I've often wondered how the Perks in the Call of Duty series would work as edges or talents of various games, some bring something new, others are already in, and still others have little to no bearing. So here are some.
Modern Warfare Series
Assassin: Combine UAV Jammer and Cold Blooded
Bomb Squad/SitRep: As Danger Sense
Bandolier/Blast Shield/Bling/C4x2/Claymore x2/Frag x3/Overkill/Special Grenade x3/UAV Jammer: Gear based, not really an edge.
Blind Eye: Can make Stealth roll to hide from enemy Unmanned assets and vehicles.
Cold Blooded: Able to make Stealth roll to avoid thermal/FLIR imaging.
