Satellite Step
After collecting all three crystals, you need to make your way to each one of the Aether Reactors and insert the crystals into them. Make sure you insert in all three reactors.
Then make your way back to the OPC dome and enter the dome to start the next portal stabilization process.
The portal will once again close, and the system will shut down due to system overload.
After a dialogue between Weaver and Peck, Weaver will again talk to you and propose using the facility’s Satellite dish as a medium to power the OPC dome for the portal reopening.
For this step, head back to the Data Center and get another essence trap. It will help you out a lot and save you a ton of time when realigning the Satellite dish.
Before realigning the Satellite dish, leave one zombie at the end of the round and trap him using the essence trap so that he won’t be able to annoy you when realigning. The controls are a bit confusing when realigning, so it takes a minute to get used to the controls, especially on PC.
Head to the planning offices and interact with the computer by the door. The controls will be shown on screen, but where they move the dot won’t be indicated. You will have to figure it out on your own by pressing each key or button.
Move the small white dot to all the yellow orbs to find the correct alignment called the Requiem Disruptor Satellite. There will be yellow orbs with an American flag and even a Russian flag. You need to look for an orb with a “?” on it, instead of a country flag. You can see these flags appear at the bottom right corner of the screen when hovering the white dot on these orbs.
Once you’re on the correct orb, align the Satellite dish, and you will see the main Satellite dish at the Firebase rotate. After the alignment, Requiem will fire a laser beam at the dish that will allow you to open the portal.
At this point, you should have all your important perks and your RAI K-84 pack-a-punched at least twice. The most important perks you must have are Stamin-Up, Jugger-Nog, Speed Cola, and Quick Revive. Make sure to have a long-ranged weapon for the boss fight as you cannot attack the boss ‘Orda’ at close range. If you have the RAI K-84 wonder weapon double or triple pack-a-punched, you should be fine.
If you have enough salvage, it is highly recommended that you buy Monkey Bombs to distract the zombies while taking on the final boss. You are going to be swarmed by the zombies during the boss fight. One monkey bomb costs 1,000 uncommon salvage.
Also, make sure you switch your class to the one having Aether Shroud for sticky situations. Don’t forget you saved up a scorestreak during the assault round that can be used on the boss. You can also buy an artillery strike from the crafting table if you have enough high-grade salvage.
Wait for Weaver’s signal and run to the OPC dome where the portal is and interact with the control panel, which will initiate a cutscene that will show Samantha coming out of the portal.
Final Boss Fight
Once the cutscene ends, you will directly be put against the final boss called ‘Orda,’ also known as the “Elder God.” We first saw Orda during the high rounds of Die Maschine lurking outside the map in the woods. We also saw the hand of Orda when solving the Hand Easter Egg on Die Maschine.
Now, coming to the final boss fight, as soon as you jump into the fight, start spamming your RAI K-84 at Orda.
Quickly use your scorestreak, whether it’s an artillery strike or a napalm strike, use it on Orda, and you will see his health decline significantly.
Always aim for the head and mouth, especially when he opens his mouth for an attack. That’s when you can deal some serious critical damage.
Do not go near the Orda, or he will instant-down you with his big “hammer” hand.
Always loop around buildings and kill zombies if necessary. You will find that killing zombies is better than just avoiding them as it will give you some room and a chance to shoot at Orda. If you leave the zombies, more spawn, and they can easily overrun you in such a small spawn area.
Whenever you get hit by Orda’s fire attack, quickly take cover inside one of the buildings and try to keep as much distance as possible between you and the zombies. This fire attack is one of the reasons why you should have the Quick Revive perk for quick health recovery. Always be on the move and never stop.
After you’ve drained Orda’s health to zero, another cutscene will play that will show Orda dying and Samantha joining the Requiem to return to Weaver after bidding her farewell to Ravenov.
