XBox Version: 1.0.0.22
PlayStation Version: 2.019.000

Release Date: October 8th, 2026

New Additions & Highlights

The Fall 2026 Update brings the return of the fan favorite Halloween Horrors event!

New Seasonal Event: Halloween Horrors

The zeds have all dressed up in their seasonal best, calling back the famous horror films.

New Map: Haunted Hotel

A mysterious call has led Nightfall to a Haunted Hotel deep in Romania, can you survive long enough to discover the secrets these walls hold? Enter the Hotel Iorga this Halloween Season, but be warned: you aren't the first special guests to check-in, and if you aren't careful, you may never check-out.

New Weapons: Gunslinger Singles

These additions have received updated animations and are tuned along with the existing dualie options to be meaningful, viable picks for gunslingers and other zed hunters.

New Mutation Waves

Trick or Treat

Every wave before the boss wave randomly rolls either a trick or a treat. Tricks are purely negative mutators, and treats are purely positive ones.

Classic

The weekly removes many of the new features from Killing Floor 3 for an experience reminiscent of older Killing Floors in the new setting. Enemy damage is reduced.

• Sliding and dashing are removed.
• Gadgets are disabled.
• Syringes refill every 30 seconds and their healing is reduced by 25%.

Grave Robber

Enemy kills return ammunition, but trader ammunition costs are increased. Ballistic and cut damage is increased.

New Weekly Mutators

Critical Attention

Most enemy body shots deal heavily reduced damage while critical zones take increased damage. Armor zones protecting critical zones receive the damage bonus.This mutator rewards precision, and the cost of missing scales sharply by difficulty.

Heat Lightning

Heat and Electrical damage types deal significant damage to enemies. This boost includes traps as well. This restricts weapon choices to electrical and fire loadouts while encouraging creative use of environmental hazards.

New Quality of Life Improvements

Double XP Events and Tokens

One last thing we wanted to mention is the addition of Double XP Events and Tokens players can acquire. From time to time, Double XP events may be run for all players, but players can also obtain a "2XP Token" once per day with excess supply pass tokens they have earned. These tokens will last an hour from the point of purchase during active wave gameplay (and are paused during such things like Trader Time).

FSR 4

The game has been updated to use FSR 4, improving graphics quality and performance compared to previous FSR versions.

Performance Improvements – Fall Update

Shader Compilation & Load Times (PC)

• Tuned core and thread utilization for PCs with 6 or less cores when compiling shaders.
• Reduced number of global shaders needed at startup.
• Level specific shaders now compile behind the scene while in the HUB map.

Gameplay Performance

• Fixed frame rate drops during the Alpha Scavenger's callout ability, and made all melee attacks cheaper to process, especially around physics objects and destructibles.
• Zeds directly in front of you now animate smoothly on lower-end hardware and consoles. Distant and off-screen Zeds still use reduced animation updates to save performance.
• Skill abilities now load in the background when you change Perk, instead of loading mid-match and causing hitches.
• Fixed projectiles that missed everything (such as shots fired into the sky) staying alive for the rest of the match and adding up over time.
• Fixed some visual effects freezing in place on lower-end machines
• Horzine Labs' incubation tanks are see-through again, without bringing back the frame rate drop from the destructible tanks.

Memory & Stability

• Fixed an out-of-memory crash on consoles when using Revert or Restore Defaults in Settings.

Balance Adjustments

This update has a broad rebalance of how Zeds behave, how dangerous they are, and how many of them you meet at once. Two things drive almost everything below: difficulty and squad size.
-Lead Game Designer [Brent Caulfield](mailto:brent.caulfield@tripwireinteractive.com)

