If you are stuck on the final mission, all you have to do is complete a total of 96 missions to finish the game. In order to unlock the bonuses, backtrack to an incomplete goal (for example, the first chapter), and you will see the videos. This
works especially well if you are completing sick mode, considering the final challenge has a considerably shorter period of time to finish. Note: You must have completed the game once beforehand to be able to skip it the next time.
