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, including the Patriarch, each with different abilities and appearances. Decapitating them will leave their bodies capable only of simple attacks and walking for a short period, with the exceptions of the Patriarch, Scrake, and Siren, who do not survive decapitation. 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 spawn.

Several of the Specimens have cannibalistic tendencies and will feast on the corpses of recently deceased players. During this time, other players can earn the "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 0.5 for beginner, 1 for normal, 1.35 for hard, 1.55 for suicidal and 1.75 for hell on earth. Increase refers to the amount of health added per additional player, before difficulty multipliers are applied.

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, 120% for suicidal and 130% for Hell on Earth. There are no modifiers on the height specimens can jump. For comparison, human players run at a speed of 200 units when in perfect health, and jump 325 units.

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.

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.

Removed Specimens

There are 5 unused/removed specimens from the game. They can be accessed via console or sandbox. 3 of which can be playable and none of them have their own original models. They are left in due to the coding from the KFMod.

Icon	Name	Description
	Shade	The Shade is a crawler that hops like mad. Causes serious amout of damage when several are around. Unlike the crawler, they do not crawl but already leap when they spawn.
	GoreFastSP	The Gorefast SP is Gorefast with more speed. No other major differences. Its reason for being made is unknown.
	Chain-Gunner	The Fleshpound Chaingunner is a Fleshpound that shoots from his left arm. It is very buggy and his "chaingun" arm moves around the place due to a lack of animation.
	Wretch	In-game, Wretch (As well as Infected Soldier) is an invisible enemy with the hurt SFX of Stalker/Siren. They would die from either 1 - 3 hits. They cast a shadow and will still be "standing" when killed.
	Infected Soldier	Same as the Wretch.
