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.
- Extra Dino Duel dinosaurs
Purchase Rick, Gail and the Tank for the "Extra Crisis" games. Another set of dinosaurs will appear at the character selection screen for purchase.
- 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.
- 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.
Instead of buying the best Recoveries, buy the Hemo Pack and the Small Med Pack. This will save money. When you have enough money, buy the Armor. It will stop the bleeding.
- Triceratops and Compsagnathus
Purchase all the other characters and dinosaurs for the Dino Coliseum and Dino Duel. The Triceratops and the Compsagnathus will be unlocked in hard mode.
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.
