I’ve regarded invisibility to be the overall best perk to stay alive in Call of Duty. I’ve been running with the Suppressor most of the time in Black Ops II. But lately I’ve trying out new weapons and level ‘em up respectively. Therefore, for a big part, I’ve been using other attachments than the Suppressor.
Being exposed on the enemy’s mini-map is not bad if you can turn the table. Be prepared; flip it to your advantage before the gunfight starts. Control the engagement. And if there’s an Orbital VSAT or UAV above, it should be really easy to be ready and able for the next noob to pop up.
Recall the tactical grenade called Decoy featured in the first Black Ops, but now use yourself as bait. Lure the enemy into a kill-zone, but don’t fuck up or you’ll be dead.
