The Scout perk in Call of Duty: Black Ops for the PS3, Xbox 360, Wii, and PC is pretty much a sniper’s best friend. It allows you to hold breath longer when scoped, so you can take those few extra seconds to line up your shots just right.
The Scout Pro perk upgrade gives you the added benefit to switch weapons faster.
Don’t forget that you need to purchase the Scout Pro perk upgrade after it’s unlocked for 3,000 COD points.
Here is the list of the Scout Pro perk challenges, and a few tips to help you complete them:
Headshots — Get 30 Headshot kills
If you’re the sniper type that wants this perk, then you’re already doing this and I don’t need to tell you how to do it any better than you already do.
One Shot Kills — Get 50 One Shot, One Kill Medals
This one will probably take you the longest of the three. You have to kill your enemy with a single shot. This can be done at the same time as the Headshots challenge, assuming you landed a headshot kill on the first shot.
Secondary Kills — Get 50 kills with secondary weapons
You just need to get 50 kills with any secondary weapon. This shouldn’t take you that much time if you focus on it specifically. Best done on close quarters maps since most of your secondary weapons are short range pistols.
