Godfather 2

- Get the diamond smuggling crime ring bonus as soon as possible. This will give you kevlar vests and most importantly will take them away from everyone else. You have an instant advantage, right there.

- Also, bombing a building is a very easy way to clear out guards for an easy takeover. A successful bombing will kill everyone in the building (including the shopkeeper) and will put the building out of action for a while. Once it reopens it will usually be completely unguarded so you can waltz in and take it for your own.
