Ratchet and Clank: All 4 One Alpha Cannon Code Help

Recently I read that there is an inputtable code for Ratchet and Clank: All 4 One that unlocks the alpha cannon. I got info on this site - http://ratchet.wikia.com/wiki/Ratchet_&_Clank:_All_4_One (under 'Weapons and Gadgets'). Does anyone else know much about this?

 

Yea, you should read a little further down that page. It went on to talk about it's appearances in Ratchet&Clank: Future, I saw nothing about it for All4One. Those pages can be edited easily, and it's probably just a prank or mix up. As far as I know, there is no such weapon in the game.
