Fight hidden boss

To fight the hidden boss at the end of stage 3, you must finish the stage without dying and then finish the original boss at the end of the stage off with either a special move or a bomb. After the point total is tallied for the stage a new boss will appear.

Second loop

To unlock the second loop you must collect envelopes dropped by various King of Fighters characters in the five stages of the game. The first four can be collected during any playthrough and as long as you've done this, you can get the final one using stage select. When you go to collect the fifth envelope, you must finish the entire stage and boss without dying. After this is accomplished you will play through all the stages again on a harder difficulty and there will be an alternate final boss after the boss of the fifth stage is complete.
