Zombie Army 4: Dead War’s sixth campaign is called Molten Nightmare. From Genoa, the hero travels to Naples in pursuit of a cultist who has stolen Schweiger’s data. A new Hell Tower has also risen, causing Mt. Vesuvius to erupt. Here’s everything you need to know to complete Molten Nightmare and find all the collectibles.
Chapter 1: Come Hell Or High Lava Walkthrough
The campaign begins with you on the heels of a traitorous resistance fighter. You are in the safe room located on the edge of a town. Take your time to gather some supplies and upgrade your weapons, before making your way into the town.

When you leave the safe room, go forward, passing under the bridge, and head up the stairs. At the top, turn right and follow the railing around. An armored zombie will burst through a door here, so kill that before you continue.
With the armored zombie dead, continue until you come to a gap in the railing. Jump across the gap to land on a ledge outside a window. Vault through the window to find a document on a bed.

Follow the Cultist’s trail to the clifftop, where you will be ambushed by the dead. Make your way forward through a destroyed building. On the other side, you will find a comic inside a small room.
Continue following the cultist’s trail. A blood seal will block a gate, so stock up on ammo and kill the zombies that spawn in. There are lots of explosives around, so use these to deal most of the damage. Proceed further, jumping across the lava and making your way to the gate entrance.

As you pass through the gate entrance, a friendly resistance fighter will request your help to extinguish the fires. Your objective will change to repair the water pump, but turn right and enter the building next to the gate for now. Head upstairs and go out onto the balcony where the NPC is standing. There is another door up here. In the doorway, you’ll find an upgrade kit.

Jump between the destroyed buildings and make your way up the zombie-infested street to the safe room, completing Chapter 1: Come Hell Or High Lava.
Chapter 2: Hot On The Trail
Resupply in the safe room and then make your way out into the next area to confront the cultist. As you leave the safe room, you will see that the door ahead is electrified, preventing you from moving through.
Turn back and make your way around the railing to find a vantage point from which you can shoot the fuse box. The fuse box will explode, opening the door and killing the cultist. Approach the body to retrieve Schweiger’s data, and then go through the door to your left.

Turn away from the upgrade kit and walk in the opposite direction. You will see a comic on the edge of a rowboat storage unit.
Hot On The Trail Heroic Action
Get on the boat and speak with the captain. Help defend the boat from an incoming wave of zombies, and then pick up the satchel charge and head back off the boat. Follow the objective and plant the explosives to free Terry. Before you head into the safe room, escort Terry back to the boat, killing any enemies along the way, to complete the Heroic Action.
With Terry safe on the boat, go to the safe room to complete Chapter 2: Hot On The Trail.
Chapter 3: Night On The Town Walkthrough
Start Chapter 3 by grabbing some more ammo and explosives before leaving the safe room. Make your way through the town until you reach the blood fountain. Interact with the fountain and fill it by killing zombies in the marked ritual circle.

When the fountain is full, continue following the objective until you pass through a bar. You will see a zombie hand dancing on the bar.

Follow your objective into the Memorial Garden. As you enter, stay close to the right side and keep moving a little further forward. You will see a crypt entrance nearby. Head inside and turn right to find an upgrade kit within the catacombs.
Continue through the Memorial Garden until a blood seal appears. Clear the area of zombies and make your way down into another crypt. You will find a lever inside, which will open the door to the safe room, completing Chapter 3: Night On The Town.
Chapter 4: The Final Hell Tower Walkthrough
Gather some supplies in the safe room, and then proceed through the exit.

Go up the stairs and along the walkway, following the objective towards the abandoned explosives. As you approach the corner, four armored zombies will burst through a door. Kill them and go inside to find an upgrade kit hidden in the corner.
Take the abandoned explosives and plant them at the foot of the Hell Tower. Hitler will order more zombies to attack you, triggering a large battle against hordes of zombies. The easiest way to survive this battle is to climb back up to where you found the explosives and use the turrets to whittle through the zombies.
When the hordes have been defeated, a gate will open on the other side of the castle, leading to another abandoned explosive. Plant it at the Hell Tower to cause even more zombies to rise up.
Fight through the hordes using the explosives scattered around the central courtyard until the main exit opens. Run through to escape the explosion as the Hell Tower crashes down behind you, completing the Molten Nightmare campaign.
