Design Disc code:
When at the part of the game where this sound is heard after pushing the shelf,
enter "367204" as a code.
Since the dinos can not pass through a shutter, use them to your advantage. Close
each shutter after you pass them. This way, if a dino appears in that particular
area, you can not be attacked (unless, of course, you are on the same side as the
There are some areas that you will only pass through once or twice in the entire
game. Killing the dinos in these areas is pointless; more importantly, it is a waste
of ammo. Use the weakest tranquilizer dart on it/them, and move on. This way, the
bullets/shells/slugs/grenades are available when you need them. Once you get
unlimited grenades (by completing the game three times under the normal difficulty
setting), you can kill those dinos, without wasting ammo.
When at a puzzle, before changing it, around push the button. Nothing will happen,
but if you watch the colored lights they will turn on in the order needed to solve
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.
View Ending 3 without agreeing with Rick:
It is possible to get Ending 3 after agreeing with Gail. When the game prompts you
to agree with Rick or Gail at the end of the game, choose Gail's decision to go
after Dr Kirk. After the intermission sequence, go out the main door of the room.
Go across the room to the double doors that lead to the Central Stairway. Once in
the Central Stairway, if you have the infinite grenade gun, kill the two dinos in
the room. If you are low on ammo and do not have the infinite grenade gun, try to
run around them and not get hit. Go all the way to the end of the hallway to the
Security Level A door. Go through that door, which leads to the Port Transport
Passageway. Get on the slider and go across to the other side. When you get there,
get off of the slider and go through the large sliding door to the Heliport
Transport Passageway. Get onto the new slider and go across to the other side of
this area. When you arrive, you should see a large door in the middle of the wall
in front of you and a small Security Level A door to the right of it. That door
leads to the Underground Heliport. Enter the Underground Heliport through the
Security Level A door as the Large one will not open. Walk forward until you see a
sequence that shows the helicopter. When you regain control of Regina, exit the
Underground Heliport. Go back across the slider closest to the Underground Heliport.
When you arrive back at the other side, do not go through the large sliding door to
your right. Go through the large door in front of you. The room you enter is the
Transport Passageway, not the Port Transport Passageway. Be careful, as a dino will
attack you. Kill the dino, then walk forward until you reach the Security Level A
door that is on the right of the screen. Enter through that door, which leads to the
Special Weapons Storage. You will find Gail and Dr.Kirk. The intermission sequence
will take you back to the Underground Heliport. When it completes, go back out the
door to the Heliport Transport Passageway. After that intermission sequence, kill
the T-Rex. When he is defeated, Ending 3 will play and you have successfully viewed
it without agreeing with Rick.
