

Once it gets there, put the HAND above the WATER BRICK, then place the PLANT BRICK on top of the HAND BRICK.

Then take the WATER BRICK and place it on the right hand transporter placeholder, then take the HAND BRICK and place it on the left hand again.

Then take the WATER BRICK and place it on top of the PLANT BRICK, then melee the wheel to send the HAND BRICK on it was back over on its own again.

When it gets over to the left hand side again, place the FIRE BRICK on the right hand side placeholder of the transporter....then melee the wheel in the centre again one more time.

When on the right hand side, take the HAND BRICK and place it on top of the WATER BRICK, then place the FIRE BRICK on top of the HAND BRICK and that should complete the puzzle!

That went on for a long time so I think you for sticking with it and hope you paused and had a cup of tea or coffee to recharge the brain cells after that one.

When all of them are in the correct order, they will GLOW YELLOW together, their outlines, letting us know we are successful and geniuses when it comes to ancient puzzles.

The wall where the wheel was located will open up and it will reveal a FREE RANDOM PERK and a POOL OF WATER that will be used later in the Easter egg.

Dravakar Temple - Riddle me this, riddle me that puzzle

The next puzzle we will take on is locate din the DRAVAKAR TEMPLE area of the map and I would recommend turning on the subtitles when attempting this. 

If you head into the DRAVAKAR SANCTUARY area, you will notice on the wall there is a BLUE WALL QUOTE that Dravakar will read to you, which you will need to note down exactly what he says.

Four different riddle combinations exist, each with three switches (left, bottom, right), here are the 4 possible quotes:

• "Runner travels to stars while moons and galaxies stay true"
• "Drift to runner that travels moons who borrow from galaxies when stars stay true" 
• "Drift to stars that remember moons, who borrow the runner that travels the galaxy" 
• "Remember galaxies that drift to moons, who borrow the runner that travels the stars"

Depending on which riddle you get, there will be 3 switches located in this area, which you are going to need to hit a certain number of times to activate the central pillar in this area to dropdown from the ceiling, revealing a secret room above which you can grapple up to:

The 3 Switch locations

The switches are all located in the DRAVAKAR SANCTUARY area, and they are found:

• To the right hand side of the ZOMBIE SPAWN WINDOW, to the right of the ARMOR WALL BUY in this area

• Another switch is facing the riddle text on the wall you had read out to you. If staring at the wall of text, it is to the bottom left of where you are, in the wall in the corner of the same room you are in

• The last switch is in the corner beside a ZOMBIE SPAWN WINDOW, to the very far left of where the GOBBLEGUM MACHINE is located

Don't worry if you mess this up, if the pillar does not come down after hitting the 3 SWITCHES, then activating the CENTRAL SWITCH in the pillar in the centre of the DRAVAKAR SANCTUARY. 

All you have to do is simply go to the next round and retry it again to restart the sequence.

Once correct, the middle pillar lowers, revealing a secret passage to DRAVAKAR'S INNER SANCTUM in the ceiling, along with an anvil for crafting the levels wonder weapon later on.

To get up here, simply grab the grapple gun and grapple your way up to the top of this room and there the ANVIL will be sitting with a GLOWING BLUE FLAME.

Now we can move onto the 4th and final temple.

Caltheris Temple, starting to feel the pressure!

When you head into this temple, and go down the steps, make a left and head to the left hand side of the downstairs, CALTHERIS MAIN CHAMBER area. 

You will notice in this area there is 4 PRESSURE PLATES sitting on the ground.

These four pressure plates activate timed sequences, where you need to shoot the GLOWING ORANGE BOXES on the walls, ceilings etc., before the pressure plate sinks down into the ground:

• First plate (starting from far left) → 4 boxes on wall

• Second plate → Another 4 boxes in new locations on left and right hand sides of the area

• Third plate → Some behind you, including ceiling and left/right

•  Final plate → 4 squares on right hand side wall

Once successful, wall crumbles revealing lanterns and purple orbs that travel to NEXUS FORGE area of the map. Interact with the LANTERN and it will throw the PURPLE ORBS out towards the NEXUS FORGE section of the map, where the PACK A PUNCH MACHINE is located, as well we some sections between the temples themselves.

