If you would care to look at the picture in the ships database of the Avenger, then you will see 2 Mass Driver guns right beside the cockpit, 2 Photon guns above the cockpit, and put the missle(including the 4 torps[there arent any torps launched from the top, I checked in wc4]) launch points in the spot where the black spots in the picture.(btw, the Avenger in the picture is upside down) and the next time someone helps you, be a little more courteous to the helper, that way more people will help you with the next question/problem.
