Also known as the Weapons Auction.
It is restricted to certain events, and therefore not a permanent feature.
There are two rows which separate the highly rare (in demand, event-exclusive or both) weapons and the more common weapons (craftable, obtainable from decoders or both). A player has two choices, which are either to bid on a weapon or pay for a buyout.
By placing a bid on the weapon, the player commits pays the current bid price, along with a 20 mileage increment. For example, if the current bid is at 3,300 mileage, the player has to pay 3,420 mileage to outbid the previous bidder.
The timer increases whenever a bid is placed. Should someone outbid one's current offer, he or she is offered the option to pay additional mileage or give up and wait until the auction ends and collect back the mileage.
An alternate measure is to pay for a buyout. When this happens, the auction ends immediately and the weapon goes straight to the purchaser at the expense of a higher cost.
A cooldown of 10 seconds is imposed whenever the current listings are cycled.
Likewise, players have the choice of listing their starting bid, and the buyout price. Only permanent weapons are sellable, and once the weapon has been listed, a 20-minutes countdown begins. The limitation is one item per listing until it's sold.
If the weapon fails to sell, the player re-collects it and could re-list it, marked with a red tag. Once it's sold, he or she could then collect the mileage paid by the buyer. A blue tag would appear.
