yeah, my friends (the ones I still play with are the ‘need sentries’ crowd from GoW4, not the ‘decoys and lockers only’ crowd
) and I unlocked all of the daamge modifiers on all fathers, and last night we started working on training grounds… We finish with extra health and extra lethal (those are tough, I find), next time we’ll do ironman, and then work on the higher ones…
yeah, i hadn’t realized until recently the modifiers were unlocked PER MAP 
Question: if we just jump into wave 50, and finish that, would THAT unlock/complete the damage modifier(s) we select? Or do we need all 50 waves for that?
wait, what?? Torque and drop will hurt the Matriarch regardless where they hit?
