Where are the goddamn footsteps in this game?

I'm trying to give this game a fair shake. I really am. But it's so frustrating being shot from the back without ANY sign ANYONE was there at all. SOMETIMES if you are inside a building you can hear slight metal thunks but even then it's only sometimes.

I know I will get discredited right now for saying this but I come from Hunt and Arc. Collectively I have 900+ hours in those games. I'm spoiled with audio clarity and knowing where people are EXACTLY. It keeps things fair and interesting.

Marathon is very heavily lacking in this regard.