If you fail any of the pressure plate steps on any 4 of them, don't worry, you can come back to the same pressure plate you failed on in the next round and resume trying to complete it again from that point on.

Now we can move onto the next part were we will be doing 2 Easter egg steps at the same time, why you might ask?, because we like to be efficient.

I am wondering what the wonder weapon....wonders?

If we have activated all four temples before round eight when we get to this point, we are in a very good position as far as the Easter egg goes, as well as a few steps ahead of ourselves...which is nice.

If you head to the NEXUS FORGE area of the map and looks towards HER HOUSE area, there is a BASKETBALL sitting just in the BROKEN PART OF THE ROOF. 

This basketball is a slight dark orange or brown colour, which makes it hard to see without a sniper scope, however if you shoot where you can see in the images below, it will cause the BASKETBALL to fall off the roof.

It will eventually bounce down onto the ground and fall of the cliff the house is on, over to the left hand side of the door.

Once it falls off, simply progress onto the next round, then return back to this exact location for the next step.

When you return on the next round, you will notice that there is a BLUE SYMBOL at a specific WINDOW on the front of the house. You will need to take note of what this simple is and which order it appears on the front of the house / window location.

Take a screen shot on your phone or on Xbox / Playstation so we can refer back to each BLUE NOTES location.

Now we can head over to the NYXARA INNER SANCTUM where the VINES are located and we can consume the SEED that is tangled in its roots.

This will then teleport us to a secret FOREST area. This area is where you play the 3 mini games with the twins in order to obtain the TWINS AMMO MOD MASK.

When we spawn into the secret forest, we will need to find 3 DEAD BODIES in the forest, in order to allow us to build the WONDER WEAPON on this map.

Unfortunately there is no mini map in this area, so hopefully you can find them via the images shown below:

Once you interact with each body, there is a small cut scene from the WARDEN and when it finishes, you will be able to pick up a PART for the wonder weapon from each body, that is highlighted in YELLOW.

Location 1 for the body

There is one close to the centre of the map, propped up against a LARGE ROCK. 

Location 2 for the body

There is a partially destroyed CABIN near the back of one area of this forest, where there is also a small stove. There is a body laying on the wooden floorboards of this cabin.

If you look to the left of the body, you will notice some BLACK VAPOUR coming from the floor. Melee this BLACK VAPOUR and it will destroy the floorboards.

Then interact with it and after a short cut scene again, you will then be able to pick up the item.

Location 3 for the body

This is found in a corner of the forest where the rocks at the sides, form a small CAVE. If you go into this cave, there will be a body laying on the ground in plain sight.

Again, simply interact with this body and it will play the cut scene, then you can pick up the item laying on the floor beside it.

If you are quick enough in the forest, you can get all 3 of these parts in one go.

If you don't, manage to get them in one go, don't worry, you can simply progress onto the next round and then return in the same way to get the parts you had missed.

Now we have the 3 parts, this means we have all 3 parts of the WARDEN'S BLIGHT in your inventory and can craft the wonder weapon.

To do this simply head back over to the DRAVAKAR SANCTUARY and grab a grapple hook then head over to the DRAVAKAR INNER SANCTUM, which is accessible through the roof of where the switch was located in the centre of this room to solve the WALL RIDDLE PUZZLE.

Once you get up there, you will find DRAVAKAR'S ANVIL which will allow you to form the WARDEN'S BLIGHT WONDER WEAPON.

When it is crafted, pick it up and try to get it PACK A PUNCHED as soon as possible. This is because when it is Pack A Punched, it will give you an additional ability that will be needed later on in this Easter egg.
