With the Platinium transporter you have the possibility to transfer the game currency Platinium from you to an alliance member. For example, if an Alliance member needs 100 Platinium and you have 500 Platinium in your game account, you can build a Platinium transporter in the tank factory of your base station. There you have to enter the height of the Platinium before building, which will then be transferred from your game account to the Platinium transporter. The minimum height is 1 platinium.
In this example, there are 100 Platinium in the transporter and 400 remain in your account. As soon as the Platinium transporter enters your alliance member's base, the transporter disappears and your alliance member is credited with the Platinium.
Important: Immediately after the completed Platinium Transporter leaves your base, it will flash as a red dot on the minimap and will be visible to every player (including your opponents). If an opponent manages to destroy your Platinium transporter, the Platinium in it will be credited to his account. For this reason it makes sense to always send along convoys.
