That plus have it so that if the FT moves at any speed quicker than a walk they make a bit of noise. Jumping/sprinting they make a huge amount of noise. All which can be picked up via the Predator’s bio vision.
Solves a couple of issues at the same time, in my opinion.
The Predator does already have a general idea of where the FT is, at the start of the match anyhow. They are usually directly across the map from your spawn.
