A kill in FPS games like Modern Warfare 2, where the person using a sniper rifle (like the Intervention, M40A3, or R700) zooms in with the regular scope barely enough for the cross-hairs inside the scope to become visible or just before resulting in a Dark Scope and then firing the weapon resulting in a kill. Thus the Quick-Scope.
Perfect MW2 Class for this: Intervention+FMJ, Sleight of Hand Pro, Stopping Power Pro, Ninja Pro (cause noobs need steady aim).
OMG! Did you see that!?!?! I just 360 quick-scoped OpTic DTreats across the map on Overgrown!
Another way of call it the "Sniper Rifle". Most often used on hardcore Call of Duty kids when they play any FPS game that is Call of Duty or not.......
The 360 Quick Scope is a difficult technique but often used in FPS games (Call of Duty Mainly). Is that a player with a sniper rifle, taking into account their aim sensivility is on "Insane", move the right stick to the right or left and the player starts to move the aim quickly and remain in a situation which can go dizzy until you have a lucky shot and kill an enemy. In fact, it takes more than 360 degrees to kill someone, because it is very difficult to know exactly where you're going to shoot and takes a little longer to get ready. The 360 Quick Scope is used frequently to presume the players and basically, people do this is a Final Killcam.
*FINAL KILLCAM*
*A Player do a 360 Quick Scope and kills the enemy player*
Enemy player: "That guy is insane! He used a 360 Quick Scope to kill me, that sucks..."
