My view; take Ironman. You have the 'IRON' targets on the left, one shot
You then have the spinner, shot 2
War machine is shot 3. This is a hard one to make so you don't want too many of these
Left ramp is shot 4
Center spinner shot 5
Whiplash , shot 6
Right ramp, shot7
Right spinner, shot8
'MAN' targets, shot 9
I would not count the DRONE targets as shots
And I suppose if you count the 4 drone targets you are up 13 - magic number.
Thanks for your view - helps
