Editing Specimens

'''Specimens''' are the main antagonists of ''[[Killing Floor]]''. While they are widely referred to as zombies they are in fact failed experimental clones created by Horzine Biotech, a biotechnology company in London, England (It is not necessarily wrong to label them as zombies, however, as they behave in such a fashion). There are ten different specimens, each with different abilities and appearances. Along the game session, squad will face specimen in waves with trader time in between until they reach the final wave to confront the [[Patriarch]]. Wave count in a session is determined by [[Glossary#game length|game length]].

During wave time specimens spawn randomly at pre-determined locations near to the players, providing there is something obscuring the view between all players and the chosen spawn area. Specimen can spawn at areas in the map limitations or pour in from out of reach barricaded areas. Rates for multiple groups and delay between specimen groups to spawn in the map can get tighter, depending on squad's killing rate in the last few seconds. When squad manages to kill so many specimen in quick succession, more than one group may spawn at once with long distances between them and the specimen groups that spawn have shorter delays between them to spawn. There's a high chance that higher threats will start to flank you from rear positions in case players dare to use cheesy techniques to overwhelm specimen. Unless modified by mutators, maximum amount of specimen to be present in the map is 32 at once.

Specimens' attributes determined by what called as [[difficulty]] multipliers and each are separate values for health, damage and movement speed that affect by player count or difficulty level, sometimes both. Health of specimen tied to difficulty for low grade specimen, in the case of medium and high threats alive player count comes into play too. Specimen damage value scales with difficulty and has a small random spread for melee attacks and some special attacks. Movement speed of specimen again scales with difficulty and may vary with random spread at their initial spawn and their special attacks.

For cutting down time in a wave and keeping players alerted, specimen gain an immense hidden speed when any player or spectator don't have sightline on them. Hidden speed is well above four to five times of standard specimen movement speed. This bonus only scales up with player count in the game and applies to all difficulties regardless of alive player count. Out of view speed ceases and applies back regarding of player and spectators observing specimen. This allows flanking groups to cut the chase of kiting player or players easily if one is careless about spawn rates.

Specimen can replenish some of their health from killing players when themselves are injured and are below 90% health, roughly healing 10% of current value for each kill until they hit back over 90% again else, wipe the squad finally. Specimen that kill players with ranged attacks or have more than 90% health when they scored a melee kill, will not heal back from the kill. Low threat specimens also have cannibalistic tendencies and will feast on the corpses of recently deceased players or keep whittling at the dead body. During this time, other players can earn the "[[Achievements#Dignity_for_the_Dead|Dignity for the Dead]]" achievement. There is also a wide range of other achievements related to nonspecific Specimen kills. For a full list see [[Achievements]].

== Health ==
The base statistics for a specimen are its statistics on Normal difficulty. The difficulty multipliers for health are x0.5 for beginner, x1.0 for normal, x1.35 for hard, x1.55 for suicidal and x1.75 for hell on earth. The bottom line of table; "Increase per player", refers to the amount of health added per additional player, before difficulty multipliers are applied. For example, to find an enemy's 6 player health, add 5 times the increase per player value shown on the table to their Normal difficulty base solo health then multiply the result with the intended difficulty's health multiplier; or multiply the health difficulty multiplier times the additional players and add that to the base specimen health shown on the table according the difficulty. Alternatively, just visit the specimen's individual page for more information.

Trash specimen keep their head and body health when new players join, medium and higher grade specimen only gain body health and high grade threats gain both body and head health per player alive. Specimen that are able to do so, only scale up maximum health based on the alive players. New middle of the wave joiners or any sort of dead players will not contribute to the health pool of specimen. When a player dies, remaining specimen will not have their health scaled down but new batch of 32 specimen will spawn with their health scaled down to reflect the alive player count. Trash specimen only get affected by current health multiplier of the difficulty, and their maximum total health remains constant along the match just like their head health.

=== Total health ===
Maximum total health of specimen scales up by current [[difficulty]]'s health multiplier and for some specimen total health scales with current alive player count and specimen health multiplier of current difficulty. Only medium to high grade specimen scales up their total health with every alive player and difficulty multiplier. For ranged threats such as [[Siren]] and [[Husk]] this number is 10% gain per alive player, meat shield specimen such as [[Gorefast]] get 15%, [[Bloat]] and hulking specimen like [[Fleshpound]] get 25%, [[Scrake]] gets 50% and finally [[Patriarch]] gets 75% increase per alive player.

=== Head health ===
Maximum head health of specimen scales up by current [[difficulty]]'s health multiplier for base solo play health and head health of specimen increases per alive player depending on their threat grade. Only high grade specimen scales up their head health with every alive player; for ranged threats this number is 10% gain per alive player and big specimen gets 30% increase per alive player. Weak specimen won't have their head health scale with alive players. Only specimen to not have a separate head health pool is [[Patriarch]] which is the boss specimen and head health is always lower than total health. 

