How to use: Go into a private match and DON'T CHANGE THE SCORE LIMIT OR TIME LIMIT OR ELSE THE CODE WILL TIMEOUT. Press Home on Wiimote to activate the code when the game is loading and the gametype might change (don't worry). The game lobby might be unusual (there would be bombs, flags, messed up teaming, etc). Kill people or have a friend let you kill them. The private match will be treated as if it were a public (xp counts, custom classes, game ends if no enemies, etc). Every kill you get will count 4 times xp. Enjoy ranking up a little faster!
This code is tested and confirmed working.
