So it has been made official there are going to be no Pro versions of any of the perks in Black Ops 2. Hard to believe right? I was pretty shocked. However, this came directly from the mouth of David Vonderhaar so I am thinking there is no disputing it:
"What Treyarch didn't want to do in its new system is offer the player perks or upgrades that change the way default settings function. All perks from previous games that modify the way weapons perform and the ability to unlock "Pro Perk" rewards have been abandoned in Black Ops 2 under this new philosophy..."
So here are the perks that will be in Black Ops 2, and this is going to be it, no additional abilities will be available in a "Pro" version of any of these perks:
Flak Jacket : Take less explosive damage.
Ghost : Cannot be detected by enemy UAVs while moving.
Blind Eye : Unaffected by AI-controlled perks.
Hardline : Receive bonus score points.
Lightweight : Move faster, take no damage from falling.
Hard-wired : Immune to counter-UAV and enemy EMPs.
Scavenger : Replenish ammo and grenades from fallen enemies.
Cold-blooded : Resistance to targeting systems including Dual Band, Target Finder, Sensor Grenades and player-controlled aircraft.
Toughness : Flinch less when shot.
Fast Hands : Swap grenades faster, use grenades and equipment faster, and safely throw back frag grenades.
Engineer : Show enemy equipment in the world, delay explosives and re-roll and booby trap care packages.
Dead Silence : Move silently.
Extreme Conditioning : Sprint for a longer duration.
Tactical Mask : Reduce the effect of flash, concussion and shock charges.
Awareness : Enemy movements are easier to hear.
Dexterity : Climb ladders and mantle over objects faster, recover from melee faster and aim faster after sprinting.
