Sundowner Boss Battle - No Damage S-rank - Revengeance Difficulty

Wanted to record a decent/good run of Sundowner. The lock-on mechanism can be a pain, so the second helicopter has caused many a failed No Damage runs. For anyone unaware, the requirements for S-rank in this battle are: - 5 minutes or less - 400 BP - 2 Zandatsu - 3 kills - 50 hit combo Since No Damage gives you 2,000 points, I choose to ignore the Zandatsu requirement and simply kill Sundowner in his 2nd phase before he has a chance to call the soldiers in.
