Ratchet and Clank: Going Commando Unlockables
Mega Weapons and Random Stuff Menu
Complete the game and select the 'challenge mode' option after you have defeated the mutant protopet. It will start the game again but with all of your current bolts and weapons. If you have upgraded any of your weapons you will be able to by the mega version of it. These are far more powerful than the original but will cost a lot. To unlock the random stuff menu simply complete the game.
