I assume you are asking what the alternate costumes are for the Mercenaries mini-game. For Mercenaries 3D, you will have to consult someone who is not me. In RE4, however, Leon and Ada are the only characters with alternate costumes. You must hold these buttons when selecting your character (Note: this is for Wii.). For Leon: A & 1 = Leon with jacket; A & + = Leon's R.P.D. outfit from Resident Evil 2; A & + & 1 = Leon's gangster suit. For Ada: A & 1 = Seperate Ways dress; A & + = Assignment Ada outfit. Krauser, HUNK, and Wesker do not have alternate outfits. Hope this helps!
