The assists we saw were his old db+2U and his db+1U from MKX. It probably won't happen, but wouldn't it be crazy if his assists had that same style of variance like in MKX? He could have high shatter, mid shatter and low shatter on an ambush assist(which won't happen, since a low hitting ambush assist would be crazy), and the uppercut, the overhead launcher and the straight punch all in a summon assist. I think it could be done by doing something like neutral kameo button for the normal assist, or input kameo then hold down/up for the variants. I don't think we have a kameo that works like that yet, so Tremor would be great for that.
