Eine liste gefunden, nicht confirmed und cih zweifle noch ein wenig an der Sache, möchte sie euch aber nicht vorenthalten
» Blind Eye - Or, you can call it the “anti-killstreak perk”, because this perk makes you invulnerable to killstreaks from other players. That means you won’t get attacked by their choppers, etc. You will, however, still show up on UAV and the like. If you upgrade it to the pro version you’re not only protected from killstreaks, but you get the ability to help take them down more quickly. Your rockets will lock on faster and your gunshots will do extra damage to vehicles. You’ll become an anti-killstreak machine.
» Assassin – This fills in the other half for Blind Eye. Where Blind Eye protects you from things like choppers and chopper gunners, Assassin makes you invisible to things like UAV. In addition, you won’t show up on thermal sensors or heartbeat sensors. You’re an assassin, invisible to all but the naked eye. The pro version, as you’d expect, takes this even further. Upgrade to it and you’ll become invulnerable to CUAV and EMP and, perhaps even more importantly, when enemies see you your name will not show up and your enemy’s crosshairs will not turn red, leaving you free to sneak around in plain site..
» Point Guard – Frustrated that you’re always racking up tons of assists but are never quite able to finish your opponent off and get your hands on those cool killstreaks? The aptly named “Point Guard” is here to help. With Point Guard, you’ll get credit for a kill towards your killstreak bonuses every time you get two assists. It won’t show up on the scoreboard as a kill, but it will count towards your acquisition of killstreaks. So if you get 6 assists without dying, you get a UAV. Or if you get 2 assists and 2 kills you’ll get the same.
» Dead Silence – While Assassin makes you invisible visually, you still make noise. Enter “Dead Silence”, which takes care of that. You make no noise, not your footprints, reloading, etc. While Assassin makes you unseen, Dead Silence makes you unheard.
» Recon - Details are still hush on this one, but it appears it will give you a more advanced radar than you have naturally. Perhaps it will work to counter perks like Assassin that would typically make an enemy invisible to radar.
