Walkthrough

“The Oldest House is alive. It bleeds anomalies. And you Firebreaker are its containment.”

Step into the shoes of a Firebreaker, the Federal Bureau of Control’s most daring first‑response unit. Whether you’re streaming your first drop-in or rallying a crew of seasoned agents, this walkthrough will guide you through FBC: Firebreak’s core mechanics, Job design, and progression loops—arming you with both story and strategy to turn every crisis into a triumph.

Prologue: The Siege of the Oldest House

Six years have passed since the Hiss invaded the Bureau’s extradimensional headquarters. Hallways twist. Reality fractures. The Oldest House stands locked down, a labyrinth of paranatural horrors. As a Firebreaker,  you’re a crisis specialist, entering danger zones to restore order, contain chaos, and reclaim control.

Walkthrough Summary:

  • Clearance & Threat Levels: Every Job’s difficulty is customized by two key settings. The Threat Level controls combat intensity (enemy toughness and swarm size and makeup). The Clearance Level controls mission length. “Each Job is split into distinct zones, escalating in complexity, and your chosen Clearance Level designates how many of those zones you’ll need to get through”. (In short: low Threat/low Clearance = short, easier jobs; high Threat/high Clearance = longer, harder jobs with bigger rewards.

  • Corruption Level: A third setting, Corruption Level, adds modifiers or hazards to the mission (for example, Corrupted Items or changing the location of showers and ammo stations). Together with Threat and Clearance, Corruption lets you fine-tune each session’s challenge. You can mix and match these settings – for example, a short “surgical” run would be Clearance 1 with low Threat, whereas a “long and brutal” run might use high Clearance, high Threat, and maximum Corruption.

  • Perks and Research: As you play, you collect Lost Assets and Research Samples (earned by clearing special Corrupted Items in Jobs), which let you unlock and upgrade Firebreaker Perks. The Perk system has three levels: Level 1 (minor effect), Level 2 (stronger), and Level 3 (strongest and shared with your crew). Equipping higher-level perks costs more Perk slots, so choose carefully. Perks can dramatically change gameplay, so invest in Samples to unlock new Perks and boost existing ones as you progress.

  • Weapons & Gear: Weapons and gear can be upgraded over time. Guns, grenades, and tools are upgradable to more powerful versions. You upgrade them by earning and collecting Lost Assets from the Jobs, which you then use in Requisitions to unlock better gear. Your Crisis Kit and loadout evolve as you unlock better devices, new guns, and equipment, making later Jobs more manageable.

  • Requisitions and Lost Assets: Progression is free-form. Completing Jobs grants an in-game currency called Lost Assets. Use Lost Assets to unlock items from Requisitions, which are collections of weapons, equipment, armor, and cosmetics. Standard Requisitions (free for all) lets you permanently unlock gear of your choice using Lost Assets.

    (For example: you might unlock a new submachine gun, a grenade, or an armor piece you like.) Classified Requisitions are premium cosmetic-only packs bought with real money; they do not affect gameplay. Crucially, all Requisition items remain available permanently, and you can progress multiple Requisitions at once at your own pace. In short, there are no loot boxes or time gates, just play Jobs, earn Lost Assets, and choose exactly which weapons or items to unlock.

Player Progression & Customization: You advance Firebreaker power by completing Jobs and spending your rewards:

  • Complete Jobs: Play and finish Jobs to earn Lost Assets and loot. Finishing objectives and safely extracting awards more currency.

  • Unlock Gear: Spend Lost Assets in Requisitions to permanently unlock new weapons, armor, equipment, and cosmetic items. Unlock what you want, the system is non-linear and choice-driven.

  • Upgrade Weapons: Invest in weapon upgrades. Improved guns will deal more damage and have better stats.

  • Upgrade Perks: Use Lost Assets and Research Samples (from neutralizing Corrupted Items in Jobs) to unlock or upgrade your Perks. Higher-level Perks give stronger bonuses and, at Level 3, benefit the entire team.

  • Refine Kits: As you acquire new tools and Perks, try different Crisis Kit combinations to find synergies. The Jump, Fix, and Splash Kits each excel in different tasks (mobility/electric attacks, repair/crowd-control, and water/healing, respectively), so coordinate kits among teammates for the best results.

Note: By continually playing Jobs, unlocking gear, and upgrading abilities, your team grows stronger.

Core Gameplay Systems

Role and Objective as a Firebreaker

FBC: Firebreak is a 3-player cooperative FPS set in the paranatural Control universe. You and two teammates deploy as Firebreakers to clear each crisis mission (called a Job).

Before a Job, you choose a Crisis Kit (preset loadout), a grenade, and a primary weapon. Each Crisis Kit (Jump, Fix, or Splash) comes with a specialized Tool, Improvised Device, and Altered Augment tailored to a role (e.g,. mobility/electric, repair/crowd-control, or water/healing).

Weapons, grenades, and Perks are not locked to any Kit – you can mix and match your gear and perks however you like before each mission. These Jobs operate similarly to game modes and are customizable based on three parameters:

Clearance Level - Determines the length of the session, allowing players to tailor the Job duration. Each Job is split into distinct zones, escalating in complexity, and your chosen Clearance Level designates how many of those zones you’ll need to get through.

  • Zone 1: Introductory level with manageable threats.

  • Zone 2: Increased difficulty with more complex objectives.

  • Zone 3: Confront the Heart of the Anomaly in a high-stakes environment with formidable enemies and challenges.

Note: You must complete Zone 1 to unlock Zone 2, and both Zones 1 and 2 to access Zone 3. Once all Zones are unlocked, you can choose your Clearance Level:

  • Clearance Level 1: Play Zone 1 only.

