Get the third Energy Key Card early
Before leaving the jungle, you can retrieve the card from the shallow stream. This way you will not have to make a return trip after finding out that it is needed.
When killing Raptors with Dylan's Shotgun, you can save ammo by waiting for the Raptor to jump up in the air towards you. When it is in midair, blast it away. This move only consumes one bullet instead of the standard two or three.
Twin submachine guns
Instead of investing in the heavy machine gun, purchase the Twin Submachine Guns, and upgrade its amount of ammo. It is more convenient than the Heavy Machine Gun because of its dual target capability.
When using submachine guns, do not hold the button down. Only use one shot at a time to do more damage and save ammunition.
When dealing with the first Allosaurus on your way to the facility when you are first using Regina, purchase the Flamethrower and go to the ledge that leads nowhere towards the west. Every time it approaches you, burn it. This way, it can be killed easily and you will get a large No Damage bonus.
When playing as Dylan buy the electric weapon for 18,000 points. When you encounter the blue raptors, fry them with about five shots.When you kill the raptor you get 7,000 points. When playing as Regina, use the Rocket Pod Launcher which will require ten shots. Note: Buy the gold card -- it doubles all points.
Make Ultra Raptors appear
Make a combo with at least 20 hits. Exit the area. Enter an area where Raptors usually appear, such as the Jungle. You will instead be greeted by two Ultra Raptors.
When you get to the part where you see the first helmet person, stop. After the intermission reload your ammunition using the PC. Go out the way you came in. Shoot the raptors and keep switching screens so that more raptors will appear. Keep killing them while trying not to get hurt. After awhile, exit through the same gate. if you did not get hit, you will get 6,000 or 2,000 extra points depending on your combo and how many you killed. Stock up an ammunition and repeat. You will soon have enough money to by the EMP gun and ammunition. The raptors will stop appearing after awhile -- go to a different place and do the same thing.
When you get the third energy disc, go back to your boat. Fight off the sea creatures, and go to the third energy plant. When you arrive, there will be a group of the sea creatures with the long necks. Purchase the heavy machine gun and it will take only one shot to kill them. Do not get hit and exit the room after killing all that appear. You should get 20,000 or 30,000 points. Repeat this in all the rooms from there on until you go underwater in the energy plant. You will have enough points for whatever you want for the rest of the game. If not, just return there and kill all of them again.
