Kill Zombies Inside the Circle Using the Correct Ammo Mod

Once the obelisk's seal has been activated, you can start killing zombies inside the circle using the required Ammo Mod to power it up. If you kill a zombie with the incorrect Ammo Mod, the whole process will fail and you will have to do it all over again.

Enter the Unstable Rift Portal

After successfully activating 3 Obelisks, the location of the Unstable Rift portal will pop up on your map; marked by a red circle icon. Head over there and interact with the portal to initiate a vote. Once you or all your squadmates have voted Yes, you will immediately be transported to the Unstable Rift.

Survive 5 Waves of Endless Zombies

Inside the Unstable Rift, you will have to defend yourself against 5 waves of endless hordes of zombies. Each wave has a Special Zombie boss that you will have to defeat before you can advance to the next round. Upon killing the final boss in the fifth wave, the exfil portal will appear which you can use to safely exit the Unstable Rift.

In addition, you will also start out with all perks equipped, a free weapon upgrade to Pack-a-Punch Level 3, a Golden Armor Plate, and a Self-Revive Kit.
