So I think every character you get has at least 3 loading screens 1. The one you get when you first buy them(It will look similar to what you see now) 2. The one you get when you get their m3 skin 3. The one you get on their birthday(If you're online during that time) Buck and Alan both have special loading screens if you pick either as a starter(You'll also get the screen you'd get when buying them) Some may have more, but they are usually merchant exclusive. You can choose which loading screen you use if you click the settings button.
