“The Stalker will be largely cloaked and very hard to see, until she is close enough to gut you. Listen carefully for her.” —Loading screen tip
The Stalker is a weak but fast specimen with the ability to render itself invisible. It can barely be seen, and its muttering and breathing is the only sign that one is around. When it attacks, it leaves this camouflaged state, before trying to hide again. Players who have chosen the Commando perk are able to make them out, however. Stalkers will be revealed to them within a specific range, based on the Commando's perk level. Stalkers appear early on as the waves progress. Fortunately for the players, the Stalker has a low amount of health. Often, they’re killed by players accidentally when caught in the line of fire, explosions from grenades or Pipe bombs, or set ablaze from a Flamethrower.
The Stalker is one of only two types of specimens with female form, the other being the Siren. When visible, the Stalker's skin is pale and stained with blood. Her eyes are blueish-white and she only has hair on the right side of the head; the left side is bald with a large scar. Several other large scars can be found dotted around their torso. She wears several fabric bands and black frilly underwear, but no shirt or top covering.
For the Twisted Christmas update, she was re-skinned, and dubbed Mrs. Claws. This skin depicts a blond-haired female humanoid wearing a red miniskirt with white trim, a red shawl with a cloth barely covering her breasts, and red-and-white stockings saturated with blood. She also appears to be wearing gold-framed glasses and a gas mask with the visor broken.
For the Summer Sideshow update she was re-skinned into the Lovely Assistant. This skin depicts blond-haired female humanoid wearing a red, black and gold ensemble, a black and red magician's top hat, black and gold gloves, and red and gold boots with black laces and black fish-net stockings. She is also wearing a black thong and black leather straps on her legs. Her face is mutated, revealing beast-like teeth inside her mouth. This Stalker is slightly different with her invisibility appearance. Instead of being a barely noticeable shadow of the stalker themselves, the Lovely Assistant skin makes the character shimmer. This is much more noticeable than its standard appearance.
For the Halloween Sideshow her skin was based on the Summer Sideshow model, however the costume is black and has golden trims, and some portions of her corset reveal her skin. Her hat has also been changed into a witch's hat.
For the Hillbilly Horror update, she was re-skinned into a blonde "farmer's-girl" archetype, dubbed Maggie May, wearing a plaid red blouse and jean shorts.
Although the Stalker’s simple tactic is the element of surprise by using her camouflage, she moves directly towards the player without any fancy or specified paths. When she gets close enough, she takes position and attacks, either the player is unaware or is aware, her camouflage wears off for a brief moment. Her location is revealed to any observing players. Players are given a chance by pinpointing her either by spotting her shaded figure, or listen for mutterings or breathing. Stalkers are found in duos or trios, or in a large groups sometimes, to stalk and kill the player.
Created by Project Stalker in Horzine Research Bunker 6 deep in the Wyre forest, Players can find the remnants of the lab that led to the rise of this specimen; a semblance of Kevin Clamley's daughter, Rachel. Failed Stalker experiments lay on the table phasing in and out of camouflage. A glimpse of the lab's descent into madness can be found on the lab walls and floors: phrases such as "Hide and go Eat" and "You are the prettiest when I can't see you."
|Beginner||Normal||Hard||Suicidal||Hell on Earth|
A Stalker's base health total health is 100, and head health is 25. These figures are then multiplied by 0.5 on beginner, 1.35 on hard, and 1.75 for suicidal. The base bounty value is £15, this is then multiplied by 2 for beginner, 0.85 on hard, 0.65 on suicidal and hell on earth and reduced to its floor value.
The Stalker can usually be killed with a single shot from the majority of weapons but, due to the requirements of the Commando perk, it is advised that you or a teammate take them out with an assault rifle.
While the easiest way to detect cloaked Stalkers is to use the Commando perk, this isn't always an option. The first sign of the Stalker's existence is often her distinctive vocalizations, which can give you a general idea of the direction from which she is approaching. She generally is identified with the deep breathing, hissing voice response of "give us a kiss," or short laughters. Another warning of her presence is that when a stalker is close to a player, hard, fast breathing is heard, one can assume that this from the players themselves. These vocalizations, however, are often overwhelmed by the sounds of gunfire on multi-player. Under most circumstances, it is possible to discern them by the semi-transparent white sections of her limbs and face, or by her moving shadow. The Stalker is often found traveling with Crawlers because they share spawn points, but this tactic is a less reliable indicator.
