How, where, and, I repeat, HOW exactly do you get the scarab gun!? my friend told me that you have to lure a banshee in with you into the tunnel at the end of the bridge in metropolis, then while it's saying LOADING...DONE you have to hijack it and fly up to a ledge, but that sounds highly unlikely (i tried it, but it's next to impossible to get hijack it right when it says LOADING...DONE)
