Quoted from TaylorVA:collect shot is through the forest behind the crystal ball. There is a collect insert there. Right now the modes are just scoring ones,i.e., pops, targets and such.
The Collect he's referring to is the one for HOADC. That Collect is behind the right, side flipper. The ball goes back into the shooter lane. It's a pretty tough shot, at least for me. I'm getting better at hitting it both with the left flipper and backhanding it with the right. Still not good but getting better.
