Bombshell, Playthrough, Level "Frozen Paradise", Pt. 1 (Incomplete)

Beautiful level, but long. Lot's of secondary missions that I am trying to complete without increasing the playtime substantially and the size of the video. I could not find the lst crystal and several other items, stopped at a check point as I need some help with this one.. also, did I mention this game is buggy?? :-/ At one point I couldn't fire weapons or bring up the map, had to restart the checkpoint.. sigh..
