It increases even more visibility of cloaked enemies.

BTW, I use your topic to say that this perk is bugged: half of the time (if not more) I does... nothing. I mean nothing at all.

It's all about two things:
1)Distance you can see cloaked players on

2)How visible they are


For example,if a player has cloak enhance II,which means he casts no shadow while cloaked,and if you have cloak tracker II,you still can see his shadow,while others can't

Cloak Tracker - Creates particles on Cloaked enemy within 20m
UPGRADE II - Causes enemy Cloak to flicker after 7 seconds in radius
UPGRADE III - Causes enemy Cloak to flicker after 5 seconds in radius

After getting Tracker nearly to lvl3 yes it shows steps from cloacked players.
Prob is the tracks disappear quite fast. Other problem is that there are so many effin' static players staying cloacked all day that it just makes this module lose a lot of interest.

Only one thing nice of it is that there is some sort of slight buzzing sound that increases in volume. It means someone is close to you. Be weary though that it could be someone right above or below you. It's actually a little more useful than the primary function of the module itself imo...

As of the flickering delay, it is as in "once opponent cloacked is within affected area, the flickering starts in x seconds". This is why Markassin said that sometimes it doesn't do anything. It's because as you run by, the oh-so-many mr.standing still forever cloack guy started flickering when you went right past him, or that the cloacked dude was outside of the detection radius. As a side note because of my color blind issues even the cloack tracker keeps me often confused when it works. -_- Them Crytek be fancy with graphics and all but it sure don't help my retarded eyes ^^

From what you wrote you look like you have the motive of trying to be a cloack buster. What's exactly on your mind?
