Quoted from vireland:
So it's not random? I knew it was connected to the shields, but I always thought the award was random. I would always milk the shields for awards, and it seems like it would take more than two before EB would light on the left ramp.
Not random if you have it set up with factory settings. It's tough to get the EB but doable.
I'm always going for Bogey though, so there are plenty of ramp shots and rollovers to light the shields.
The first collect during Bogey is 30 seconds more time. The second shield collect after that is EB. You don't have to have Bogey running.
