Several hidden messages have a chance to appear, some in a garbled form, at the bottom of the screen upon beating the game. They were added in certain revisions of the arcade version of the game to fuel rumors and increase the number of quarters spent. These messages are:

• Who Is Smoke?
• Where Is Sonya?
• Who Is Jade?
• Where Is Kano?
• Friendship?
• Where Is Goro?
• Babality?
• Ceamr Odse Nto Exits (Ermac Does Not Exist)
• Emro Batmok Ot Meok (More Kombat To Kome)
• Sruep Ghih Miptac (Super High Impact)
• Three Rae On Stniiiaamel (There Are No Animalities)
