I need help with level 6 or 7 on shadowgun
I'm not sure which level is ... I know is between 6 or 7. Is after I get to the part when I get to the evil doctor and he's lean on a bed without brains! Then after that I get to a good part where I can still see speakers and the doctor is saying "I'm the peek of evolution, a new god " and there is 2 zombies and one predator looking with a machine gun... That's the part where I've been stock since yesterday. I've shot all my bullets, on machinegun, rifle, missiles to the point I ran out of bullets and that predator looking still alive. Can someone with experience on gaming and shadowgun please help me, is so frustrating, thanks in advance
