Say I want to make Freddy Krueger's fatality, which is called Welcome To My Nightmare
down, up, left, right + block
When I finish pressing the buttons, it didn't do the thing, since I'm already in the air when I press up and fatalities must be done on the ground.
I have no problem when the jump is right at the end of the combo, since it's the last directional button I have to press plus any "hitting/block" button.
But I always considered fatalities that involves the up button, the ones which are not at the end of the combo, as the impossible ones... unless there's a trick for them. Does someone know?
