Dark Aether Rifts are end-game challenges in Modern Warfare Zombies (MWZ) unlocked by Sigils. You can temporarily enter the Dark Aether through the Act 4 mission called Bad Signal, but with Sigils, you can enter Dark Aether for a longer time by starting Dark Aether Rifts.

Where to find Sigils in Modern Warfare Zombies (MWZ)
The one thing we do know is that you need to complete the Act 4 Bad Signal mission to even begin the secret quest that unlocks Dark Aether Rifts. The best guess we have so far at unlocking Dark Aether Rifts is to use Locked Diaries and Sigils on the pedestals around the Dark Aether pedestal. However, our current knowledge about Locked Diaries and Sigils is limited.
We know that if you complete the Act 4 mission, you get the Icy Locked Diary in the Rift Reward. Even if repeated, you only get Icy Locked Diary, so we need to start there.
Currently, we don’t know how Sigils are unlocked, but we have a few ideas. The strongest idea is that Sigils are associated with Ammo Mods which would explain why each pedestal has an Ammo Mod on it. We think Sigils drop from Tier 3 Contract Rift Rewards; it seems like it comes down to RNG which wouldn’t be surprising.
Once you get a Sigil and a Locked Diary, you need to place them both on the correct pedestal and you should create a Dark Aether Rift. This is our best guess at how to unlock Dark Aether Rifts so far, but we’ll update this once the method has been fully figured out.
How to complete Dark Aether Rifts in Modern Warfare Zombies (MWZ)
According to Activision, Dark Aether Rifts are “otherworldly labyrinths” inside the Dark Aether where you need to complete increasingly difficult objectives to earn amazing rewards. I’m guessing that this is where we’ll find the new Schematics and new Wonder Weapon, or at least the RNG will be much better here if we are successful in beating the objectives.
