The yautja won. The young one at the end. As it's mostly thanks to him the queen was defeated.
A facehugger popping up aboard a ship with experienced and heavily armed yautja is hardly a victory... .
On a secondary note... it was a great movie but what dissapointed me was the fact yet again the humans had the 'survivor'.
I'd rather have seen a lot more aliens fight a squad of EXPERIENCED yautja with heavy weapons like their burners and the likes.
