Surviving high-difficulty waves in Peak Development Studios' hit wave shooter requires preparation, awareness, and top-tier loadouts. If you want to withstand heavy blows from elite infected, unlocking the Those Who Remain juggernaut perk is one of the most impactful defensive milestones you can achieve. Understanding how the Those Who Remain juggernaut perk operates can completely alter your frontline survivability, turning fragile skirmishes into controlled defenses.
Whether you are pushing through late endless runs or braving Hardcore mode, staying alive when surrounded by mutated hordes takes precedence over everything else. In this comprehensive breakdown, we explore everything you need to know about the Juggernaut skill, including equipment mechanics, level requirements, gear replacement thresholds, and survival strategies.
Overview and Unlock Requirements
In the perk progression system, perks function as passive benefits and loadout augments designed to improve player survivability, combat efficiency, and barricade durability. Players start selecting perks once they hit level 10, gaining access to three perk slots by default. A fourth slot can be obtained through the Extra Perk gamepass.
The perk roster divides into three primary classes:
- Survivalist: Enhances baseline player performance, medical efficiency, and mobility.
- Craftsman: Typically focused on bolstering fortification construction speed, utility efficiency, and barricade stats.
- Marksman: Improves gun handling, reload speed, accuracy, and shooting mechanics.
Every several levels, three new skills unlock across these categories until reaching the current progression cap at level 100. The Juggernaut perk represents the ultimate milestone in the Craftsman class. Unlocked at level 100 alongside Guardian Angel (Survivalist) and Overwatch (Marksman), Juggernaut demands dedication to unlock.
Unlike every other Craftsman option—such as Fortifier, Carpenter, or Efficiency—Juggernaut does not alter your fortification placement speed, barricade durability, or wire capacity. Instead, it alters your personal defensive kit, converting you into an armored anchor on the battlefield.
Makeshift Armor and Gas Mask Mechanics
Equipping the Juggernaut skill gives players a substantial defensive loadout right at spawn. The in-game description notes: "Spawn in with a full set of makeshift armor. This new armor is twice as durable as regular armor."
Understanding the exact mechanical properties of this kit is essential for keeping it intact:
Makeshift Armor Durability and HUD Changes
When spawning into a wave with the perk equipped, the survivor wears a full set of makeshift armor. On the user interface, your standard blue armor bar turns orange to signal that makeshift plating is active.
Because makeshift armor has double the durability of regular Body Armor, it absorbs extensive direct physical damage from basic and special infected before depleting. While wearing this armor set, your character's standard cosmetic accessories are hidden, reappearing only when the suit breaks or is replaced.
The 15% Replacement Rule
In prolonged skirmishes, even reinforced plating will take critical damage. Following a major balance update, survivors wearing makeshift armor are allowed to pick up and equip standard Body Armor once the makeshift armor's durability drops to 15% or below.
This threshold mechanic prevents you from wasting fresh body armor while your high-grade armor is still mostly functional, while ensuring you do not get caught with shattered defense mid-wave.
Built-in Gas Mask Protection
Following the July 2026 balance patch, the perk now provides a Gas Mask alongside the armor set upon spawn. Searching map interiors for loose Gas Masks can expose players to ambush risks in dark corridors. Having one instantly equipped grants complete immunity to lingering toxic spore gases emitted by detonated Bursters and lobbed spore clusters.
Equipment Summary
| Attribute | Makeshift Armor (Juggernaut) | Standard Body Armor |
|---|---|---|
| Durability Multiplier | 2x Standard Durability | 1x Standard Durability |
| HUD Indicator | Orange Armor Bar | Blue Armor Bar |
| Spawn Bonus | Includes Gas Mask | None (Looted in-match) |
| Cosmetic Effect | Temporarily hides accessories | Standard avatar appearance |
| Replacement Rule | Replaceable at 15% durability or less | Replaceable upon full destruction |
| Revival Retention | Lost on death; does not respawn on revive | Lost on death |
Strategic Frontline Survival with the Juggernaut Perk
Equipping the Those Who Remain juggernaut perk drastically shifts how you position during horde encounters. However, doubled durability does not mean invulnerability. Maintaining correct positioning is necessary to preserve your defense for emergency scenarios.
