please help me with metroid prime hunters?

Question

I have beaten the first two levels of metroid prime hunters for the nintendo ds on the third and fourth levels I am stuck. I pretty much know where I have to go for both levels but the door thing is being blocked and says that I need a gun that shoots superheated magma for one door and supercooled plasma for another door. I have beaten the other hunter for both levels but can't find these guns to open these blocks on the doors to defeat the main boss and escape and beat the level. SO PLEASE TELl ME WHERE I CAN FIND THESE GUNS OR JUST HOW TO BEAT THE LEVEL. NOCE AGAIN I HAVE ALREADY BEATEN THE HUNTERS BUT CAN'T GO THROUGH THESE DOORS AND DEFEAT THE MAIN BOSS AND ESCAPE THE LEVEL IF THAT HELPS ANY

Answer 1

in some states of america you simply need to open a bank account to have access to one of these type of guns
