Precise Striking

Get at least three 15x swoops in a single life
During one life, make three separate laser attacks that each build a chain of at least 15×. Let a dense red group approach the middle of the screen, then hold while the beam clears the reds. Release before it reaches any blue citizens. Watch the increasing hit-chain numbers to confirm a 15× attack, then release and repeat on two more red groups.
Protect the same life between attempts. Shooting a blue citizen or letting a red enemy reach the cannon ends the round. If that happens before the third qualifying attack, start another round and rebuild all three. The external PS4 demonstration (PozerMobile, 1:00) shows the requirement and pack timing.
