Ratchet & Clank Future: Tools of Destruction Tips
If you have a weapon that you have upgraded so that you can claim raritanium once you kill an enemy go to Rykan 5 and use it on the sales bots. This is an easy way of claiming raritanium so that you can upgrade. Only go to the places that have got a lot of sales bots. i used the incinerator and i upgraded my weapons in only a few hours (bit difficult for upgrading the weapons that cost a lot of raritanium for upgrade).
