The final mission in Act 3 is quite tough, but it’s arguably easier thanthe Shepherd mission in Act 2.Defeat Zakhaev features a boss fight and many mercenaries, so be sure your character is fully geared before starting this mission. You’ll want a three-plate vest, at least one Self-Revive Kit (more if you’re solo), and as many perks as possible. A T3 Pack-A-Punched weapon is also recommended.

Pack-A-Punch your weapons and buy every perk before using the Zakhaev exfil. Any items and upgrades on you will carry over to the instanced mission.

When you’re ready,head to the exfil location named “Defeat Zakhaev” on your map.It’ll be marked with a gold star, similar to the other instanced story missions. Hop on the helicopter when it arrives to start the mission.

Proceed To Zakhaev’s Facility

Upon landing, you will be tasked with entering a facility near the middle of the map.Many mercenaries will be guarding the entrance, so take this part slowly. A long-range weapon can be used to pick off the mercenaries from a safe distance. Past the shoreline are a few rigged proximity mines. Shooting the traps will blow them up.

Further into the compound, you will find a few inconspicuous shipping containers.These containers house T2 zombies, the same difficulty as the Medium Threat zone. They’re not too difficult to kill, but they can easily distract you from the mercenaries guarding the nearby facility.Back up, kill the zombies, then push into the facility.

Plant The Explosive Charges

The inside of the facility will be guarded by a small group of mercenaries.Two snipers will be positioned on the catwalks on the second floor,so be sure you take them out first. If you’re playing solo, we recommend youreach the rooftopfirst and fight the enemies from above. If you enter the ground floor, try to lure the zombies inside to distract the soldiers.

When the coast is clear, you’ll need to plant explosives on the enrichment device.Exit the facility when you’re doneto start the next objective. Beware that a small army of mercenaries will be waiting for you outside.

Get To The Neutralizer

Jensen’s Neutralizer device is on the western edge of the map, once again guarded by a small group of mercenaries.An ammo cache can be found inside a nearby warehouse, so now is a great time to restock on ammo. Clear out the soldiers, reload your weapons, and apply all of your armor plates.

A helicopter will spawn and attempt to kill your team.It behaves identically to the helicopters seen in Escort Contracts. You don’t need to destroy it; simply damage it until it hovers near the warehouse.

Defeat Orcus

A massive worm creature will erupt from the ground and destroy the helicopter.You must defeat Orcus to finish the mission.The creature might look intimidating at first glance, but it only has three ways of hurting you:

Beyond that, simply damage the boss with your weapons until it dies.The glowing purple segments are considered weakpointsand receive critical damage from all weapons. This damage is doubled if you’re using Deadshot Daiquiri, so any weapon with high critical damage will make short work of this boss.

Stick close to a building throughout this fight, as it will protect you from Orcus' laser attack. Shoot its weakpoints when you’re able to fight any zombies that spawn, and you should be able to slay this boss in a few minutes. The mission will end once Orcus is slain.
