Ok this is really REALLY weird if you don't have the electrick shock upgrade thing for your guns stinks for you
#1 switch to a gun with a electrick shock upgrade

#2 go to the arena where you fight chainblade

#3use that gun at the end of the battle or the hole match if it's good anofe to do it

#4 kill chain blade (NOTE: it might not electrify him when he is dieing making him not blue) but if you shot him towrds the end of his life spand he should be shocked and turn blue then die

( if you ever fight chain blade again he will be blue forever Only and I mean Only if you don't beat the game and chose to do challenge mode or restart so don't beet the game)

Happy blue chainblade wii nut =]

Rounds 1-9: Just pull out your Gravity Bomb and "bomb" every group, kill the crap
Out everything else with your Blitz Gun(if you have it). Round 10(Chainblade): Use your Bomb Glove(If you got it from Barlow) on him when HE IS ON THE GROUND not when he is in the air throwing his swords at you. Speaking
Of throwing his swords at you, jump when he DOESN'T throw his sword and finish the double jump when he does throw his swords at you. You should have at least 23/40 ammo when you beat him. Otherwise, shoot him 4 times with the Vaporizer.

To beat the protopet fast, get the bouncer, upgrade it to the heavy bouncer, and shoot it at him, it takes out a huge chunk of his health.

Press Rl and L1 at the same time and you will be teleported to a different area of the place you are flying your ship.

Ok to do this go into first person camera,look straight down at the ground,
Jump,and throw your wrench,very fast.Keep throwing it and you should levitate.
This is very helpful because you can go over water and climb walls with this.

If get the shock mod for a weapon and use it on a boss a lot,they will turn BLUE!!
Same thing with the acid mod but they will turn GREEN!!!

Ok. This is more of a glitch than a cheat,but I didnt know were to put it.
NOTE:must beat game.

First,select first-person mode.

Go up to a wall, double-jump and start rapidly pressing square.

You'll start scaling the wall.

You can do this with most walls.

1-take out one weapon
2-take out another weapon
3-double click triangle and you should go to the last weapon used

This does work, and it a useful way to switch from 2 weapons really quickly!

Win the "Impossible Challange" at Megacorp Games in the battle arena.

Note: Turn the cheat on/off in the "Special"menu.

While your fighting the Protopet Boss at the protopet HQ, you can stay on the second floor by using your tractor beam to hit him with one of the bombs.

He won't trash the floor but he will start to come after you.

P.S. You should use the bombs these will do the most damage....
