Yea. Some characters you need to rack up kills for their costumes. You need to get kills with some characters after you choose a side to register on. And some characters only can get an alternate costume depending on the side you choose. But the dumb part is their is only one alternative costume for each character unlike the first one.How do you change the costume of your character in marvel ultimate alliance 2?

the other guys answer is for the first game. if you have unlocked the costume, then you can change costumes the way you said. (NOTE: YOU HAVE TO UNLOCK IT FIRST! MY FRIEND DIDN'T KNOW THIS AND HE PUNCHED A WALL UNTIL HIS FINGERS BLEED.) I don't know how to unlock a lot of costumes, like deadpool, just kill a lot of people and then try to do what you said again when it says that you unlocked a new costume and dossier on a little blip thing that appears in the middle of the top of the screen.
