+ fun to try to pull off shots and not getting hear ( time with explosion etc)
I didn't know you could do that.
Wouldn't be worth much though, because only the soldiers who're supposed to fight you will hear you anyway. E.g. when you shoot the first guy in the demo, the one leaning in that entrance, the guys just 30something meters from him won't notice. Until you creep down and shoot one of them. Then they're all on to you. But not the absent-minded dude one building farther who you're supposed to take out with the Welrod. Similar situation in the next street. You shoot around wildly, taking out everyone on the ground plus the sniper in the building, but the guy napping, listening to music is blissfully ignorant of all of this because you're supposed to "sneak up on him" when you climb up to the vantage point later on.
None of this makes sense at all so it seems weird to me that you could somehow mask your shots with environmental sounds when hearing is such a non-issue otherwise.
Not saying you're wrong, mind you! I honestly don't know. It would just seem odd to me, considering how the game seems to work. That's all.
Offtopic: I could never picture how that could be realistically possible anyway. How do you know when
exactly the explosion sound is going to happen? Maybe you see a huge red rocket fall, ok, for the sake of argument, but how accurately can you then judge how far away it's going to land? 300m makes a full second difference due to the sound's traveling time!
People are going to hear the explosion at different times too.
They're also going to hear your shot at different times. Assuming you're a super-robot who can triangulate all of that on the fly and can still time your shot perfectly: Who are you going to time it for? The guys 100m from you or the guys 400m from you? Again a full second difference.
Unless you time it perfectly, and even then unless the explosion is close and insanely loud, a shot sounds different than an explosion.
It just doesn't seem possible to use this as a viable tactic (as a freak accident, where you get insanely lucky and there is just one other group around who could hear the shots but miraculously they miss it because an explosion happened to happen at the exact same time) unless it's happening in a movie, where none of that matters.
Say, Enemy At The Gates...
With barrages of explosions maybe. Under fire from a Katyusha, perhaps. Food for thought.
