OK i'm stuck here now... where you've just left the beach (where you're using those antlions to attack the bad guys) and you go through the sewer pipes for about 30 seconds, then you're in a place with a bunch of watch towers, and you take the guards out there, then a damn gunship appears... i killed it (i think), and then a SECOND one appears... i can't find anywhere to run away to. i found the crate with all the RPGs, but 99% of the time my RPGs miss the damn gunship anyway.
two things
1) how the hell do i finish this part...
2) is there an easier way to kill the gunships than i know of? what i'm doing is waiting till i get a clear shot, then shooting at them, and like i said, most of the time it misses, and they end up spending 10 seconds trying to shoot it down, as the stupid RPG keeps going in circles trying to find its target. OCCASIONALLY i'll get lucky and hit one.
so how do i beat this thing?