Landing a [[Glossary#headshot|headshot]] on a specimen will calculate the damage after adding headshot multiplier with the exception of [[Buzzsaw]], [[M99]] and [[Crossbow]] which adds headshot multiplier on themselves to check for target resistance later. After specimen confirmed to get head damage, multipliers will be added and resulting damage will retracted from its head health and body health together. While separated head health pool is part of the total health and always smaller than the total health of specimen.

When a specimen's head health is exhausted, it will be [[Glossary#decapitation|decapitated]]. Upon decapitation specimen will incur extra decapitation damage to their body health depending on the power of weapon that last hit them. If last hit damage they incur is strong enough to wipe them out, they will die on the point of decapitation. Decap damage bonus is expressed as [(Last Damage Amount + (0.25 * Max Health of Specimen)) * (Resistance and Damage Multipliers)]; quarter of specimen maximum health added to the last damage they incur and this value multiplied by any headshot, incendiary direct and resistance or vulnerability multipliers depending on hit location of the specimen.

As head health is lower than the specimen's body health just whittling away its head health down to 0 with a weak weapon, will cause it to bleed away on decapitation. After a soft decapitation occurs that doesn't kill them, specimen will get the value ''Braindead'', applied physics for ragdoll and slowly bleed out in a few seconds until they finally drop. Softly decapitating them with weak weapons will leave their bodies capable only of simple attacks, get headshot damage on body and wobble while walking slower for three to seven seconds aimlessly before they die. The ranged ones and other bulky specimen can stand headless for 5 seconds, [[Fleshpound]] is the only capable specimen to have bleed duration of 7 second upon a soft decapitation. Rest of the specimen only stays barely alive for 3 seconds when left to bleed out.

Head position on dedicated servers are not rendered server side on certain animations, so server has to use an approximation when trying to locate the head position on any pawn/target. When jumping, crouching or swimming animations, server places the head at the middle center of the said animations.

* Patriarch doesn't have a separate health pool for its head and can't be dismembered or decapitated unless dead.

== Attack damage ==
=== Melee attacks ===
Specimen gain damage bonus or lose efficiency compared to its base value, regarding the specific [[Difficulty|difficulty]] multiplier for specimen damage. This is 30% at Beginner, 100% at Normal, 125% at Hard, 150% at Suicidal and finally 175% at Hell on Earth. All specimen have a 5% spread at random on their melee attacks, causing attack damage to lose or gain 5% on hit at random. For very low damage melee attacks, this difference is nearly indistinguishable but still causes 1-2 damage difference per damage tick. For some big specimen with high damage however, that randomization can be the decisive factor if a player lives or dies in a bad scenario.

When specimen is lower than 90% of maximum health, melee attack kills performed by specimen upon the player will heal specimen for its current 10% of health. This healing mechanism has no exception and will heal any specimen that is low enough immediately as long as the last hit upon player is a melee attack. Specimen that use ranged attacks to kill players or over 90% maximum health, will not benefit from this healing mechanism in any way.

== Movement ==
The movement speed of specimens varies based on the difficulty, whether they are on land or in water, and if they have the ability to charge. Specimens cannot charge whilst in water. The difficulty modifiers for specimens' speed is 95% for beginner, 115% for hard, 122% for suicidal and 130% for Hell on Earth. All specimen has a very mild 10% spread randomization on their initial spawn. This might cause individual specimen to block shots for each other or stall behind at random, never giving an expected result at high difficulties against same encounters where this spread is very noticeable.

All jump heights are unique to the player and non-player characters in particular; there are no modifiers on the height specimens can jump. All specimen jump with 320-350 units velocity and their jump height will not vary or differ from each other by spread.

Notes:
* All movement values have up to 10% random spread for higher or lower speed on specimen's initial spawn.
* Crawler's horizontal pounce distance is 250 units at once maximum.
* All specimen get 20% movement slow down and worse reaction times from getting burnt.
* Fleshpound will only ignore the effects of slowdown from being crisped while enraged.
* Patriarch is the only specimen to be completely immune to slowdown from burnt state.

===Out of sightline speed===
All specimen has a hidden speed when out of sightline to seek players faster when no spectators or other players observing them. This hidden is speed is unaffected by difficulty and scales up only by the players in the game regardless of their dead or alive state.

== Bounty ==
Upon killing a specimen, the player is rewarded with a cash bounty. This bounty varies between specimens and difficulties. The base value is the bounty on Normal; for Beginner, this is doubled; for hard and suicidal/hell on earth, the floor values of 85% and 65% (respectively) are used. All values are in British pounds. While playing a short game (4+1 waves), all rewards are increased by 75%.

== Wave layout ==
In a standard game, specimens first appear during certain waves, the timing varying according to the length of the game. The first, last, and final waves always contain the same specimens; in these waves the only thing that changes is the numbers of specimens, which is based on the game length and the number of players.
