Well, there are lots of random things in the game so what
might work for me wont work for everyone cause I am not
entirley sure what parts are random.
Part 1 - USA
Professor Jones at Barnett College
In the beginning, you can go box if you want by going
to your locker room. Then go out the door and talk to
Marcus. Ask him about the guy's situation and the new
archaeologist. Then go back to the 1st door you saw and
open it. When inside, tell the kids you have a solution
for everyone and for the secretary to take down their
names. When inside your office, pick up all the junk mail
and papers to get the package. Open the package and there's
the grail diary! Then leave by the window.
Then go to Henry's house and go to the bedroom. Pick
up the painting of the trophy. Go back to the living room
and pick up the plant and table cloth to move them. Then
go to the leaning bookcase and push it. Get the tape on
the back of the bookcase. Go back to your office and use
the jar of liquid on the tape. Go back to your dad's house
and open the chest with it. Get the old book and leave
Part 2 - Ahh, Venice !
In the library, go to the lower shelves to look for books.
Keep going to the lower shelves until Mein Kampf, biplane
instruction book, and a catacombs book are found. Mein Kampf
is the leaning book, the biplane book is black and in a
how-to-do enclopedia like series. The catacombs is a yellow
book in a series about maps of ancient Rome. Now go find
the post and red cordon and pick them up. After that, open
the computer version of the grail diary and it will show
a window and tell what plaque to look at. Go find the correct
window and look at it. It says it's the correct window.Now
look at the correct plaque and use the post on the slab
with the roman numeral from the plaque.
Now look at the book about the catacombs. The top map is
the upper level which you're on and the lower map is the
bottom level. The sections where it shoes a closer view
of Indy are the round looking parts which connect tunnels.
Find the nearest one from the one you started from and go
there to pick up the skeleton's arm/hook. Now keep going
till you come to the manhole. Go up it and look at the wine
bottle near the lovers. Get the wine bottle and use it in
the fountain. Go back to the torch you should have passed
along the way to get to the manhole. Use the bottle on it
and pick it up. You should have fallen into a passge. Go
right and choose the room on the right. Keep going past
the bridge to look at the inscription. The inscription will
narrow the grail choices to 2. BE SURE TO WRITE THEM DOWN.
That is very important for the end. Now go to the plug and
use the hook and whip on it. Go to the room on left and
climb the ladder. Then go right and go to the room to the
southeast where water use to be until the plug was pulled.
Continue along the passage. Go north into the machine room
and use the red cordon on the machine. Then use the wheel
to operate it. Leave and go east and north and east again
to a room with statues. Use the computer grail book again
and push the statues to correct combo. Enter the door and
go in a westerly direction past the bridge and skeleton
room. In the next section go northwest to the skull playing
room. Look at the computer grail book for the correct notes
and play them. Enter the door and continue to go in an easterly
direction to the tomb. Open the tomb and look and then go
to the lock and pull it. Leave to the castle where your
Part 3- Finding your father
Once in the castle, ask the butler if he has relatives
near him and till him Otto sent you but he is ok. Then say
you have proof you are telling the truth. Go north to passageways
and go south then east. Choose the lower door on the east
wall. Talk to the drunk about everything except don't say
he's drunk. After getting the stein from him, go to the
next door in the hallway just above the one you're in. Once
there, get the ale from keg and use it in the fire place.
Get more ale and get the roast boar after it cools off.
Go back to castle entrance and go to the hall. I am not
sure if the guards are random about what you can say to
keep from fighting them. I will tell what I said. Go to
south hallway and tell the guard you have come to interrogate
the prisoner, you are Gestapo, and ask if he's leaking information.
Then go to 1st room on right to get servant uniform. Then
go to room on left and push the suit of armor in the far
right corner. Leave and go to north hallway. Tell the guard
you're selling leather jackets for $15 and you have authorization.
Go upstairs and go south and east. Enter the north door
and open the trunk to get money. Then wear servant uniform.
Walk south to the guard and give him the painting. Watch
the cut-scene about the painting and change back to Indywear.
