Beat the game to unlock weapons you can buy that are an enhanced version of the weapons you already own. You can only buy if you have leveled them up all the way already. These cost a lot of bolts but are even more powerful then the level 5 weapons you already have and they can be upgraded another three times making them very powerful.

Go to your side of your ship at the starship phoenix, and activate the machine.

At Star Phoenix’s comic room select chapter and press square. Enter YING_TZU and press start. This will enter the museum where the game is. Note: This doesn't work for the PAL version of this game.

Go to Metropolis and follow the path over and into the first building, then hop up onto the left window sill and break the window, then hop across to the next building. Hop up onto the left side again and break this window, and there's a teleporter. Go to it at 3:00am-4:00am for the Insomniac Mueseum.

At Holostar Studios the second room that is raining (not the graveyard) there is a circular button to your right that will change it from raining to snowing.

If you collect all the trophies, the door in the trophy room will open up, revealing the Insomniac Museum.

Go to any challenge like Annihilation Nation, start the challenge and quit and it refills your ammo and health.

If you have a save from Ratchet and Clank 1, you get a 10% discount on weapons when you buy them. Save must be past the 2nd hoverboard race.

Although you can buy any of these weapons during the game, you can get them free from Slim Cognito on Aquatos at certain times in the game if you have a Ratchet & Clank:Going Commando save file on your memory card. The weapons are, Miniturret Glove, Lava Gun, Shield Charger, Bouncer, and Plasma Coil.

Go to the game system on Starship Phoenix with a vidcomic that you haven't beaten yet. Now select the level of the unplayed vidcomic. Scroll up to the first one and press Up again. If it's the fifth vidcomic then press Up yet again. As long as from the first vidcomic you get back to selecting the latest unplayed vidcomic, press X to play. The game prompts to skip the level. Agreeing will finish the level with no records. In Challenge Mode, it will show no records EXCEPT the best time you got during your first try in the game.

To re-play a completed Hacker puzzle: Stand in front of it, hold R1, then press Triangle.

On the starship phoenix, do to any holographic training, when you enter the training, immediately leave it, your ammo will be full

Once you finish an arena challenge at Annihilation Nation, if there is an Inferno Mode crate laying around, you can trigger it after you win the challenge, and you will still have the effect in the next challenge. The same thing happens with the Rift Inducer/Rift Ripper's votrexes; if you shoot some after the challenge is over (but before the screen goes black) they will still be there when the next challenge starts. This is a good way to do some damage without having to use any ammo, and doing this with an Inferno crate can make single-weapon challenges much easier; as long as you don't try to fire your weapon, you can do them entirely with the wrench. (This does not seem to work with the Suck Cannon/Vortex Cannon challenge; when I tried it, I got a "Out of enemies to use for ammo" message and lost in Round 2.)

Allows you to pass through any wall, forcefield, etc. You need the megaturret (miniturret works too but megaturrets work much better). Place yourself against the wall facing the opposite of it and place very closely 1 to your left and 1 to your right. If done correctly, the screen will start to shake. Now place a megaturrent infront of you very closely and you will either have gone through the wall or the screen is violently shaking. If it is shaking then try to move through the wall by running or charge boots.
