Instead of being in the dark while waiting for hidden aliens to finish their turn, I think it would make sense for my soldiers to be able to figure a general direction toward the sound that they've heard. Maybe the footsteps are just for atmosphere, but surely if someone hears a gunshot they should be able to tell whether it came from north, south, east, or west. Do we hear every single alien movement on the map or are they tied to the proximity of soldiers? If the former, then I guess never mind. If the latter, than instead of staring at the static art when an alien pistol is discharged, I would like to see the map centered on my nearest soldier with an arrow showing the general direction towards the sound.
