Players start off with a free, cheap Mechanaught. Credits are used to purchase new parts, weapons, and skills, or secondary items such as repair points or paint and acquired through the various game modes. Some parts can only be purchased with real money via the NCcoin micropayment system. Most items in the game can be purchased using credits or NCcoins. Most items in the game can be bought for a time-limit or, for a higher price, a level of durability. If the time limit or the durability points of the item run out, then the item is lost and must be repurchased or the item must be repaired, respectively.
