Easy Bolts Use the following trick to get the Bolt Multiplier to 20X and earn lots of Bolts. To do this, you must have completed the game at least once so that you are in Challenge mode. Go to the Battle Arena on Planet Mukow, and choose the "They Were On Sale" fight (with the hundred bomb bots). Once the battle has starts, use a Mr. Zurkow, then start throwing the Nano Bugs (small turrets that shoot bugs). Next, use any weapon to kill what does not die from the turrets. The Pyrocitor is recommended if it is level 6 or above. Do this three times for your Bolt Multiplier to be at 20X and get lots of Bolts.

Climb any wall You can climb just about any wall using the Razor Claws, or any version of them. Walk up to a wall. High jump (keep R2 held), then attack the wall with the claws, and quickly jump again. Repeat this as many times as desired. If done correctly, you should be climbing a wall that you are not supposed to be scaling.
