Ok I know that Nobody is really interested, but going through the game cases I had leftover from the video store I worked at that closed, I came across a code for GI Joe: The Rise of Cobra that is a pre order bonus to unlock the "classic" uniform for Scarlet. Instructions are as follows-
1. Go to title screen or main menu
2. Use controller to enter code
3. Enter appropriate code for your console
PS3/PS2/PSP- directional R, U, D, D, triangle
Xbox 360- R, U, D, D, Y
Wii- R, U, D, D, + Button
4. Listen for "Yo Joe!" or sound effect when character is unlocked.
This should work multiple times, so share with all your friends (that like crappy games)!