Guarding Against Swarms
Makeshift armor excels at soaking glancing hits and close-quarter strikes from Sprinters, Civilians, and Riot infected during high-density waves. When holding tight chokepoints or narrow doors, a stray claw swipe will not decimate your actual health pool.
Nevertheless, taking sustained group damage strips durability at a rapid rate. Keeping distance, backpedaling, and pairing your bulk with defensive crowd-control tools—such as Barbed Wire and Clap Bombs—ensures your orange bar remains intact for later waves.
Countering Toxic Explosions
Bursters and gaseous threats present a lethal hazard in closed spaces. Because the Those Who Remain juggernaut perk comes equipped with a Gas Mask, you are completely shielded from lingering environmental spore gases. You can safely clear infected near lingering clouds without taking continuous ticking damage every half second.
Revival Restrictions to Keep in Mind
A critical mechanical limitation reported in player guides and documented on the official wiki involves player downs. If you fall in combat and get revived by a teammate, you do not respawn with or retain your makeshift armor and Gas Mask.
Losing your suit mid-wave removes your protective buffer entirely until the next match deployment, requiring you to scavenge standard Body Armor and Gas Masks to rebuild your defensive safety net.
Facing the Juggernaut Infected
Beyond player skills, survivors regularly encounter the imposing Juggernaut Infected on high-tier waves in Classic and Hardcore modes. This special infected features high durability, a glowing red silhouette visible through walls, and heavy frontal armor that completely resists bullet-based weapons and melee attacks.
Running the Those Who Remain juggernaut perk provides a vital layer of defense when these mutated juggernauts enter the battlefield:
- Mitigating High-Impact Claws: The Juggernaut Infected deals heavy claw strikes that trigger severe screen flinch. Makeshift armor can absorb these strikes, giving you the necessary recovery window to reposition.
- Surviving Charge Attacks: When a Juggernaut Infected initiates its charging rush, making contact can instantly kill or severely maim unprotected survivors. Your doubled armor acts as a buffer if you fail to execute a sharp perpendicular dodge.
- Understanding Spore Vulnerabilities: While your provided Gas Mask negates the lingering spore gas clouds, direct hits from lobbed spore clusters bypass armor entirely. You must remain mobile and avoid standing directly in the cluster's impact radius.
- Exploiting Frontal Resistances: While the Juggernaut Infected ignores frontal bullet hits, players can bypass its armor using incendiary and explosive tools like Molotovs, Frag Grenades, the RPG-7, the Flamethrower, or the M320. Alternatively, coordinate with teammates to flank its unarmored back with high-firepower weapons like the MG 42.
Craftsman Class Progression and Perk Synergies
While Juggernaut stands out due to its pure combat-oriented defense, exploring where it sits in the broader Craftsman progression helps you plan your road to level 100.
| Level Unlock | Survivalist Perk | Craftsman Perk | Marksman Perk |
|---|---|---|---|
| Level 10 | Hardened Sight | Play Maker | Dexterous |
| Level 20 | Bruiser | Efficiency | Trigger Finger |
| Level 30 | Medic | Enhanced Electronics | Eagle Eyes |
| Level 45 | Caffeinated | Fortifier | Heavy Hitter |
| Level 60 | Adrenaline Rush | Pyrotechnic | Steady Hand |
| Level 85 | Speed Demon | Carpenter | Brisk |
| Level 100 | Guardian Angel | Juggernaut | Overwatch |
For players who purchase the Extra Perk gamepass, combining the Those Who Remain juggernaut perk with high-tier mobility skills like Speed Demon or utility perks creates a versatile survivor build capable of anchoring defensive setups without sacrificing rapid repositioning.
