Real-Time Interaction

Quick Time Events (or QTEs) have been used in the more recent Sonic games (Sonic Unleashed and Colors).They are on-screen prompts with one of the buttons on your controller which you must press in time, or it will alter the game, ranging from just not doing as much damage as responding to the QTE, to resulting in the character's death, and losing a life.They usually appeared in boss battles.
