Fight the Mayor:
When fighting the Mayor keep diving at him repeatedly. This will get him winded without him being able to land many if any blows on you. When he gets winded he will double over to catch his breath; when he does rappidly tap X and Circle alternately this will choke him out and cause alot of dammage until he shakes you off. Then repeat untill he's toast.

When fighting Fahook in the second cargo hold; keep shooting at him while traveling in a circle from front to back of the cargo hold. At the front you will find an AK and at he rear by the open bay you will find an M4 (be careful not to get too close to the open rear of the plane or else you go bye-bye...). You will notice that Fahook keeps drinking from a bottle and spitting flames or recovering his health. As he is drinking you will see the red target around the bottle; when you do you must manually target the bottle(R2 & annalog)shoot it out of his hands enough times and the bottle will break and then Fahook is easy prey.
