Go to the teleport pad in Metrapolis between 3:00 a.m and 3:59 a.m., or at any time if all
trophies are collected. Use it to reach the Insomniac Museum. The museum contains various
pictures, concept art, comics, design concepts, and more.

Successfully complete the game to unlock the "Sketchbook" option at the "Cinematics" menu.
Press L1 or R1 to move through the pictures.

Have a saved game from Ratchet And Clank on your memory card to have the Old School
Ratchet skin available at the Phoenix Starship weapon vendor.

Once the battle starts, take out the N60 Storm/N90 Hurricane and kill her backup dancers.
Eventually, she will appear in a go-go cage around the stage. Shoot her while dodging the
laser things until more backup dancers appear. When Ratchet depletes two thirds of her
health, she will step onto the stage and attack you as she did before, only doing the same
attack as the backup dancers in addition. Shoot her, avoiding everything she tosses at you
and you will win.

At the command center where you have to destroy the Bioblitorater, at the beginning of
the level you will see lots of tables, chairs, and umbrellas. When you see them, use your
jump attack (Jump + Circle) and everything will break. You will get about 5,000 Bolts. You
can do this many times, as the objects all reappear when you die. There are also other
areas in the level where you can do this.

To do this, you must have the Flux/Splitter to at least version 3 and the "Scorpio"
(or "Naptime") challenge. Go to Annihilation Nation and enter the Deathcourse. Choose
"Scorpio" (or "Naptime"). Once the challenge starts, equip the Flux/Splitter rifle and
enter sniper mode (L1), but do not zoom in. Then, press Circle to fire until Scorpio dies.
Do this until you have the desired amount of Bolts.

Have a completed saved game from Ratchet And Clank on your memory card. Go to any
vendor (Slim Cognitos, Phoenix Ship, etc.), then go to Gadgetron Employee discount. You
will then receive a 10\% discount on each weapon.

Press Up(2), Down(2), Left, Right, Circle(2), Square in any Quark Vid-Comic. Alternately,
press Up(2), Down(2), Left, Right, Circle, Square(2) in any Quark Vid-Comic.

Take out the N60 Storm and fire. When he throws his boomerang, move along with it (in a
circular motion). After one quarter of his life is gone, tribesmen will appear. Kill them
and continue firing until he is knocked out.

First, climb into the hover plane and shoot the Bioblitorator. It will shoot rockets at
you. If your ship explodes, you will drop to a turbo slider. Take the right bridge to
another hover plane to continue shoting him. Note: Take the left bridge the second
time and Quark sometimes will get in the way.

If you have weapons that have not been upgraded at all, you can easily upgrade them by
going to worlds with harder enemies. Use the weapons on them, and do not care about
getting killed. Repeat this, and you can get upgraded weapons easier.

The following skins can be used in single player mode:



Brainius: 6 Titanium Bolts

Bugnoid: 6 Titanium Bolts

Constructobot: 6 Titanium Bolts

Robo: 5 Titanium Bolts

Robo Rooster: 6 Titanium Bolts

Snowman Skin: 6 Titanium bolts

Trooper: 5 Titanium Bolts

Tuxedo Ratchet: 6 Titanium Bolts 

Start any challenge, then immediately quit.

Get the N60/N90 and fire away, dodging her swipes. When she latches onto the ceiling,
dodge the lasers and shoot the turret. After half of her health gone, she will shoot
missiles onto the ground. The fight will go into her point of view. Take out the
Plasma/Quantum Whip and run for your life. When you reach an alcove, jump into it and kill
any noids that attack you. When you exit the alcove, repeat the same process and blast her
with the N60. The turret on her back will now launch missiles now -- be careful.
