Stalker

Summary
A very tall, gray and disturbing creature that has special powers. It grabs survivors when they get close and takes them away from the main group to be killed. It turns invisible when idle, can shield itself and move very quickly. It's a survivor's worst nightmare.

Background Story
The whispers from the fog haunt the dreams of those who were there at the beginning. They cause them to recall missing comrades. Silhouettes, tall, thin, sprinting through the corner of their eye. They turn, and nothing is there.

Every night, the whispers kept them awake. They set rules. Who would be watching, where they would be watching. But every morning, more and more of their comrades would be gone.

There was nothing they could do.

It's been reported that the creature's most commonly found in an area called Last Harvest.

Perhaps most significant is the fact that humanoid, mini version of stalker-like person, with a set of blue headphones, black fur jacket set and a black scarf appearance, has been spotted walking through the fog.

Some believe this may be the sign of some being able to resist the SANI Virus.

Survivors

 * The Stalker is very fast, track the movements so you can kill it more easily.
 * Communicate with others. If a Stalker is nearby, warn fellow survivors to avoid preventable accidents.
 * Playing in third person greatly lowers your risk of surprise ambushes and being caught by the Stalker.
 * Since it's tall and very easy to see, it should be easy to kill.
 * Be on high alert if you hear whispering.
 * If by any chance a Stalker is near you, you should punch or have a secondary that stuns.
 * Freezing or stunning it will immediately drop its victim.
 * An Icestaff or Icegun can assist you due to its long freeze time.
 * If a Stalker throws you off the map, you respawn and do not die in void.
 * This doesn't apply to Terminal Decay, Mogadishu Transit or Victoria Harbor as they're dead boundaries in-place on those maps.
 * You will also be respawned if a Stalker throws you into unswimmable water.
 * Occasionally, being dropped into Caved In water could kill you.

Zombies

 * Assist Stalkers by distracting other survivors, allowing him to grab a survivor with ease.
 * Jump from high points of a map with a survivor and let them go to kill them with fall damage.
 * Don't jump off the map with kidnapped survivors as it will respawn them.
 * If a survivor dies while being in your arms, you will also die.
 * This means buying one will always come out as negative money even if you kill someone.
 * Standing still will allow you to become invisible.
 * Very useful for the last phase of Arena.
 * If you are caught in a Pipebomb, you will lose invisibility.
 * If you capture a survivor, bring it to a Brute or a horde of Infected, as this should easily finish them.
 * If none of these are available, bring them to a Leaper or Edgar instead, as they will trap the survivor.
 * If there only a few to no zombies around you, try to put them close to a zombie spawn.
 * If a survivor is on lethal heights, you should consider throwing the survivor off the building to make them lose some health.
 * Not including No Mercy.
 * Separate survivors from a group in order to stop the group from killing you.
 * Since you can't kill players by dropping them near the edge or in water that kills, try using other environments such as a radiation pool, boundaries such as the rocks in 1930's Kingstreet and Victoria Harbor or the water at Panama Beach.
 * Use glass shards if available in order to do some damage to them.
 * Use the forcefield at spawn to prevent you from getting spawn killed.
 * Throwing survivors off the map in Rescue can delay them from getting to the Helicopter, making it worth doing so, most notably on Victoria Harbour.
 * Maps like No Mercy are great. Your dark figure, invisibility, and glass to force survivors into makes this map one of your golden opportunities.
