Luring enemies:
On missions where you must kill your enemy in a certain way such as throwing them off of a roof, first lure them over to it by avoiding them and they will come to you. Then beat them up a little bit, grab them, and swing them so they have their back to the hazard. Move forward to shove them.
Ammo at safe houses:

“The Don Is Dead” mission tip:
In the barber shop, break the windows in before starting the mission. Once the Don is shot you will be able to easily shoot through the window.
Marlon Brando’s last appearance:
Marlon Brando makes his last appearance in the game at the mission where you protect the Don at the hospital. After you kill the assassin and Michale Corleone tells you to go to the basement, go forward and turn left. You will see Michael Corleone talking to Vito Corleone while he is in the hospital bed. This is Marlon Brando talking, which was recorded while he was hospitalized.
