Upgrading weapons
If you have low power weapons and wish to put some real firepower into them, go to Sarathos Swamp and do the ''where the laviathans roam'' challenge. Kill laviathans like crazy and your weapon should upgrade. When you get v10 of every weapon, get some bolts, (possible from endzone challenge in the battledome), and buy every mega weapon available in the dreadzone vendor. Then go back to Sarathos and start ripping 'em up again.
This might take some time, buts its the quickest way that i got to every weapon v99.You must be asking, ''what about the holoshield launcher? it stinks at sarathos!''. Well, i'd go to orzon and do the maze. You will find, eventually, and landstalker prauling around with its machine gun shooting at you. Get in the corner in between both doors and shoot out 4 holoshields. right beside each other. The landstalker will shoot the shields like crazy, giving you very quick exp.
ok, now go to sarathose and start off. Good luck!
