what should?
What Shouls i do with 80 coupons?
1.Get Ak-Knife
2Get Deagle Gold
3.W8 For The Next patch
dont get ak knife thats for sure, and i wouldn't care about a pistol save for a gold gun.
If you are a rifler, get some rifle, but don't get the deagle-g, it's pretty much useless when you already have an automatic gun.
If you snipe, definitely get a deagle (The gold is more about looks, and the camo is more usable) .
TBH the ak knife isn't a bad gun, but I wouldn't get it based on personal preference.
