So, Cloak tracker took me a while to get and I assumed (due to its cost) that it would be very useful later on in the game. Imagine my shock! Finding out that there are a total of 5 cloaked enemies in the game and they all occur, at once, 5 minutes from the end credits.

Am I missing something? Or is cloak tracker the single most redundant and expensive suit upgrade in the entire single player campaign?

EDIT for name error

Yeah, it's useless.
One of them stalks you when you go through a burning building earlier in the campaign, but they only attack at the very end.
