I had my druthers, I would’ve made them basically organic terminators, with elements of the raptors in JP: Nigh-unstoppable, relentless, and cold blooded. What was campy slow walking in the original due to the special effects budget would be a methodic and deliberate plodding, again, similar to how a terminator moves. ( Which ties into the idea they like to exhaust their prey). Very literal or even logical in their thought processes. That’s why they immediately assume the colonists were invaders.
