A lot of quick-time events can often be tedious interruptions that lead to failure -- tap a button too slowly and your sword may go through a wall instead of a boss; miss a button and your character might fail to revive itself. As a refreshing change, Ace Combat: Assault Horizon will see you using QTEs for less perilous tasks... such as gripping a fist.
We wonder what will happen if you fail the QTE, though... Does the fist not get gripped? It's a question for us all to ponder about.
