Fast Weapon XP
Need easy stages to get weapon experience? Play the Annihilation Nation challene against Scorpio to rack up the XP. Some weapons, like the shield glove, may need different stages to gain XP. For the shield glove, try playing the battle missions in Marcadia and having the bevy of peons shoot your shield for XP.

Upgrade Flux Rifle Quickly
First go to the planet Mylon and then get out your flux rifle. Then go to the very end of the platform at the very beginning of the level. Next shot both of the robonoid commender's. It will take some time to beat them but each shot upgrades your rifle to the v3. Then it takes 2 shots. If they both die (they will)just jump off and start over. Just keep doing this till it is up graded all the way (this will take tops 2 min.).

Free Ammo and Health
Go to any challenge like Annihilation Nation, start the challenge and quit and it refills your ammo and health. This will save you thousands of bolts.

Override Weapon Switch in Arena
When fighting in the battle arena you will come upon matches where you weapon will auto switch after a few shots. To avoid this follow these steps. Start firing of shots till you get the hurricane. When it is out simply hold the fire button and don't let go or do a clank double jump and you will continue to fire the hurricane even though the weapon in you selector block will say something else. I find this easiest to do if you switch to lock-strafe-mode and then hold down R1 (fire).
