How to complete Omega 86'd mission and defeat the Bio Armored Omega Thresher
Step-by-step guide to beating the mission:
Step 1: Reach the Fades District in Dominion
Progress through the main story until the Fades District opens in Dominion. Locate Beth in the Lakeside Properties on the platform to start the quest.
Step 2: Start "One Gassy Issue" quest
This second quest will lead you to the arena where the Bio Armored Omega Thresher spawns.
Step 3: Complete "One Slimy Issue" side quest
Follow the objectives given by Beth to complete this side quest, which prepares you for the final encounter.
Step 4: Prepare your loadout with effective weapons
Bring Cryo, Corrosive, and Fire elemental weapons. The Omega Thresher has a layered armor system: first armor, then flesh. Using the right damage types helps break shields and health faster.
Step 5: Enter the arena and engage the boss
Navigate inside the arena in the Fades District. Expect to face a highly armored Thresher that requires careful aiming and elemental damage to defeat.
Step 6: Use tactics and teamwork as needed
Focus on weakening the armored shell first with Cryo or Corrosive weapons. Then switch to Fire-based weapons to finish off the exposed flesh. Maintain mobility and use cover to survive the attack patterns.
Step 7: Defeat the Bio Armored Omega Thresher
Once defeated, the mission completes, granting progress towards unlocking UVH rank 2 and the associated Wildcard missions.
Why completing Omega 86'd matters for UVH progression
The Omega 86'd mission is one of the four key challenges for unlocking UVH 2. Alongside other challenges (such as killing bulkheads and other bosses), this mission increases the difficulty and rewards of the game by raising enemy stats and loot quality. Upon completion, you can take on new Wildcard missions offered by Lilith, which lead to further UVH ranks and endgame content.
Expected drops from Bio Thresher Omega
| Weapon | Type | Manufacturer | Drop source / Where it can drop | Region / Location | Requirements / Notes |

| Truck | Sniper Rifle (Legendary) | Jakobs | Can drop from the Bio-Thresher Omega boss fight | Fades District, Dominion | Must complete side quests One Gassy Issue and One Slimy Issue first. |
