Easier time killing enemies with lives
During story missions where you have to destroy an enemy with a certain amount of lives start with saveing a position after each time you kill them. If you die, load it and continue. You will load with full health and they will be missing a life. This works well for fights with the gambler and others.
If the cops are after you and you cannot lose them, go to Rusty's scrap yard. When you land or park, the cop will give up looking for you.
