To remix, duplicate anyone BUT Sam, and add your own characters, and change your name in the block, "my name is ( )." ONLY ADD 8 CHARACTERS AT A TIME. Then, go to the sprite "name" and add your characters names. MAKE SURE TO NAME THE COSTUME EXACTLY WHAT YOUR NAMES ARE OR ELSE IT WON'T WORK!!! And that's it!
Thanks to sam2028 for the original project Add yourself at Wipeout Minigame (Remix #0, 8 players).
