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.
Counter-attack
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.
Allosaurus
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.
To kill a Allosaurus easily, buy the flamethrower and keep aiming
at its head. It will eventually die and give a large no damage
bonus if you did not get hit.
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.
Saving money
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.
Counter a sudden rear attack
To counter a sudden attack from behind, instead of
pressing "Turn Around", just press "Aim" while auto
aim is on. This will save time.
