Yeah it may be a bit of a nitpick, but I haven't really been digging the effect in its current state as it's been shown in some of the videos we've seen. It looks too much like horizontally-lined video interference than how it looks in the films. But it's still early days yet, so hopefully that's something that looks better on release.
I'm hoping they basically just do it like the Wraith in Dead by Daylight, who's basically that game's stand-in for the Predator. His cloak in that game looks extremely Predator-like.
