Can not get passed region 9

tbola

Hi just need some tip for Dino Hunter Region 9 on the IPhone. 

I have completed the rifle series and I am now on the trophy hunts. I am on the second hunt which is 2 vipers. I just can’t get passed them at all. I have to use region 9 rifle and even when I try to shoot one I get about 3 shots in before it gets me. What’s best way to get passed these two vipers in the trophy hunt

I have the same problem. A fully upgraded rifle of the 9th region and killing two dinosaurs is simply unrealistic!
