Drain opponents health
After putting in the code for level select begin a fight. Hit your opponent 1 time and after that you can hold down the L and R buttons to drain his/her health! You must hit your opponent at least once for this to work. The only way to get rid of this code is to delete the Samurai Showdown memory from your 3DO system.
