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.

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.

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.
