What strategy did you use on this mission? I got wasted a couple of times and was getting frustrated. I didn't want to use cheats (cause thats for wussies
) so I tried this:
When you chase Lance up the stairs, don't go up to the helipad. Instead run downstairs and out to the backyard. Jump in the Sea Sparrow and fly on up to where Lance is and lace everyone with the Sparrow's machine gun. Then go back to your safe and wait for the mafia. After they show up, run like mad back downstairs and exit out the back. Go around front and blow up the limos (and any mafia guys) with your rocket launcher. (grab fresh armor too) Then run up to the front door and shell the crap out of Sonny.
