yes it is possible to quick scope. so here are the steps:
Step 1: have someone be a dummy and have them stand in front of you.
Step 2: look into you scope and aim at them. Also hold you breath while doing it.
Step 3: look out of your scope and look back in and shoot the dummy really fast.
S thee you have it, that is how you quick scope.
You can not quick scope in Black Ops as quick as you could in Modern Warfare 2, but it is still possible. Try no-scoping. In my opinion, it's more enjoyable.
Quick scope
yes
Practice.
By using seight of hand pro to scope faster.
yes
I play Modern Warfare on Xbox 360. I quick scope on sensitivity level 8. It may be different for you.
yes! Its back just like it was in MW2.
Intervention.
Yes
No, as the very meaning of scope is "a part of the program"
It all depends on how you play. If you hard scope, it is probably the Barrett 50 cal, however if you quick scope and drag scope it is the Intervention. if u do both its the WA2000 but its kinda nooby...
