KF2 Specimen Files: Stalker Cloak, Counters and Statistics

The Stalker is a fast, mostly invisible ZED that gives anyone but a Commando a hard time. This page paraphrases the community "Specimen Files 2.0" entry from late 2015.

The Stalker.

When it appears

From wave 2 and in the boss wave. It likes to spawn wherever it can catch you off guard, often manholes, vents and windows.

Behavior

The Stalker approaches the nearest player while cloaked, uncloaks to attack and cloaks again afterward. A non-fatal headshot stops it from cloaking. On higher difficulties it uses acrobatic dodges. It sprints automatically when five ZEDs are left. Sprint chances apply only within 6-12 meters of the player:

Difficulty	Random sprint	Sprint when damaged
Normal	0	0
Hard	0	0.05
Suicidal	0.3	0.5
Hell on Earth	0.75	1

It fights ZEDs that attack it but dies fast due to low health.

Strategy

• Listen for wind-like echoes and watch for abnormal outlines; the cloak occasionally flickers and gives its position away.
• Any non-lethal damage temporarily decloaks it.
• Commandos see cloaked Stalkers and should focus them. With the Callout skill, the entire team can see what the Commando sees.
• Shooting a Stalker in the head to disable its cloak saves ammo and reveals it to teammates.
