There are two types of NX: Standard NX and NX Prepaid . Both types are used to let players purchase items in the Black Market. Although both NX types are similar, they don't function the same. NX can not be used to gift, while the NX Prepaid can. Also, NX is purchasable from Paypal and from mobile, while NX Prepaid are from game cards (i.e Karma Koin, Nexon Game Card, Ultimate Game Card).
Grade is a type of ranking that determines how much NX is used in a player's account (etc use around 100,000 to 499,000 NX to get Silver Grade).
NX can be obtained in a variety of ways such as:
- By completing surveys on the Combat Arms website
- By buying game cards, such as Karma Koin and Nexon Game Card
- Purchasing NX via mobile (available to the U.S only) on the Combat Arms website
- Using Paypal and/or credit cards to buy NX on the Combat Arms website
A lot of players complain that NX items are too overpowered, and puts GP only-users at an extreme disadvantage. The game was supposed to be "free to play", yet most of the GP gear aren't as beneficial as NX items. GP users would complain that people who use NX are being more advantaged than them.

The original F2P pledge was the statement Nexon adhered to when Combat Arms was first released. At the time, the pledge was maintained by the variety of GP weapons at the time and cosmetic variants in the Black Market.
Unfortunately, the company soon went back on all of their earlier promises. They began releasing unbalanced NX items and weapons with no GP variations (such as weapons and supply crates). No reason has been to given why it happened, though it is assumed that the change was made due to lack of sales. Click here for more information about the Free-To-Play pledge.
On a side note, the introduction of the TAU Weapon Upgrade system could possibly end some of the controversy surrounding NX and associated topics.
NX prices differ from regions/country.
