the Gas platform always ended up as a version of WWI for me. the middle platform and connecting two halls were the no man's land. even attempted landings behind enemy lines using air craft were hard to successfully pull off.
Maybe I shouldn't be speaking... but...
Landing on the platforms was easy. Kill the guns on the way, if you stay out of their range, and voila! then make an AA gun, and peg people trying to get to the middle, and poof! everyones across...
