Killing Floor 3 perks tier list, listed

Here is a table showing all the perks that you can play in Killing Floor 3:
Tier | Perks |
---|---|
S Tier | Firebug |
A Tier | Commando, Ninja |
B Tier | Engineer, Sharpshooter |
C Tier | Medic |
S tier: Firebug

There’s nothing quite as satisfying as combining relentless gunfire with scorching flames to take down the hordes of Zed, and that’s exactly where Firebug shines. This perk excels at dishing out continuous area-of-effect damage with incendiary weapons and grenades that can clear the enemies in seconds.
She brings chaos and efficiency in equal measure, making it a top-tier choice for aggressive, high-impact players. If you’re stuck in the middle of hordes, consider using your Wildfire gadget, which clears the waves around you instantly. Most of her weapons have fire damage, making her less effective against Mire Zeds. However, she can easily nullify this weakness by using various weapons to counter it and relying on her teammates.
Her burn damage also stacks on enemies over time, making Firebug an ideal perk for melting bosses and finishing runs with ease.
A tier: Commando, Ninja

If you want a well-rounded perk that excels at almost everything they do, then you can choose the Commando. He’s known for using assault rifles in his amrory, which gives him versatility to support fire for every perk in the game, making it a great backup.
Like Firebug, he has an AOE clear gadget with Hellion, an autonomous flying drone that shoots the Zeds with acid shots, giving you easy headshots. You can trigger Zed Time easily while using it, making it easy for you to escape tricky situations or cover allies.
Ninja thrives in the thick of combat, wielding specialized melee weapons to take down Zeds with precision and agility. Unlike other perks that rely on quick knife kills, Ninja focuses on sustained close-range combat to trim enemy numbers efficiently.
His signature gadget, the Hebi-ken, allows for rapid repositioning, letting him control the pace of battle and strike where it hurts most. With his perks to reduce incoming damage and draw enemy attention, Ninja can serve as both a high-impact brawler and a durable distraction, giving teammates the space they need to clean up the horde. He also houses Electrical damage in his weapon and throwable, giving a team a diverse source of damage.
B tier: Engineer, Sharpshooter

An engineer is a fun utility pick that gives you access to free multikits to set up turrets, ziplines, and even armor up a few portions of the map to set up nicely for your team. The perk has an interesting gadget, Sonic Storm, which packs a serious punch to thin out the zed hordes in sticky situations. However, the Engineer’s reliance on shotguns means getting up close and personal with Zeds, often without strong self-defence capabilities. This makes the perk heavily dependent on teammates for covering fire, especially during chaotic waves.
A Sharpshooter can be lethal in the right hands, excelling at picking off high-priority targets with pinpoint accuracy. Specializing in headshots and dishing out heavy damage to the bosses, this perk rewards patience, precision, and smart positioning.
A skilled Sharpshooter can thin out tough enemies before they become a threat, making it a strong asset in the hands of a focused and experienced player. But that’s the downside as well. If you fail to hit your shots while not using your Cryo-grenade to freeze enemies, your team pays the price for it heavily, making it a high-risk strategy.
C-tier: Medic

While healing is essential to surviving the waves of Zeds, the Medic in Killing Floor 3 lacks the raw offensive power needed to stand out. Focused primarily on keeping the team alive, the Medic’s tools are great for sustaining while playing with squads, but fall short when it comes to clearing enemies quickly or dealing with bosses efficiently. Especially in the solo runs, his gadgets like Sanctum and tools become useless. Some players may find the Medic underwhelming compared to other perks because of his lack of offensive options.
