Command Killer Glitch Fracture Guide

Operation Wall Breaker is Act III of BO7 Endgame, live with Season 4. Nine steps, all linear, all mandatory. You do not get to skip to the fun part. Progress through each step in Hightown until you reach Step 10: defeat the possessed convoy in Avalon: and the Command Killer Glitch Fracture location is revealed on your map. Congratulations, the game has now decided you are ready.

Unlike the previous operation (Broken Mirror), Wall Breaker starts at Zone I, meaning you don't need a maxed-out operator just to read the opening cutscene. The difficulty scales: Zone I through Zone IV, then Nightmare for the Glitch itself. Do not walk in unprepared. The Nightmare Zone difficulty is not rhetorical.

Pre-requisite: If the Guild Strike Boss has already been defeated in a previous session, the Glitch Fracture spawns on the map immediately. You don't re-do step one.

Before entering, use the Exotic Fabricator: unlocked by defeating the Strike Boss in Nightmare Zone. It upgrades your weapon to Exotic rarity. If your weapon is already Exotic, it applies a second upgrade effect. Skipping this is a personal choice, in the same way skipping a seatbelt is a personal choice.

All 6 Waves: What Happens

Six waves, two objective sets per area. The timer exists. It never felt punishing in testing, but it's there, watching you fail slowly.

Wave	Type	What You're Actually Doing	Kill Them With
1	Elimination	Tight corridor. Lower-tier enemies flood in. Reach the kill threshold twice.	AoE weapon. Reboot with grenade rounds destroys this wave.
2	Elite: Amalgam	Cafeteria. Tables everywhere. Amalgam Elite with a harpoon hook that heals it when it pulls you in.	Aim the crit spot. Don't get harpooned.
3	Defend	Two tubes eject from the ground. Defend both against multiple small waves. Manglers spawn but target you, not the tubes. Fears target the tubes.	Prioritize Fears over Manglers. Check both tubes constantly.
4	Boss: Oscar	Oscar variant with extra HP. No shield skill. No special abilities. He is just annoying and durable.	Keep moving. Dump damage. He dies eventually.
5	Capture	Three capture flags. Glowing yellow zones. You pick the order. Stand in circle, survive enemies, repeat.	Clear enemies before capping. Don't try to multitask.
6	Final Boss: Cursa Bear	Fast, aggressive boss from the possessed convoy. Heals via beehives. Destroy beehives the moment they appear or watch him undo your progress.	Constant movement. Immediate beehive destruction. Burst damage windows.

Wave 3: Tube Defense Notes

This wave runs the longest. A filled defense meter at 100% with both tubes intact advances you. Lose a tube and you're in trouble. The Mangler ignores the tubes: it wants you. Fears are the actual threat to the objectives. Handle them first, let the Mangler chase you while you clean up.

Wave 6: Cursa Bear Boss

The Cursa Bear boss fight is the same enemy from the possessed convoy activity in Avalon. Fast movement, constantly repositioning, puts you permanently on the back foot. His one dangerous trick: reaching a damage threshold causes him to deploy beehives. Those beehives heal him. Destroy them immediately or watch your damage output become irrelevant. Once enough damage lands, he's done.

Do not ignore beehives. Every second they survive is HP returned to the bear. Burst them the instant they appear.

Loadout

Go in with your best weapons for Endgame Nightmare. This is not negotiable. The Reboot with grenade bullets handles Wave 1's crowd problem cleanly. Exotic-tier weapons are the floor, not the ceiling. Skills and abilities that manage crowds outperform single-target precision across most waves here: the single-target moments (Oscar, Cursa Bear) don't require specialist loadouts, just sustained damage output.

Command Killer Glitch Fracture Guide FAQ

Do I need to complete all of Operation Wall Breaker to access the Command Killer Glitch Fracture?

Yes. All 9 steps in order, then defeat the possessed convoy in Step 10. Then it unlocks.

What happens if I fail to destroy the Cursa Bear's beehives in time?

He heals. Your damage output becomes a donation. Destroy beehives the moment they spawn, no exceptions.

Can I replay the Command Killer Glitch Fracture after completing it?

Yes. It stays on the map permanently. Replay it with each of the three required operators for skins.

Is the Visitor's animated camo worth three full runs?

That depends entirely on how much you like looking at a weapon camo. The fracture isn't long.

Does Oscar in Wave 4 have his nightmare zone shield skill?

No. He has extra HP and no shield. He's slower than usual. Sustained damage ends it.
