Extra Health
Some mini-game within "Jurassic Park III: Danger Zone" allow you to play as a velociraptor. Playing as a raptor gives you access to special areas. It also makes you fast, strong and lethal. The other raptors you encounter, however, will be just as strong as you, unless you enter the cheat "MORE MEAT PLEASE" into the Password menu.
Extra Fuel
When driving around in your Ford Explorer looking for lost DNA vials or searching out new DNA from live specimens, you might find yourself low on fuel. If this happens, you will lose a life automatically and start the stage over again. To avoid this happening, input "LOW FUEL LIGHT" into the Password menu.
Max DNA Meter
To complete the main quest of the game, you need to fill the DNA Meter in the main menu screen. Because so many diverting mini-games exist to distract you, you might not find yourself getting around to this any time soon. If you want to fill the meter and leave yourself more time for fooling around, simply type "ALL DONE NOW" in the Password menu.
Turbo Jeep
If you're getting chased around in your Explorer and make a wrong turn, it might be your last. If you fall off the main road, your jeep will stop, leaving you vulnerable for several seconds. Even once you get going, the jeep sometimes just doesn't go fast enough. To avoid becoming T-Rex lunch, put "SPEED BOOST" into the password menu.
