* Unlocking the standard second loop, otherwise known as the ''omote'' loop, which requires completing the first loop with the sum of bombs used and lives lost being no greater than 6.
** At Anime Expo 2014, during the ''STG Weekly'' panel, one of the panelists achieved the ''omote'' loop '''[[http://www.youtube.com/watch?v=zPpaqcgAodA in front of a live audience]].''' Even more impressive is that it was his first time doing so!
* Even better is the special second loop, aka the ''ura'' loop, which requires a ''[[NoDamageRun no-miss]], no [[SmartBomb bomb]]'' run AND at least 120 million points. The game doesn't say "WELCOME TO SPECIAL ROUND" for nothing.
* Complete the ''ura'' loop and [[TrueFinalBoss DOOM]] will appear. If you can take him down, congratulations, you are one of the best ''Ketsui'' players in the world.
