Wolf kills a dozen or so aliens while the town gets overrun with what? Hundreds? Thousands?
Needless to say, he failed his mission horribly, but fans say he's the best thing about the movie.
The first AVP clearly states that if aliens ever got out of control, the predators would blow up everything, making sure that nothing survives. Why doesn't Wolf do that here?
It would've made more sense if Wolf were there just for the predalien.
