Weekly Outbreaks

The Weekly Outbreaks in Killing Floor 2 are the special variations of the normal Survival Mode with specific mutator-a-like twists that modify certain gameplay elements making the game more challenging or forcing players to pickup specific strategies and loadouts in order to survive. There are currently 16 possible Outbreaks, with one available each week. Outbreak changes over on tuesday evenings (US time). Completing a Weekly Outbreak will earn players cosmetic rewards and 500,000 Vosh (cosmetic in-game currency) which is enough to acquire one Vault Crate that contains player accessories and weapon skins to customize your character.

Original 8 Weekly Outbreaks (from Boom to Beefcake) were added in the game on June 13, 2017, as a part of the Summer Sideshow update. Since the 2021's Dystopian Devastation developer team had begun adding more Outbreaks, free of charge, with every next major seasonal update.

...that must hurt their necks.

Gameplay specifics

• Enlarged head size: ZEDs and players have bigger heads. ZEDs have more health and only die when their body health is depleted.
• Difficulty - Suicidal, Waves - 7.
• ZEDs head size scale - x2.7, Players head size scale - x2.
• No head dismemberment allowed. ZEDs cannot be killed by taking off their head health and only die when they ran out of body health.
• It should be noted that ZEDs still take extra damage to body health upon draining their head HP (see step 9 of Damage To Take mechanics). The other side affects might occur, such as upon taking sufficient damage to the head Quarter Pounds and Fleshpounds become unable to enrage due to having a negative head HP value.
• ZEDs spawn much faster (x2.5 spawn rate multiplier).
• Each wave contains only 70% of the base wave AI amount.
• All ammo has 50% discount.
• Matriarch has a 100% chance to be replaced by Hans.

ZEDs have their health and headhealth adjusted by following multipliers:

All Fleshpounds, all the time. Almost.

Gameplay specifics:

• Boss replacement: Fight against King Fleshpound. King Fleshpound is capable of performing special "Whirlwind", "Ground Pound Explosion" and "Chest Beam" attacks. When King Fleshpound changes its battle phase it spawns a set of mini Fleshpounds (Quarter Pounds). Quarter Pounds also have a chance to replace common ZEDs.
• Difficulty - Suicidal, Waves - 7.
• Each time King Fleshpound changes its battle phase (including phase 0, when it appears on the map) it spawns a set of Quarter Pounds, which are the smaller versions of the normal Fleshpound. Quarter Pounds have less health and are slightly more vulnerable against various damage types than normal Fleshpounds. The amount Quarter Pounds spawned depends on the number of players on the server (1-6).
• ZED to be replaced by Quarter Pound - Odds: AlphaClot - 5%, Slasher - 10%, GoreFast - 10%, Crawler - 5%, Stalker - 5%, Bloat - 65%.
• Scrake has 90% chance to be replaced by Fleshpound (normal variant).
• Each wave contains only 55% of the base wave AI amount.
• King Fleshpound always spawns enraged.

Try to make ninety-nine Zed balloons.

Gameplay specifics:

• ZEDs regenerate HP: ZEDs enlarge upon taking damage and at the same time constantly regenerate their health / deflate. Killed ZEDs have custom gravity scale and also explode shortly, acting like balloons.
• Note: In this mode ZEDs do not die to headshots: regardless of where the shot lands ZED takes health and headhealth damage at the SAME TIME. Damage dealt to headhealth is a % of how much damage ZED took compare to its maximum body health. For example: Slasher (200 health, 50 headhealth) vs. off-perk SCAR-H (55 points of damage):

1. Slasher gets hit in body once, its health become 145 and its headhealth at the same time become (145 / 200) x 50 = 36.
2. Slasher gets hit in head once. Since the incoming damage is greater than Slasher's headhealth, the Extra Damage On Decapitation mechanic kicks in (see "ZEDs - Damage to take"). Slasher takes Rounddown (55x1.1) + (Rounddown (55x1.1) + 200 x 0.25) x1.1 = 189 points of damage to its health and is left with (11 / 200) x 50 = 4 points of headhealth.

• Maximum ZED size scale - x3 (achieved on death), size change interval - x0.1.
• Custom gravity factor for inflated killed ZEDs = -0.57 (for comparison, the default gravity factor is "1").
• Explosions are purely visual and do not damage players.
• Inflation explosion timer - 1.7 seconds.
• Each wave contains only 70% of the base wave AI amount.

ZEDs have their health and head health adjusted by following multipliers:
ZED:	Health scale:	Head health scale:	Regeneration

Gameplay specifics:

• ZEDs get stronger: Each time ZED deals damage to aplayer, is rally boosted, is within the AOE of Siren's scream attack or takes poison damage left by killed Elite Crawlers, it's health and size are increased by the listed value.
• Difficulty - Suicidal, Waves - 7.
• Stats increment happens for every ZED individually.
• Health increment affects both - ZED's max health and ZED's current health. Maximum health increased according to the listed %, if by the moment of health growth the ZED is missing some HP, its current HP value will be increased by (DEFAULT HP x % INCREMENT) amount of the points, but will never be more than its new max health value. In other words ZED will be healed by the given %.
• Unlike body, ZED's head does not scale up. Its HP and size remain the same.
• Each wave contains only 75% of the base wave AI amount.

Keep the kill streak going or die...

Gameplay specifics:

• Health drain: A health drain debuff constantly harms all players during the waves, unless there are less than 5 ZEDs alive. Killing enemies or making assists regenerates a portion of the player’s health. Other healing methods are deactivated. Killing Scrakes and Fleshpounds grants "Hellish Rage" PowerUp (without the health cost upon activation).
• Difficulty - Suicidal, Waves - 7.
• Players constantly lose health: 6 hp every 2 seconds. Delay to apply damage - 10s after wave begin. Damage type to take is "falling". Perk's damage resistance mitigates portion of this damage. Damage goes to actual health and is not stopped by armor.
• Health does not drop during trader time. Players are completely healed at the start of trader time. Health does not drop during the boss wave.
• ZEDs spawn much faster: spawn rate multiplier = x6.
