Unlock all Alternate Costumes to get the You've Got Style! Trophy and Achievement. The Costumes can be unlocked in two ways. You can whether buy them in the Krypt or complete Ladder Mode with the fighter. The 3rd costume of Scorpion was unlocked with a promotion code and is not required. The 3rd costume of Mileena can be gained by beating Challenge #300 in the Challenge Tower (or by spending 50.000 Koins to skip the last Challenge). This one is not needed as well. Keep in mind, that the Alternate of Kratos can't be bought. On PS3, you have to finish the Ladder at least once to unlock the Costume. Moreover you have to visit each fighter in the Nekropolis to make the Trophy pop. Cyber Sub Zero has no second Costume, but Quan Chi has one (you get him by finishing Story Mode).
