There have been two pretty important features missing after the unreal upgrade/port.
The iconic glowing eyes that would light up while in infrared regardless of being clocked or uncloaked have been removed.
The predator cloak stays completely invisible all the time when standing still regardless if your crouched or not, and goes into complete invisibility way faster. It used to go completely invisible only when you were crouched before the upgrade, and while standing you were still somewhat visible and would not completely blend in with your surroundings.
Can we please see these two iconic features returned back into the game with the same blending rate as before the upgrade.
It would also be more accurate with the first few movies the game is based off with, like it was before.
