As soon as you get ability points, use them on Health first, then on Speed, Power, Accuracy, and finally Hunger in order. This order lets you get the best attacks and helps complete the free missions easier.
Angry Armada mission
Use the depth charges labeled in green on Jaws's radar, to destroy the Coast Guard boat for good. Earlier in the stage, when it says "Survive and kill everyone", destroy the helicopter by waiting for it to attempt to rescue someone, then bite it. Do not let go and you will drag it into the water where it explodes.
Attacking swimmers
When attacking a large number of swimmers trying to escape, attack them stealthily and drag them farther out so you have more time, then eat them.
If you grab a human, pull them deep underwater, let them go, then swim in circles around them, you will start to scare them as they resurface. Once they are at the surface, swim up onto them gently to lift them out of the water. You will scare them to death. This does not seem to kill humans that are on the surface already.
Blood On The Beach mission
Use the following trick to get rid of the Coast Guard ship that keeps shooting you, in front of the bridge and net blocking the lake. Face the bridge and swim at the battery on to the left. Jump out of the water and bite and hold the battery. Take the battery as far out into open water as far as it will go. When it disappears it will reset back on the beach and the boat will be gone.
Breakout Defeating Shamu
Enable the "1 million points" code then buy all your upgrades. When you reach Shamu use the corkscrew attack to knock him out. Then, keep biting him until he gets up. Keep repeating this strategy until he is defeated.
Cheat Mode
Start a new game and enter one of the following profile names to activate the corresponding cheat function.

All bonuses and 300,000 points - shaaark
1 million points - blooood
Never die - unstopable
Dead Of Night mission
In order to complete the mission you must grab and hold one barrel from the crew (who are dumping the explosives off the bridge) and toss it into the refinery pipe to the left of the dumping site. It should only take one of them.
Easy points
An easy way to get fast points is to go to the open ocean south. Then, go as far south as possible. Start attacking boats until police boats begin arriving. Attack them to rack up points. Using the Corkscrew attack is recommended, as it deals massive damage and almost certainly sinks the boat. Sinking the boats results in 1,000 points. Blowing the boat results in 2,000 points.
God Mode
You must get all 50 Treasure Chests sprinkled through-out Open Ocean West, Open Ocean South, Open Ocean East, Grand Occasus Canals, Underwater Caves, and Fisherman's Isle.
Launching objects
Try to grab mines, barrels, and buoys and launch them at your target.
To launch an item, grab it then press [Charge]. Release [Charge] and watch the item fly away. This is very helpful for destroying objects in the game. Just aim, charge, and release.
Level Select
Get all of the 45 hidden license plates in story mode. Enter Select at the main menu.
Predator In The Bay mission
When you get to the oil tanks, hit them with your head to destroy the machine guns at the top. Then, go under water and hit your head against the four pillars in the middle and the outside. They should fall and explode. Do this three times for all the oil tanks.
A much easier method (though it will cost health), is to take the torpedoes from the submarine on the bottom of the ocean floor. Hold them in your mouth while charging up your attack. Then, go to the pillar and slam your head into it. Do this three times.
To destroy the tankers without losing health, grab a torpedo near the destroyed submarine. Toss the torpedo at the big tubes that hold the tanker up. Do this to two tubes and you will destroy it. Make sure to destroy the turrets. To do this, bite the yellow orb above the turrets.
After you destroy the oil platforms, do not pick up any more torpedoes from the sunken sub. Instead, swim into the shipyard and find the grate in the water. Destroy it, and swim in. The metal door will open, allowing Jaws into the power generator room. Destroy the two metal tubes sticking up behind the turbine without touching the turbine fan. If you touch it, you will die. Then you must fight the Coast Guard ship. Use the same torpedoes that you used on the oil platforms and Brody will barely escape.
Thirst For Blood mission: Easy way around most of the mines
When you first enter, move to the far left and head down. Then, stay against the wall and move through. Next, swim to the next blockade of mines and do the same to it, or if you have your swim level maxed out do a charge out of water and go above the mines.
Thirst For Blood mission: Finding the divers
When the mission begins move directly forward and use the body slam to jump the mines. Do this a second time. Once you jump over the mines after the second time look to your left. Jump over a small field of mines and you will be in the area where you must kill the divers.
Unlimited health
Collect all 50 hidden treasure chests outside of story mode at the Open Ocean West, Open Ocean South, Open Ocean East, Grand Occasus Canals, Underwater Caves, and Fisherman's Isle. Save the game. When that saved game is resumed you will have unlimited health.
