"Tell Mike it was only business. I always liked him."
Salvatore Tessio

He liked him so much that he betrayed him.

Salvatore Tessio was one of Don Vito Corleone's most trusted friends and also his Caporegime.

Ultimately, Tessio arranged for Michael Corleone's assassination at a peace summit set up by Emilio Barzini, who had become the strongest Don in New York.

In the game, Tessio is executed by Aldo Trapani, after, when arriving at the Embassy Club, he attempted to escape. His final words were: 'It's just business I tell you. Only business.'
