Aldo returns to the compound to see Tessio held at gun point. Tom explains Tessio had set Michael up to be murdered - he had arranged a meeting between Michael and the Barzini family at which Michael would be killed. Aldo heads to the meeting with Tessio, killing the Barzini assassins and then killing Tessio. Michael then summons Aldo to a church in Little Italy where he is acting as godfather for his sister's son. During the ceremony, Michael has Aldo assassinate the heads of the four families—Victor Stracci, Carmine Cuneo, Philip Tattaglia, and Emilio Barzini. With the aid of Clemenza, Willi Cicci (Gavin Hammon), Rocco Lampone and Al Neri (Terence McGovern), Aldo carries out each hit, finally avenging the death of his father at the hands of Barzini. Michael then promotes Aldo to Underboss. If the player keeps playing at this point, and Aldo bombs all four rival family compounds, he is promoted to Don of New York.
