I’ve been using headphones while I play Halo for a couple of years now. I hear things I never heard on my TV speakers. One thing I heard in Reach a lot was a person’s footsteps while they were running. With Halo 4, I don’t hear the other team’s footsteps at all. I get surprised a lot more with assassinations because I don’t hear them. I mostly play SWAT so there are no Wetwork stealth specializations involved. I hear my teammate’s footsteps all the time, just not the other team. Is this a bug or was this by design?

I use 7.1 surround headphones, and i hear the other teams footsteps… not sure why you can’t.

I can hear them fine, too. Are your bass settings too low?

Footsteps are louder than in any other Halo game, but there’s also more background noise, so I can understand you focusing on other sounds and not noticing the footsteps.
It’s not a bug, it’s you.

I hear my team’s footsteps all the time so I don’t think it’s my bass. I turn around when I hear any footsteps and it’s always a teammate. I just don’t hear the other team’s at all.
