Ratchet & Clank: Up Your Arsenal Tips

Easy Way Through Quarktastic Tournament
There is an easy for you to get through the 100 Battles really quick. You will the Quack-O-Ray to do this though. To get it first you will need to be able to get to Aridia, where Qwark is hiding. I believe it costs 180,000 bolts. Anyway, have this equipped and Qwarktastic Challenge. If the Big Ball with the turret is shooting you then use Nitro Launcher or Rift Inducer around the ball and you will be fine. Just be able to dodge the attacks from the enemy.

Note: Quack-O-Ray cannot be used while jumping or Crouching.
