Easy Supply Points and Exp.

[Nizzle]

Easy Supply Points:
Play Infection
Better to play 20 rounds but any amount of rounds is fine I believe
After the game, if you played the whole match, you should get 1000+ supply points
On someone ranked 1 - 8, 1000 + supply points should give you at lest 10% (Idk about higher ranks since i only tested this on my level 8 account)

Easy Exp.
Play Prison Break Rescue solo
After escaping the fire run up the stairs
Then open the door to the room with the controller you're suppose to activate
Go and Stay in the small square room before the spawning room
Sit and farm bots until time runs out.

I did this and got close to 1100 xp after time ran out.
Kills: I get around 1100 - 1200
Lucky Shots: 5 which is the max you get in a match
Gun: Bizon or PPSH
