Hey man I think you have some of the rules confused. There is no mode stacking. The #1 target is not a Playfield multiplier but a bonus multiplier. LDG is an add a ball multiball. Must add 5 balls to beat. 1000 corpses is main multiball. Beating other modes leads to a multiball or an option of one. Murder ride is now competed by collecting all three murder cards at anytime. What and red hot are linked together. The rest I believe are independent at this point.
Glad another person is enjoying it as well though.
