Tier List Overview
In The Outlast Trials, survival is not determined by how fast you can pull a trigger, but by how effectively you can manipulate your environment, manage your inventory, and outsmart the relentless Ex-Pops chasing you. Because the game does not feature traditional "characters" with unique base stats, the true measure of a player's build lies in their chosen Presets (Perks), Upgrades, and the Tools/Weapons they bring into the facility.
This tier list ranks the absolute best builds and loadouts in The Outlast Trials. Rather than focusing on a single healing or stealth focus, this list evaluates the meta based on efficiency in completing Grade 3 (and above) missions, optimizing Program Score, and facilitating smooth team synergy. A top-tier build in this game reduces friction, minimizes the need to scavenge for basic supplies, and allows a team to push through punishing environments without relying on lucky Loot Container spawns. Whether you are a solo player looking to maximize your score or a dedicated team player keeping your squad alive, understanding which combinations rise above the rest is crucial for ascending the ranks.
S Tier
S Tier builds are the undisputed kings of the current meta. These loadouts fundamentally break the game's core loop of scavenging and running, allowing teams to bypass major threats or completely ignore the exhaustion mechanic. If you want to guarantee completion on the hardest difficulties with minimal stress, these are the builds you and your team should be running.
- The Biogenesis Battery (Healer / Support)
This build turns a single player into an immovable pillar of health for the entire team. The core of this build relies on the Biogenesis perk combined with Slower Drain and Prolonged Transmission upgrades. Biogenesis heals all teammates within a specific radius, but it normally drains your health incredibly fast. By stacking Slower Drain upgrades, you reduce the self-damage to a trickle, while Prolonged Transmission ensures the healing radius stays active even when you are dodging enemies or hiding. Paired with the Syrettes tool (upgraded with Increased Duration and Extra Charges) and the Bonesaw weapon (which heals you on kill), this build allows a team to completely ignore bandages and first aid kits. In a game where inventory space is your most valuable asset, freeing up three to four slots per player because you don't need healing items makes this build an automatic S Tier inclusion for any serious squad.
- The Invisible Ghost (Stealth / Saboteur)
Stealth in The Outlast Trials is notoriously difficult due to the hyper-awareness of the Ex-Pops, but the Invisible Ghost build makes you practically untouchable. This build centers around the Disguise preset, heavily upgraded with Extended Duration and Stamina Preservation. The defining perk here is Adrenaline, which prevents stamina from draining while you are being chased—but when flipped in the context of a stealth build, it allows you to sprint silently between hiding spots without leaving a massive trail of sweat or footprints. You pair this with the Stun Baton (upgraded with Silent Strike) and either the Hypnotic or Incendiary tool. You become the ultimate saboteur: you can walk directly into a room with a sleeping Prime Asset, rig the objective, and walk out without ever triggering an alarm. For solo players attempting high-tier missions where taking a single hit can spell doom, this is the most reliable path to victory.
A Tier
A Tier builds are exceptionally strong, highly reliable, and form the backbone of most random matchmaking groups. They might lack the sheer game-warping power of S Tier builds, but they are incredibly forgiving and excel at turning chaotic situations into manageable ones. These are the workhorses of the facility.
- The Battery Blitz (Melee / Aggro)
If your team lacks a Biogenesis healer, the Battery Blitz is the best alternative for self-sustainability. This build maximizes the Battery preset, focusing on gaining health back through aggression. Using perks like Life Drain alongside a fully upgraded Bonesaw and Cattle Prod, this build allows you to wade into groups of Grunts and Whistleblowers. Every time you strike a blinded or stunned enemy, you regenerate a portion of your health. The reason this sits in A Tier instead of S is because it requires you to be in extreme close quarters, which inherently increases the risk of taking burst damage from elite enemies like Big Grunts or Tailcoats. However, in the hands of a player who knows enemy attack patterns, this build provides infinite sustain and incredible crowd control.
- The Lockpicker's Dream (Utility / Scavenger)
Money and Rig upgrades are the true progression systems in The Outlast Trials. The Lockpicker build maximizes the Scavenger preset, utilizing perks that increase the drop rate of high-value items and reduce the time it takes to complete environmental puzzles. The absolute star of this build is the Lockpicks tool, upgraded with the Master Lockpick (which opens locks instantly) and extra charges. Furthermore, taking perks that increase your Rig capacity allows this player to hoard valuable items like X-Paths, Antidotes, and Premium Charge Bricks. This build sits comfortably in A Tier because, while it doesn't directly kill enemies or heal the team, a good Lockpicker can shave several minutes off a mission time by bypassing tedious key-card hunts and ensuring the team has enough consumables to survive the final exit sequence.
- The Cryo-Control Specialist (Crowd Control)
Using the Cryogenic preset, this build turns the Cryo-Canister into the best crowd-control tool in the game. By upgrading the canister with Expanded Radius and Lingering Frost, you can freeze entire hallways of pursuing enemies. The key synergy here is pairing the freeze effect with melee weapons—frozen enemies take drastically increased melee damage. You can throw a canister, freeze a group of enemies, and instantly execute them with a charged heavy attack from a sledgehammer. It drops to A Tier simply because it requires precise positioning and can sometimes inadvertently freeze your own teammates if they are running away from the same horde you are trying to freeze.
