In Call of Duty: Black Ops 4’s third DLC Zombies experience “Alpha Omega”, the Ultimis and Primis crews arrive at a secret military compound within the Nevada desert. Call of Duty fans will know that Alpha Omega is an expanded version of the fan-favourite multiplayer and zombies map “Nuketown”, specifically the Black Ops 1 version.
Alpha Omega’s unique Wonder Weapons are the 4 elemental Raygun Mark II upgrades.
All 4 of them can be upgraded by 1 person in a single game and they can be stored and picked up by other players.
How To Unlock The Raygun Mark II Frames
One important thing to note before you start unlocking the Raygun upgrades is that you have to be playing in Online or Classic mode or else you’ll be locked out from obtaining the upgrade frames.
First, you must turn on the power and survive the lockdown in the Generator room. Then you have to interact with the 4 gas valves located at 4 of the 6 houses on the map as to stop the Nova 6 gas leak.
After completing this and successfully unlocking Pack-A-Punch you will be told by the AI “Rushmore” to interact with the computer in the Operations room. Next to Rushmore, there will be a Keypad with 4 digit slots, you need to put in the correct numbers as to unlock the frames.
You will need to interact with 4 monitors that have to be activated in a random order, and then fill them with Zombie Souls by killing zombies near them. You’ll know the monitor that is active because it will have a white screen instead of being off.
After filling each monitor, a number will be displayed on the screen, you need to remember the order of the monitors you completed. The locations for the 4 monitors are:
- APD Control – Bunker
- Diner – Bunker
- Yellow Backyard – Surface
- Site Entrance – Surface
After filling all 4 soul boxes, you need to input the numbers into the keypad next to Rushmore in the order you obtained them. This will trigger a short cutscene and the Raygun Mark II frames will be on the wall across from Rushmore, interact to pick one up.
How To Craft The Raygun Mark II Assembly Kit Buildable
Throughout the map, there will be 3 parts that need to be picked up to build the Assembly Kit. After picking up all the parts, it can be built on the buildable table directly above Rushmore in the Operations building.
The locations of the Raygun Mark II Assembly Kit are:
- Wire/Tubing – 2 Locations in Yellow House. On a table in the kitchen, 2nd floor on a shelf.
- Metal Canister – 2 Locations in Storage. On a barrel next to the door labelled “Exit”, on the corner of a shelf.
- Container of Element 115 – 1 Location in Solitary, 2 in APD Control. In Solitary, on the desk next to the female mannequin. In APD Control, next to the main computer controls or on the edge of the pyramid.
How To Upgrade The Raygun Mark II
All of the Mark II upgrades relate to one of the Pack-A-Punch ammo types. You can get one of the 4 alternate ammo types by putting a Pack-A-Punched gun back in the machine for 2500 points. The 4 ammo types are Kill-O-Watt, Cryofreeze, Brain Rot and Fire Bomb.
Raygun Mark II-V
This Raygun upgrade can be unlocked with the Pack-A-Punch ammo type Kill-O-Watt. In the Generator room there is a panel with yellow mist coming from it, shoot it with your Kill-O-Watt weapon and it will open, revealing the Yellow Canister, pick it up and head back to the surface.
There will be yellow sparks coming out from one of the electrical poles near the houses, shoot it with your Kill-O-Watt weapon and a yellow orb will appear on the pole. There will now be a new pole with yellow sparks, shoot it and repeat until all 5 poles are linked up to a generator just out the front of Yellow House.
Place the Yellow Canister inside the generator and a yellow circle will appear on the ground in front of it, you have to kill zombies whilst standing in it. You’ll know you’re done when you hear Rushmore say something and the circle disappears.
Take the Yellow Canister and a Raygun Mark II Frame to the Raygun Assembly Kit on the second floor of Operations.
The Raygun MK.II-V has unlimited ammo with a cooldown feature, ammo slowly regenerates over time for a total of 100. You can Pack-A-Punch it for extra damage as well as an extra 50 ammo capacity.
Raygun Mark II-X
This Raygun upgrade can be unlocked with the Pack-A-Punch ammo type Cryofreeze. On the surface, there will be a metal drawer with blue smoke coming out of it, shoot it with Cryofreeze ammo to open it and reveal the Blue Canister. The drawer can be in APD Interrogation, the garage of Operations or in Prisoner Holding.
During the next round, in the Bunker 3 zombies will spawn with the same blue smoke effect around them, shoot them once with Cryofreeze and they will be frozen solid, melee them and interact with the blue goo on the ground.
After this, place your canister in a broken container in the APD Control room, it is next to the telepad and has the same blue smoke effect. A blue circle will appear on the ground, you have to kill zombies whilst standing in it. When the circle disappears and Rushmore says a voice line, you can pick up the Blue Canister and take it to the Raygun Assembly Kit on the second floor of Operations with a Raygun Mark II Frame and craft the Raygun MK.II-X.
This Mark II fires in full auto and does pretty decent damage, but the real fun begins when you Pack-A-Punch it and you can now dual-wield them. They deal huge damage but chew through ammo really quickly, even with the Bandolier Bandit perk.
Raygun Mark II-Y
This Raygun upgrade can be unlocked with the Pack-A-Punch ammo type Brain Rot. The first thing you need to do is find a dirt mound with green smoke coming from it, there are 3 possible locations on the surface for it. There is one in the Green Backyard, the Yellow Backyard and a location in the Cul-de-Sac. You need to affect a zombie with Brain Rot and they will run to the mound and dig up the Orange Canister.
After this, on one of the Telepads there will be an orange orb, place a teleporter beneath it and shoot it. You need to repeat this once more, but after shooting the orb you take the teleporter. You’ll know you’ve done this correctly if you can see the orb in the teleporter animation.
The orb will now appear on some bags in Storage, you need to interact with it to put your canister down and an orange circle will appear on the floor, you need to kill zombies whilst standing in it. Once the circle is gone, you can pick up the Orange Canister and take it to the Raygun Assembly Kit above Rushmore in Operations and craft yourself the Raygun MK.II-Y.
This is easily the most powerful of the 4 Raygun upgrades, especially when Pack-A-Punched, this Raygun shoots out an explosive orb when uncharged, but when holding down the fire button it releases a charged attack that effectively destroys zombies up to around Round 70.
Raygun Mark II-Z
This Raygun upgrade can be unlocked with the Pack-A-Punch ammo type Fire Bomb. Around the map there will be a cabinet with red/orange smoke coming out of it, you need to shoot it with Fire Bomb ammo and it will open, revealing the Purple Canister. The 3 possible locations of the cabinet are in Green House Downstairs, Yellow House Downstairs or in the Lounge (Bunker).
After obtaining the canister, head to the Cul-de-Sac and look around at all of the houses’ chimneys. There will be one with purple smoke coming out of it, what you need to do is throw a Frag Grenade or Wraith Fire onto the chimney so the smoke disappears, then head to the fireplace of that building and place the Purple Canister.
This will make a purple circle appear on the floor, you need to kill zombies whilst standing in it. Once the circle vanishes, you’ll be able to pick up the charged canister and take it to the assembly above Rushmore in the Operations building and assemble the Raygun MK.II-Z.
This Mark II fires out multiple lasers like a shotgun, it hits really hard but has super low ammo capacity. When Pack-A-Punched, it gains damage, ammo capacity and the ability to be fired in full auto.
So that’s how you obtain all 4 upgraded Raygun Mark IIs in Alpha Omega. They aren’t necessary for the map’s Easter Egg storyline but they definitely are helpful during the boss fight and super fun to use.
