Ratchet & Clank Future: Tools of Destruction Tips
Its quite strange actually. Equip a weapon that has a raritanium upgrade and you've upgraded it so that you can get raritanium from killing enemies. Then go to planet Rykan 5 and use this weapon on the sales bots. Sometimes you will get raritanium. Go to any planet that has alot of these robots and use weapons that you have upgraded to have raritanium from killing them. I used the incinerator and i was able to upgrade my weapons in no time.
