Operation Poison Pill

Operation Poison Pill is a multi-step operation in Endgame and the key gate for accessing Glitch Fractures. Completing Step 10 of this operation is the primary prerequisite for entering Glitch Fractures. Like Operation Broken Mirror, progress persists across matches.

Tip

Glitch Fracture prerequisite: You must complete Step 10 of Operation Poison Pill before Glitch Fractures become accessible. This is the most commonly missed requirement. If a Glitch Fracture portal appears on your map but you cannot interact with it, check whether you have completed all 10 steps of this operation.

Overview

Operation Poison Pill involves neutralizing a Guild biological threat known as O.S.C.A.R. and injecting a virus into the Guild’s systems. The operation culminates in the Link Forger Glitch Fracture encounter and, upon Step 10 completion, permanently unlocks Glitch Fractures for that account.

With the release of Operation Poison Pill, the associated Nightmare Zone has a special mechanic: O.S.C.A.R. repeatedly respawns after each defeat, allowing multiple Exotic Fabricator uses within a single match.

Full walkthrough

1. Steps 1-7 - Specific step details are not yet documented. Community contributions welcome.

2. Step 8 - Defeat O.S.C.A.R. at the Winery Guild Strike as part of the operation chain. O.S.C.A.R. is located in Zone V (Nightmare Zone). Recommended Combat Rating for this step is CR 55+. See O.S.C.A.R. Boss Guide for full fight mechanics.

3. Step 9 - After defeating O.S.C.A.R., interact with the Exotic Fabricator and complete the post-boss objective. This step involves depositing the virus payload into the Guild system at the Winery location.

4. Virus Injection / Link Forger - The final step. Interact with the Glitch Fracture portal (Link Forger) that appears after the Guild Strike and complete the Glitch Fracture activity. Completing this step permanently unlocks Glitch Fractures for your account and grants the Nightmare Skill reward from the fracture.

   

Link Forger: the Glitch Fracture encounter

The Link Forger is the name for the Glitch Fracture instance tied to Operation Poison Pill. It is the first Glitch Fracture most players encounter. The encounter uses the Old Arsenal campaign space and involves six waves.

Wave structure

1. Wave 1 and 2 - Standard Fear and Guild soldier enemies. These waves serve as an introduction to the Glitch Fracture format.

2. Wave 3: Zone Capture - Players must hold a capture zone while enemies flood the area. Movement to the top of the tower removes exposure to Disciple-type enemies.

3. Wave 4: Disciple Mini-Boss - A Disciple (Specter) mini-boss wave. Standing on the broken wall inside the barn provides a line-of-sight advantage against the Disciple.

4. Wave 5: Shard Deposit - Players collect shards and deposit them at a marked location while defending against enemies. Coordination is important to deposit quickly.

Final boss: Skybreaker

After Wave 5, the Skybreaker boss appears. This is the culminating encounter of the Link Forger Glitch Fracture.

Dark Ops calling cards

Completing all three Dark Ops challenges tied to the Link Forger Glitch Fracture earns exclusive calling cards.