Now go to east end of hallway and north. Enter the door
and open the trunk for the uniform. Look at the uniform
to get the key. Go back to where you got the servant uniform
and unlock the officer uniform. Go back to where you found
the key and wear the officer uniform. Now go north to hallway
and walk east. Tell the guard you are on official bussiness
and new here. After asking for authorization, tell him to
go talk to the colonel. Go south and enter the room on west
side. Get the 1st aid kit and leave. Go north and west till
you can go west no more. Go north and enter the 1st door
you come to. Tell the guard you're on official business.
Leave by the way you came in and continue on. Go north and
enter the door farthest right. Tell the guard you're on
official business, you're new, and when he asks about you
ask him if he has clerance. Open the door and enter and
open the window. Go outside and walk to the 3rd window.
Open it and enter. Push the loose brick near the window
and go back outside. Use the whip on the brick and enter
the 1st window on 3rd level. Open the cabinet to get money
and come back for your father later. Go back to 2nd level
by pointing the arrow at the 3rd window. Once inside, wear
the officer uniform. Open the door and go to the door on
the far left. Give Mein Kampf to the guard and use the stein
with ale on the grating. Leave and go to the stairs leading
to 3rd level. Go to the 1st door you find. Before entering,
tell the guard he has wrinkled pants, a stain, and for the
buffoon to get out of your way. In the office, give the
roast to the dog. Get the trophy and open the cabinet to
get the pass. Go back to 2nd level where you gave the guy
the painting. This times go to the room on the far left.
Go to the Mona Lisa and move it. Open the vault and go in.
Look at the painting. I couldn't tell anything except it
made the grail seem to be a bowl. Not sure though. Leave
and go to the ale place and fill the trophy with ale. Be
sure to change uniforms before 1st level. Go back to 3rd
level and give the trophy to the big strong Nazi. Go south
and tell the guy the same thing you told the guard about
the security clearance. Go west and north into a room. Get
the key there and go back east and north. Unlock the door
your father is in and go to any guard. They will capture
you and put you tied up in chairs near the knight in armor.
Have Henry push the chair so the space between the 2 chairs
is at the mark you made earlier on the carpet. Have Indy
push the armor. Once free, push the top statue and leave.
Go the motorcycle and talk to the guard at the guard post.
Tell him you are a superior officer on a top secret mission
with no ID.
Once in Germany, have Hitler sign the passcard that had
the combination on it. At the airport, have Indy ask the
man about his grandchildren. Then switch to Henry to steal
the tickets. Leave and go to the biplane or the blimp. Know
what to do from the book if you decide to use the biplane.
You don't have much time. If you go to the blimp, give the
man your tickets. In the blimp, have Henry put a coin in
the piano man's cup. Then have Indy enter the door and push
the radio. Fight the guy and open the cabinet for the wrench.
Leave and use the wrench in the hole and turn it. Save the
game before hand. Climb the ladder and run from the guards.
Go up the ladder in the top left corner. Keep going up the
ladders to 3rd level. On 3rd level run to a different ladder
going down. Go down to 1st level and this time you'll go
to the biplane. Henry will already be there. Fly around
and dodge the plane. Just don't let them shoot ya down for
a while. After crashing, choose the expensive looking car.
Give the pass to the guards at the guard posts.
Part 4 - The Grail
Once outside the grail temple save the game for the last
time. Once inside, go to Donovan and go past the 3 trials.
If you die on the trials you will have to start over from
the 1st. The 1st trial is tricky. You have to get Indy to
go more south or he will get cut all up. The 2nd trial is
easy. All you have to do is step on letters that spell out
the word Indy keeps saying. Just wait till he says the word.
For the 3rd trial, immediatly possition the pointer over
the cave to the right and press return to go there. Once
inside, you must choose the correct grail from the written
version of the grail book the game comes with and use it
in the water. Then you can pick up the grail after rescuing
your father and give it to the knight. You can also give
it to Elsa and look at the seal once it is broken to use
your whip to get the grail back. Be sure to give it to the
knight. After that, the game ends!
Good Luck !