B Tier
B Tier options are decent, highly fun to play, and perfectly viable for completing Grade 1 and Grade 2 missions. However, as the difficulty scales up and enemy damage increases, these builds start to show their flaws. They usually require too many upgrades to function properly or are outclassed by the options in the tiers above.
- The Night Vision Sniper (Ranged / Recon)
This build attempts to play The Outlast Trials like a traditional shooter, utilizing the Night Vision preset alongside a highly upgraded Crossbow or Spear Gun. The concept is strong: stay far away from enemies, shoot them in the head, and remain safe. In practice, however, ranged weapons in this game lack the staggering power of melee weapons. If you miss a shot with the Crossbow, the reload time is so punishing that enemies will close the gap and strike you. Furthermore, ammo is incredibly scarce, meaning you cannot rely solely on ranged attacks to clear objectives. It is a fun playstyle, but objectively inferior to a well-built melee or stealth loadout.
- The Blitz Athlete (Speed Runner)
The Blitz preset is inherently fun because it lets you sprint at ludicrous speeds. This build stacks stamina regeneration perks and utilizes tools like the Sprint Boost injection to literally run past enemies before they can react. The problem? The Outlast Trials is a puzzle game at its core. You cannot sprint through a room that requires you to fix three generators, pull two levers, and insert a cassette tape. The Blitz build excels at running to the exit once the objectives are done, but it contributes very little to the actual grunt work of the mission. It is a B Tier build because it is a one-trick pony that falters when a team actually needs help completing interactive tasks under heavy pressure.
- The Trap Master (Environmental Killer)
This build focuses on using environmental hazards—like pushing enemies into grinders, using electro-shock panels, or dropping barrels on their heads. While satisfying, relying on the environment is highly inconsistent. Map layouts change, and enemy pathing can be unpredictable. You will often spend minutes trying to bait an enemy into a trap, only for them to bug out or walk around it. It is a highly situational strategy that works beautifully in specific map sections (like the Polyclinic) but falls apart entirely in open-air environments.
C Tier
C Tier builds are either fundamentally flawed, heavily outclassed by other options, or rely on mechanics that are simply too unreliable in the game's current state. You should avoid bringing these into Grade 3 missions, as they will actively hinder your team's chances of success.
- The Slapdash Brawler (Unupgraded Melee)
This is the default state most new players find themselves in: running the base Brawler preset with a completely unupgraded Baton or Lead Pipe. Without upgrades like Shocking Strikes or Stun Duration, basic melee weapons take far too many hits to kill basic Grunts. Furthermore, without the life-steal perks found in the Battery preset, trading blows with enemies will quickly deplete your health. In a game where taking damage causes your vision to blur and your character to pant loudly, a pure, unupgraded melee build without sustain is a liability.
- The Pure Chemist (Poison Focus)
The Chemistry preset, when focused entirely on poison damage (using poison syringes and poison-based perks), is painfully slow. Poison in The Outlast Trials acts as a damage-over-time effect, but enemies do not die fast enough. A poisoned Grunt will still have enough health to run across the room and hit you before the poison takes them down. When compared to the instant incapacitation of a Cattle Prod or the raw burst damage of a Sledgehammer, poison feels incredibly weak. It has minor utility in slowing enemies down, but dedicating an entire build to it is a waste of potential.
- The Pure Medic (No Combat Utility)
While the S Tier Biogenesis build is a form of healing, a "Pure Medic" build that focuses solely on crafting and handing out Syrettes without any offensive upgrades or Biogenesis is a trap. If you are not running Biogenesis, you have to manually inject teammates. In the middle of a chase, standing still to inject a teammate is incredibly dangerous and often results in both of you taking damage. Furthermore, without any offensive tools, if you get separated from your team, you are completely defenseless. Healing is important, but a player must always be able to contribute to crowd control or objective completion independently.
How to Use This Tier List
Understanding this tier list requires a bit of context regarding how The Outlast Trials operates as a live-service game. First and foremost, team composition matters more than individual power. A team consisting of one Invisible Ghost, one Biogenesis Battery, one Cryo-Control Specialist, and one Lockpicker will have a significantly easier time than a team of four Battery Blitz players. Synergy is key; let the stealth player open doors, let the cryo player freeze the room, let the healer keep everyone alive, and let the scavenger collect the loot.
It is also important to remember that Upgrades make the build. A tool or preset listed in S Tier will perform like a C Tier option if you do not have the proper MK upgrades unlocked at the Loading Bay. Do not attempt to run the Invisible Ghost build without Extended Duration upgrades, or you will find yourself exposed in the middle of a room full of enemies. Progression in this game is a marathon, and you should focus on maxing out the tools associated with your desired playstyle before moving on to experiment with others.
Finally, keep an eye on Red Barrels updates. The developers at Red Barrels frequently tweak enemy aggression, stamina costs, and item spawn rates. A patch that slightly reduces the self-damage of Biogenesis could push it into an entirely different stratosphere of balance, while a patch that increases the vision range of enemies could heavily nerf pure stealth builds. Play what is fun for you, but when the lights go out and the Prime Assets start hunting, trusting the S and A tier loadouts is the safest way to ensure you make it out of the facility with your sanity intact.
