Thats right enemyace. You can have as many skins as you want, like Eskimo's Peace C47 and Richard Simmoms Lgay7, but only the skins approved by HTC, and d/l by the game will be able to be chosen from the hanger for use in the arena. Offline there is no limit to the amount or type of skins you can use, they just wont be one of the maximum of 15 skin options you can pick while online.
