hi

I've recently been playing W&G in project zoo (pc version) and I'm seem to have got stuck.
I am in the section of the volcano where the last gorilla is is hanging over a wide river of lava, there are three targets which I cant hit with any weapon, and I can hear the ringing noise of a tool nearby.
can anybody help me?

I was stuck no that bit too but the game crashed so now I can't do it. Sorry can't help. keep trying and good luck !

ok thank you anyway
