Multiplayer Perks
Perks are passive enhancements, and you get one slot in your Profile Sets for them. These perks are always in effect and there are currently two perks available through leveling.
Enhanced Autobash

Awarded when the player reaches level 20. This ability increases the number of characters you can run into while in high profile without stumbling. This is useful when you're in chase or pursuit mode and any slow down could result in failure. You can always just use the unarmed hand button to shove people as you're running, but this perk will help you out if you can't get to it in time.
Blender

Awarded when the player reaches level 19. The Blender perk changes one character in a group to your character skin when you blend in with them, unless one of them already has the same skin as you. This is a good way to quickly fool a pursuer you know is close to you without wasting one of your abilities to disguise yourself or morph the whole group.
Fast Getaway
Awarded when the player reaches level 33. The Fast Getaway perk reduces the amount of time a player needs to break the line of site or hide in order to escape from a persuer. This perk is useful when your persuer isnt far behind you and you need to getaway fast.
Resistance
Awarded when the player reaches level 27. The Resistance perk reduces the amount of time one is stuned by his/ her targets. This perk is useful when stuned and your target tries to escape, using this typically gives them little time to escape and keeps you closer to your target. Also it reduces the amount of time you're left helpless on the ground for pursuer to easily kill you.
Wall Climber
Awarded when the player reaches level 22. The Wall Climber perk allows you to climb up walls easier. This perk is useful in chases when you need to getaway quickly or when you need to catch someone while climbing up a wall.
