Spinning Under Water
If you hold L1 and L2 for a little bit of time and then release both buttons at the same time while under water you will do some spins under water.
Destroy The Coast Guard
Easiest way to do this is to jump out of the water and kill the gunners on the ship. Then the ship will still follow you but it can't hurt you. Next destroy a little sub thing and pick up the box that comes out of it. Throw the box into the ship to do damage. The ship usually takes about two hits. Also there will be two helicopters. To destroy them jump out of the water and grab onto them. I destroy the helicopters first then kill the gunners then destroy the ship.
Killing Humans On Land
If your faced by a target hiding somewhere out
of the water all you gotta do to reach em is aim
your head out of the water and press circle. Then
repeadetly pres R1 to snag them.
Unlimited Easy Points
When you advance through the game a little bit
you will need points right? Well here's how to
get them. When you start trouble police boats
will come and you will want to destroy them.
When you destroy a police boat it will give you
2,000 points and each time you destroy a police
boat more and more will come. WARNING: THIS ONLY
WORKS WHEN YOU DESTROY POLICE BOATS. Go0d Luck!!!
