Ratchet & Clank: Up Your Arsenal/Walkthrough

There are a lot of planets, so be prepared for a long journey. As Ratchet advances, the planets will become steadily harder, but luckily you will be provided with more weapons and armour to assist you in your journey throughout the galaxy.

Veldin

 * A muddy and backwater planet that happens to be Ratchet's home planet. It is slowly being destroyed by the Tyhrranoids, unless you can stop them first.

Note: Once you complete this planet, you cannot return to it for more bolts.

Florana

 * A jungle planet that is inhabited by Floranian Blood Flies, Floranian Natives and Floranian Swamp Beasts. Also, don't swim in the swamp, unless you are in the mood for getting eaten.

Starship Phoenix

 * This is the pride of the Galactic Fleet. It's equipped with the latest technology, including a holographic training center, armour and weapon vendors (you can test run weapons you haven't purchased in the training center), a starship customization system and a VG9000 games console, which you can play Vid-Comic disks on.

Marcadia

 * The presidential planet, it has a lot of fancy buildings made of rock. Or it did, before the Tyhrranoids showed up.

Annihilation Nation
One of the biggest (and most deadly) gameshows in the Solana galaxy, you can return here many times to earn prizes and lots of bolts.

Aquatos
A planet entirely consumed by sea, it also happens to be home to Dr. Nefarious' lair.
