Quoted from Lermods:Thx, I have a lot to learn, have the game less than a month, it's so fast and furious, hard to keep track of what's going on. My main strategy has been to hit the snake, cross and sparky and then hit the strobing shot followed by the coffin hurry up. I hit a couple of those and the CIU lights.
CIU lights by completing the set number of grave marker, electric chair, snake, and coffin. (15 each is factory, it's adjustable in settings)
All but the coffin can be completed by lighting the insert at other shots, then making that shot. The coffin can only be completed at the captive ball. The tutorial video shows how to light the other inserts so your favorite shot makes progress towards CIU.
