MapleStory 2 Mesos will serve as the game’s main currency. You may purchase equipment (weapons and armor), Potions, equipment, transport, cosmetics, guilds, real estate, and perhaps to improve your character’s potency. These items are sold by NPCs and by other real-world players, but some items can only be purchased from other players.
Another form of currency in this game is NX. NX is obtained by exchanging real money for a gift code, which can be redeemed for NX. These redemption codes are often found in a gift-card like form, and can purchased at places like 7-11, Target, Walmart, etc. NX is used to purchase special items in the Cash Shop (another shop in the game, but only uses NX as currency, therefore mesos cannot be used here). Some of these items include Double Experience coupons, mounts, unique character effects and faces, etc.
