- Completing the Impossible Challenge in the Megacorp Games
The Impossible Challenge consists of 60 rounds. Every five rounds it switches between normal and cagematch modes, and the very last round is against the Megapede. In order to win, do not attempt it until you are very strong and have learned how to strafe expertly. Try doing it when you have reached the end of the game and have all or most of the weapons (and have upgraded them).. Also have your experience meter at least three quarters full so that you can level up near the end of the match. The instant nanotech fillup will help tremendously. Reserve your ammunition, especially the Megarocket Tube (Minirocket Tube upgrade) as you will need it against Megapede. Use the Shield Charger when you are low on life and the Megaturret Glove (Miniturret Glove upgrade), Heavy Lancer (Lancer upgrade), and MiniNuke (Gravity Bomb upgrade) for dealing with enemies when the wrench just will not do. Your prize for winning is 200,000 Bolts and a skill point.
- Easy upgrade
Go to Maktar Nebula and go to the Battle Arena. Play the Impossible challenge. Next, buy all the bullets for all your guns. Then, keep killing the people with the non-upgraded guns. Even if you die, you will get them upgraded. If you die, buy more bullets.
- Jak 2 and Sly Cooper references
At the "Press Start" screen, you will see Ratchet playing video games while Clank reads a book. At first Ratchet is playing both Ratchet And Clank and then Ratchet And Clank: Going Commando. Allow the game to idle and you will see Ratchet playing Jak 2 and Sly Cooper as well.
- Stay on second floor
When you are fighting the Protopet Boss at the Megacorp HQ, shoot him until you get to the second level, when he starts smashing the ground to bring you to the third level. Throw a bomb at him with the tractor beam and he will forget about smashing the ground and come after you. He will not smash the ground for the remainder of the battle. Note: Only the bombs work, as they do lots of damage.
