Flaw to Infernox armor cheat
There is a cheat displayed stating that you can keep the infernox armor forever if you simply open the infernox mode box, pause the game, open the skins screen, and select "current armor" I have tried this cheat, and it does however work, but the "fake" armor is only the equivalent to your armor that is displayed on your items screen, which is the last armor that you have purchased, or your "real" armor. The game designers have put this cheat on the game, simply to trick the players who think that they can get the infernox armor for free.
Collecting Sewer Crystals
On planet Aquatos, you have the option of collecting sewer crystals for the plumber and trading them for bolts. When you first get to this part of the game, you can go through a small area and collect crystals, but why not just wait until you get the Magnet Boots before collecting mmost of them? When you wear these boots, you can access much more of the entire area. They allow you to walk on walls and ceilings, dodge enemies, collect more crystals, and even go through hidden tunnels on the ceilings and walls. By waiting to this point, it helps you stay alive while you collect tons of these crystals to trade for cold hard bolts!
Upgrade Flux Rifle Quickly
First go to the planet Mylon and then get out your flux rifle. Then go to the very end of the platform at the very beginning of the level. Next shot both of the robonoid commender's.

Just keep doing this till it is upgraded all the way.

The very cool and special Insomniac Museum is a hidden planet in the game where those skilled and lucky enoughcan go to check out some very cool extras, cutting room floor materials, minigames, effects, animations, weapons, etc., via a detailed and 3D rendered replica of the Insomniac Games' offices. There are two ways to get into the Insomniac Museum:
1. The first is to collect all of the games 15 trophies. Once all have been collected the locked door inside the Trophy room at Phoenix will be open. Just walk in and you will be whisked away into the museum.
2. The second way to get into the museum is via a special teleporter on Metropolis. The pad can be found through the window on the left, before the swing target leading to the level's first Titanium bolt. The teleporter is typically not operational but, if you return to it when all good "Insomniacs" are awake-between 3:00-3:59 AM.
