You are now in the Crane Control Room. It will ask you to enter the
code to control the crane. Enter XA and the crane will move the barrel
blocking your way, then enter BB to move the second barrel. Now go to
the room above you and then right, down and exit that room. This time
go left and down the ladder. Go west through the path where the barrel
was originally. Enter the door at the end and you will see a computer.
It will tell you the code to the Main Part of the Factory. The code is
ZABIE, and translated into XABY. Exit the room and then go right, up
the ladder, right, and down all the way past the bridge. At the end
enter the door, go down the ladder, then left and up to the door. Get
on the conveyor belt and go right. Exit on the next stop and get the
chest. Then get back up on the conveyor belt and go right until you
stop moving. From here hold down on the keyboard or control pad. Now go
east, up, climb the ladder, and up again onto the green elevator. It
will take you to the top, the main entrance of the Factory. Go down and
left, and fight the Debuggers. Then go left and up on this elevator.
You will go down a level. On this floor there is a Save Point near you.
Save, then go left and up. Through the door there is another computer,
access it and an opening will open on the right. You will also fight
Acids and Alkalines. Alkalines are the same as Acids, but have 1 less
HP. They are not as dangerous as Acids. Go into the hatch on the right
(what you opened) and climb down. Now go left in this room and keep
fighting Alkaline in your way. At the end of the room go down through
the door and fight the Acid. Go down through another door and then
east, another Acid and Alkaline group block your way. Defeat them and
go through the door above you. In this room go to the computer on the
top right and that will shut down all the lasers. You will also fight a
bunch of Alkaline and Acids. Defeat them all and then grab the two
treasure son both sides of the room. Now go to hatch in this room on
the bottom left. Enter and go right, then up, if you keep going right
it will take you to an elevator, which is basically a shortcut to the
surface. So keep going up and you'll see a locked door. Go to the left
and on the computer it will ask you to enter the password. Remember it?
It's ZABIE, so enter XABY on your keyboard or controller (on PSX, it's
the same, just replace the letter buttons with the shape buttons). The
locked door will now open, go through it and Robo will look at the big
Lock Computer. He will shut it down, but an alert goes up and now you
have to run!
