Quick Time Event

Quick-Time Events (or QTEs) are a gameplay mechanic featured in the Lords of Shadow franchise. These involve the player pressing a certain combination of key presses in an animation-driven sequence. Most QTEs occur after a boss battle.

Gameplay
There are two types of QTEs in the reboot franchise; the first is a typical button-mashing, while the second forces the player to time a certain key press with the graphical aid of a circle. A successful QTE either guarantees a kill, or triggers the next phase in a boss battle. Otherwise a failed QTE will have the player character damaged, and the enemy having its s restoring to a certain percentage.
