the title says it all.
so please,help!

Sub-Quest 5: Explore the Ruins!
Items: See map
Bosses: none

I won't write a walkthrough on this. However, the maps in this FAQ will help
you explore. Anyways, you should gather all of the items. Remember to equip
the Drill Arm! Also, the Mystic Orb and Marlwolf Shell can make the Shield
Arm (y'know...while you're at Roll and everything...I thought I might mention
it), the Plastique will make Power Blaster L, and the Bomb will make Power
Blaster L, the Flower Pearl and Gattling Part were used to make the Gattling
gun.

Once you have all of that, go to the Uptown Museum. Give her all of the
items that you have. That should be all of them. Exit this floor, and re-
enter. You can see everything that you donated now. Also, talk to the girl
in the green dress to get a Prism Crystal. Trust me: There is a good reason
you got this. Now have Roll run item development to get the SHINING LASER,
the most powerful weapon in the game. Upgrade it as much as possible, then
save, and then go back to the Main Gate. But first...SAVE!

Work your way down to the room with the Cerberus in it. Equip Omni-Unit
Omega, Machine Gun, and Gattling Gun. From this room, go out the door to the
right to get a Generator Part, and then go to the left door. Go through
these doors, and you'll be behind the fence of the Old City. Enter the
Warehouse. After another humorous scene with the Bonnes, you fight the
hardest boss in the game...

BRUNO

As soon as the fence breaks down, RUN!! He shoots bomb from his legs. He
has those plasma shoots, and he breaks buildings down just by running in to
them. This battle is easier with the Buster instead of the Shining Laser.
Also, hide behind the black portals. They cannot be destroyed. Not much can
be said about this battle...just remember to watch all parts of Bruno's body.
Remember, cartwheels are the best way to avoid the plasma. Also he shoots
rockets from his shoulders. Aim for his head and mid-section. Also the
laser can work really well if he is close, and you are on a building.

Once he is gone, you can enter sub-city #1!
