Discover how to navigate the dangerous Metro facility in Dead Island 2 to find the Patient Lockbox Key. This guide covers combat strategies for the Inferno Crusher and how to claim the rare Electrocution Hunting Rifle.
Dead Island 2’s HELL-A is a playground of gore, grit, and high-tier loot, but some of the best gear is tucked away behind locked doors and elite enemies. If you’ve been roaming the subterranean depths of the Metro, you’ve likely stumbled upon a mysterious container that requires the Patient Lockbox Key.
In this guide, we’re breaking down the journey through the fire-damaged tunnels of the Metro to help you take down the specialized infected, secure the key, and claim the rare Electrocution Hunting Rifle. Whether you're a completionist or just looking for more firepower, here is everything you need to know.
Navigating the Subterranean Facility
Timestamp: [0: - :00]
The journey begins in the industrial corridors of the Metro facility. This area is characterized by its dark, atmospheric lighting and tight, claustrophobic hallways. Navigation here is just as much a challenge as the zombies themselves.
When exploring this initial section, keep your flashlight ready and your eyes peeled for resources. The game emphasizes environmental awareness; look for crates, scrap, and crafting materials tucked into corners. At this stage, you are primarily moving toward the deeper subway tunnels where the high-value targets reside. Always check your map frequently to ensure you aren't looping back into previously cleared rooms.
Facing the Heat: Subterranean Combat

As you transition into the fire-damaged subway tunnels, the difficulty spikes. You aren't just dealing with standard walkers anymore. This section of the walkthrough highlights intense combat sequences against specialized zombie variants, most notably the Inferno Crusher.
Tactical Tip: Using the Big Shot
In the video, the player utilizes the Big Shot, a legendary revolver that packs a massive punch. When facing an Inferno Crusher, distance is your best friend. The Big Shot’s explosive rounds are perfect for staggering these hulking brutes, preventing them from closing the gap and using their devastating ground-pound attacks.
If you find yourself in the subway tunnels, remember these combat rules:
- Aim for the head: Even with legendary weapons, precision saves ammo.
- Kite your enemies: Use the length of the tunnel to keep distance between you and the specialized infected.
- Watch for fire: The environment is fire-damaged, and standing in the wrong spot can drain your health faster than a zombie bite.
Hazardous Zone Entry and Electrified Water
Timestamp: [0: - :00]
Dead Island 2 is famous for its environmental hazards, and the Metro facility uses them to lethal effect. As you push deeper, you will encounter zones filled with electrified water. Stepping into these pools is a death sentence if you aren't careful.
To navigate this area successfully, you must use the environment to your advantage. Look for circuit breakers to jump-start or shut down power, or use your jumping mechanics to hop across dry surfaces. During this phase, you will also encounter the Derailed Patient, a specialized zombie variant who holds the key to the loot you're seeking.
Engaging the Derailed Patient requires a mix of melee and ranged tactics. Use the dodging mechanic to avoid their lunges, and then follow up with high-impact melee strikes to break their posture. Close-quarters combat here is risky, so ensure your health is topped off before engaging.
Securing the Lockbox Key and the Electrocution Hunting Rifle
Timestamp: [0: - :47]
Once the Derailed Patient is defeated, they will drop the Patient Lockbox Key. This is the moment you’ve been working toward. With the key in hand, you can head to the lockbox located within the facility.
The Prize: Electrocution Hunting Rifle
Unlocking the lockbox grants you the Electrocution Hunting Rifle. This rare weapon is a game-changer for mid-to-late-game content.
- Status Effect: It deals significant electrical damage, which can chain between enemies when they are standing in water or grouped close together.
- Range: As a hunting rifle, it provides excellent accuracy for taking out spitters and other ranged threats from a safe distance.
- Utility: It’s especially effective against wet zombies, making it a perfect companion for levels with burst pipes or rainy weather.
Actionable Insights for Metro Survival
To make your run through the Metro as smooth as possible, keep these takeaways in mind:
- Prioritize the Big Shot: If you have access to legendary revolvers, use them for the Inferno Crushers to save your primary rifle ammo for the Derailed Patient.
- Environmental Kills: Notice the pools of water and exposed wires? Lead zombies into these hazards to save weapon durability.
- Loot Everything: The Metro is a goldmine for high-end crafting parts. Don't rush to the boss; take the time to open every locker.
- Weapon Maintenance: Before entering the subterranean facility, ensure your weapons are fully repaired at a workbench. The density of specialized zombies in the Metro will chew through your durability quickly.
Conclusion
The Metro in Dead Island 2 is a gauntlet of fire and electricity, but the reward is well worth the risk. By following this guide, taking down the Derailed Patient, and securing the Patient Lockbox Key, you’ll add one of the most effective elemental weapons to your arsenal: the Electrocution Hunting Rifle.
