Quoted from Killermarmot:Amazing Run.
Maybe dumb question but I can't figure it from your video or the rule sheet, is the annihilation bonus triggered from the same spot for each of the attacks? Like is the tank bonus in the same spot every time or is it just an additional random tank shot? Is the only difference it's blinking and not solid?
Each one is different, after Tank MB a single random tank insert will be lit for an annihilation bonus collect, once that is hit another tank insert will light until you move out of the city.
Powerline is similar one of the standups will be lit to collect and it will move to another one.
Bridge is where it gets a little different, once bridge MB is complete you need to collect a certain number of switch hits, I think around 40, that will light the captive ball/magna grab to collect the bridge annihilation bonus. That is why its good to use GZ and Mecha MBs to collect these as you just need to rip spinners and hit the captive ball as much as you can. If you have a really good bridge you annihilation bonus will be larger that regular jackpots and once you've completed multiple city actions that value is multiplied to the point it might be worth more than come GZMB super jackpots.
