It went pretty easy, the gun is easy to use
I used the AN94 with 4x (ACOG) scope ,magnum ammo and a 40mm shotgun.
The platinum star is awarded at 1000 kills and gives 10000 points.
This might seem easy to most people, but since I can't stick to one class long enough, this took me ages...
This is the screenshot after the match.
This screenshot was taken in game,
And this one shows that it stops counting!(although it still counts the total amount of kills with the weapon) making :'( a second platinum star with this weapon impossible!
