MW3 Zombies: How to complete Union mission

Here’s a step-by-step guide on how you to complete the Union Story mission in MW3 Zombies.

Once you enter the Rift located in Urzikstan’s E4 map location in MW3 Zombies, marked with the Union waypoint, you’ll need to enter the Dark Aether and begin the story mission objectives.

  • Once the Orbs are taken down they will transform into Crystals, inspect them by pressing the interact button when in front of them. After this, a sequence will appear in the Crystals, to weaken them you’ll need to find the symbols located in the buildings nearby. Be sure to shoot them in the same order they appear in the Crystal sequence.
  • If done correctly, each Crystal will turn red enabling you to shatter it by shooting it with your gun.
