Ratchet & Clank: Up Your Arsenal Tips

Fast Weapon XP

Play the Annihilation Nation challenge against Scorpio to rack up experience. Some weapons, like the Shield Glove, may need different stages.

Upgrade the Flux Rifle Quickly

Go to Mylon and get out your Flux Rifle. Go to the end of the platform at the beginning of the level. Then, shoot both of the robonoid commanders. Each shot will upgrade your rifle. If they both die, jump off the platform and start over.

Free Ammo and Health

Go to any challenge, start it, and quit. It will refill your ammo and health. This can save you thousands of bolts.
