Call of Duty: Ghosts will be accompanied by yet another redesign of the Perks system for multiplayer. A blog post from Infinity Ward explains how these custom abilities will work in the game.
Ghosts offers players 35 different Perks. Each Perk carries a point value of 1 to 5. Players have 8 points to spend on Perks. However, you can gain extra Perk points by taking equipment out of your Primary Weapon, Secondary Weapon, Lethal or Tactical slots. In other words, you can head into battle with just a rifle and 11 points' worth of Perks.
You can unlock Perks in two different ways. Each Perk will be automatically earned at a certain level. However, if you want a certain Perk early, you can spend some of your Squad Points (a currency earned through gameplay) to unlock it. I imagine most players will do some combination of the two.
The Perks are organized into seven different categories. Here's the full list of these categories as well as a couple example Perks within each:
Speed: Outrun and outmaneuver enemy players. Speed Perks are all about getting the lead and staying ahead.
Sleight of Hand: Faster reloading.
Stalker: Move faster while aiming.
Handling: Dexterity and control drives the Handling Perks, improving actions and accuracy.
On the Go: Reload while sprinting.
Steady Aim: Increased hip fire accuracy.
Stealth: Stealth Perks aid you in staying out of sight, maintaining a low profile and engaging on your terms.
Takedown: Kill enemies without revealing their death locations.
Incog: Resistant to targeting systems including: Recon, Thermal Scope, Tracker Sight and Motion Sensor. No name or red crosshairs when targeted.
Awareness: Keep in tune with your surroundings. Awareness Perks help you survey the environment and detect enemy players. Examples include:
SitRep: Detect enemy explosives and tactical equipment.
Wiretap: Utilize all active enemy and friendly SAT COMs on the field.
Resistance: A hardened endurance reduces the effects of fatigue. Resistance Perks keep you going through tough engagements.
Focus: Reduced weapon sway when aiming down sights and reduced flinch when hit.
Blast Shield: Increased resistance to explosive damage.
Equipment: Tacticians swear by their gear, and Equipment Perks ensure you have the best tools on hand.
Extra Tactical: Additional Tactical equipment.
Extra Attachment: Extra attachment for your weapons.
Elite: Elite Perks offer special abilities that affect your loadouts in a variety of ways.
Gambler: Spawn with a random Perk.
Ping: Activate a sonar ping upon killing an enemy, revealing nearby hostiles.
I'm not sure why the Perk system gets reshuffled every year. Perhaps it's to balance the power of some of the newer Perks that IW's adding this time around? Regardless, this new structure seems pretty easy to understand so COD vets should be able to jump into multiplayer with minimal fuss next week.