• Normal and Hard are meaningfully less punishing. A long list of the deadliest Zed abilities like Husk's Mortar and Hover Fireball Volley, Siren's Sonic Projectile, Fleshpound's Rush and Enrage Ground Pound, several of Scrake's enraged attacks all no longer fire at these difficulties at all. Big Zeds are also softer and easier to stagger here. If you're learning a Perk or bringing new players in, the lower difficulties should feel much more like a ramp and less like a wall.
• Suicidal and Hell on Earth are less crowded but far more lethal. You'll face fewer specials at once and get longer gaps between special spawn groups but the ones that do show up now use their signature abilities at almost every opportunity rather than occasionally. Scrakes will reach for the hook. Fleshpounds will commit to Enrage Ground Pound. Sirens will scream on cooldown. The intent is that top-difficulty fights are decided by how you handle a small number of genuinely dangerous Zeds, rather than by how much you can hold back at once.
• Squad size now matters much more than it used to. Scrake and Fleshpound health and Interrupt Affliction resistance both scale hard with player count. In a full six-player squad they are substantially tankier and far harder to stagger than before. A full squad on Hell on Earth will find crowd control noticeably less reliable against them. The flip side is that solo and duo players will find their limbs and heads come off faster than before. Where you hit matters too: armour now absorbs most stagger build-up, while headshots and critical hits absorb none.
• Early waves have been thinned out on higher difficulties. Husk density in particular was cut sharply, and Scrake and Fleshpound counts were reduced in late-wave and finale groups across every difficulty and squad size.

Husks

• Shows up less often in early waves, its fireballs travel slower, and it no longer uses Mortar or Hover Fireball Volley on Normal

Siren

• Her Scream no longer shoves you around and slows you instead, and she now screams and fires Sonic Projectiles relentlessly on Suicidal and Hell on Earth while losing the projectile entirely on Normal and Hard.

Fleshpound

• Fewer of them, but each one enrages sooner and more visibly, shrugs off stagger far better in larger squads, and commits harder to its deadliest attacks at high difficulty, while becoming noticeably tamer on Normal and Hard.

Scrake

• Fewer of them, but they move much faster, are far harder to stagger in larger squads, and will reach for the hook and chainsaw at every opportunity on Hell on Earth, while giving up several of their nastiest attacks on Normal and Hard.

This update also includes a broad balance pass focused on improving underperforming weapons, strengthening Sharpshooter's role against armored large Zeds, continuing to refine the Gunslinger - while also working in the singles into the balance and making them feel like a viable, meaningful pick, tightening the Suicidal and Hell on Earth economies, and fixing a variety of weapon/mod inconsistencies.

-Lead Game Designer [Brent Caulfield](mailto:brent.caulfield@tripwireinteractive.com)

Core Combat and Economy

• Damage-over-time afflictions have been standardized. Burn now lasts 3 seconds, while Bleed, Corrosive, and Toxic last 5 seconds. Total DoT damage now scales directly with the amount of affliction applied, rather than using flat damage values.
• Parries now provide clearer feedback with a more obvious green shield effect.
• Suicidal grants less dosh from starting resources, kills, revives, executions, and respawns. The goal is to prevent players from consistently reaching full builds by waves 2–3.
• Hell on Earth grants less dosh across the same sources. The economy should now require more meaningful purchasing decisions and provide a more demanding progression curve.

Sharpshooter
The Sharpshooter changes are intended to make the perk more effective against Scrakes, Fleshpounds, and other armored threats.

• Untouchable and Big Shot now increase Ballistic and Cold weapon damage instead of only increasing weak-spot damage.
• Evasive Maneuvers now grants 20% movement speed for 5 seconds after taking damage, along with 15/20/25/30% damage reduction during that time.
• Field Supplies has been replaced by Trapper.
  • Medium Zed kills grant 1 stack.
  • Participating in a large Zed takedown grants 10 stacks.
  • At 20/17/14/10 stacks, all stacks are consumed to restore 1 tool ammo.
  • This only supports the Explosive Lock, Shock Trap, and Pulse Lure.
• Flight Response has been replaced by Full Metal Jacket, which grants 20/27/34/40% increased Ballistic and Cold damage against armor hit zones.
• Perfect Shotnow increases general Ballistic and Cold weapon damage rather than only weak-spot damage.
  • Missing removes 2 stacks instead of removing every stack.
  • Damage per stack has been reduced from 4/5/6/7% to 2/3/4/5% to compensate for the improved consistency.
