"Cara Mia Addio" is a famous piece of video game music composed by Mike Morasky for the 2011 puzzle-platform game Portal 2, developed by Valve. It is often referred to as the "Turret Opera" because it is sung by a group of sentry turrets during a pivotal scene in the game. The melody is a beautiful, melancholic aria in Italian, which contrasts humorously with the game's sci-fi setting and the turrets' typically lethal purpose. It has become an iconic piece within gaming culture.
