Ok, for this one, you need to be on challenge mode with shock crystal armor. Walk over to
the hut that gets blown up after theget on i training part with that luna girl takin
pictures. Just plant a crystal, then get on it. I'm not sure if you hyper-strike or not,
but you do get over the hut. Have fun ;)

when online in mega cannons go to the edge of the river end to the part whare u fal but
the end the other side with the wall u see to rocks jump tillu get 2 the top where u can
get a wepon upgrade u r surrounded by a wall go to the one with a turrent  u see a edge
and walk in u dissaper

use the shock roket,the pda,the agents of dread(if maxed out),and dual lacerators(if maxed
out.)

Ok, I admit, this might not be as good as you thought, but, none the less, heres how it
goes. First, purchase a bee mine glove, (if you don't have one) and walk over to a corner.
Now, while your as close as possible to the corner, toss bee mines directly in-front of
you. I admit, I have had a bit of trouble with this glitch, but it works. The mines should
push you through the walls. Have fun! This glitch IS usefull sometimes!

you have to where this following armors: sludge mk.9 helmet,wildfire torso,wildfire
gloves,and wildfire boots. enjoy!!!!!!

this is not really a cheat i was just bored & i wanted 2 talk 2 someone. `o´ im sooo bored
idk y i put this im out
