The Mystery Trade station is located in Mesoterra.

Jammers can leave an item at the Mystery Trade station to later receive an item another Jammer has left behind. Remember that any item you send to Mystery Trade cannot be returned, so be sure about the items you select to trade! 

Once trading, come back later to see if your items have been traded. When your items have been traded and are ready to collect, there will be a red exclamation mark outside the station.

Remember your items are being traded for mystery item that another Jammer has left behind at the station - this is not a trade with AJHQ.