  • Clearance Level 2: Play Zones 1 and 2.

  • Clearance Level 3: Tackle all three Zones in a single run.

Clearance Level determines the length and depth of your mission.

Threat - Dictates the intensity of combat encounters (enemy toughness, aggression, and swarm size).

  • Ranges from Easy → Extreme, shaping enemy count, aggressiveness, and elite variants.

  • Higher Threat Levels introduce more enemies, aggressive behaviors, and unexpected challenges, but also offer better rewards.

Corruption: Paranatural Chaos - Corruption adds unpredictable elements to your mission, such as environmental changes and Corrupted Items that alter gameplay mechanics. This layer of complexity is available when running a full Job at Clearance Level 3.

  • Spawns unpredictable Corrupted Items from the gravity‑warping Wolff Globe to the nerve-racking Traffic Light.

Examples of Corrupted Items:

  • Wolff Globe: Alters gravity, affecting movement.

  • Traffic Light: If you move when the light on it is red, you take a lot of damage.

Tip: Removing Corrupted Items using a Neutralizer (can be found in Ammo Stations and Shelters) can earn you Research Samples, a rare currency for unlocking and upgrading Perks.

Choosing Crisis Kits and Loadouts

Before a job starts, players select one of three Crisis Kits, each offering specialized gear that defines the player’s role:

Splash Kit: Focuses on fire extinguishing and removing harmful conditions from teammates, emphasizing support and utility.

Jump Kit: Oriented toward mobility and electrical device interaction, enabling faster traversal and mission efficiency.

Fix Kit: Concentrates on repelling enemies and repairing machinery, providing frontline defense and operational support.

Each crisis kit comes bundled with a unique set of specialized gear, plus the option to customize guns, grenades, and perks that synergize with the kit’s strengths.

“No two Firebreakers are the same. Mix and match to suit your style or complement your crew.”

Perks

Perks are unlockable enhancements through research that give you passive abilities. Here are examples:

  • Electric Rounds - Bullets have a chance to inflict shock

  • Rapid Response - Manual repairing, charging, and extinguishing is faster

  • Iron Liver - More resistant to harmful condition build up

Tip: Perks are stackable, and equipping three allows their effects to be shared with your crew.

Requisitions

Requisitions are unlockable sets containing weapons, equipment, and cosmetics. They come in two types:

  • Operational Essentials: Nine pages of Unlockable Standard Requisitions require Lost Assets to advance.

  • Classified Requisitions: Cosmetic-only items are available to purchase with real money.

Note: All Requisitions are permanently available and can be unlocked in any order, with progress tracked simultaneously across multiple Requisitions.

Job Progression and Zone Management

Once the team chooses kits and enters the job location via a service elevator, they must clear several crisis zones determined by the clearance level. To progress, players complete objectives unique to each zone, using their tools and gear efficiently. Examples include:

  • Repairing broken machines like the Shower: This machine is crucial as it heals teammates and removes harmful conditions.
  • Charging batteries such as those powering the ammo station: This accelerates resupply, keeping players stocked on ammunition.
  • Dousing flames: Flames can buff enemies and even damage teammates, so extinguishing fires directly impacts combat conditions.

  • Combat Waves:

    • Hiss respond dynamically, clearing objectives triggers increasingly aggressive assaults.

    • Elite Variants guard key chokepoints; team coordination and perk synergy are your lifelines.

Note: If players lack the proper tools, clearing objectives becomes slower and riskier, highlighting the significance of proper kit selection and preparation. After completing all objectives, Firebreaks open containment doors to push deeper into the crisis.

Escalating Combat and Tactical Gameplay

Completing crisis zones provokes an increasingly aggressive response from the Hiss, attracting waves of enemies, including challenging elite variants that lock down the job site until eliminated.

Key combat mechanics include:

  • Team Synergy via Resonance Shields: When Firebreaks stay grouped, their resonance shields amplify, providing both defense and synergistic perk effects across teammates.
  • Upgradeable Weapons and Grenades: These offer straightforward damage to Hiss forces, with tools adding versatile combat functions like stunning, knockback, or emergency escapes.
  • Kit-specific Altered Augments: Each Crisis Kit features an extremely potent and volatile Altered Item called an Altered Augment. These items charge over time and deliver massive bursts of combat power, but require careful management, as reckless use can harm the player and teammates.

Corruption Mechanics and Their Impact on Gameplay

When players enable the Corruption feature during jobs, they encounter uncontrollable Altered Items known as Corrupted Items. These introduce significant gameplay modifications with unpredictable effects that add complexity and chaos to missions. Examples include:

  • Exploding corpses on death.
  • Reduced gravity environments.
  • Rules that limit player movement, such as not crossing streets at certain times.

Note: Corrupted items are immune to traditional damage like bullets or explosions, but can be temporarily neutralized by finding rare black rock neutralizers scattered throughout the map.

Evacuation Phase and Decision-Making

Upon completing a Job’s final objective, an evacuation event is triggered. A massive Hiss swarm descends on the site, and players must return safely to the service elevator to extract. This phase tests player coordination, positioning, and time management. Players may face crucial decisions, such as:

  • Whether to attempt rescuing downed teammates.
  • Choosing when to press forward or retreat to secure extraction.

The tension and risk heighten as failure to escape means potentially losing progress and resources.

Progression and Customization at Firebreak HQ

After successful evacuation, players return to the Firebreak HQ to reap the rewards of their endeavors. Collected resources can be spent on:

  • Unlocking and upgrading equipment and perks, enhancing abilities and combat effectiveness.
  • Acquiring cosmetic items for character customization, allowing individual expression.

This hub area supports ongoing player growth, motivation, and continued engagement.
