Answer from: Rahul
Snow 66. Hit on the 4th log, around one cm above its bottom edge to get the bullet to hit the explosive drum. I need help on Forest 58, wild west 91 and Lab 98 !

Thanks. I had actually figured out snow 66 a couple weeks ago. The funny thing is that I still can't get 3 stars while using the girl, but when using the man I can get it almost everytime. Wild west 91 - you have to shoot down and to the right maybe 3 mm. or so from your foot. This took me alot of tries to get it right as most of the time the bullet will hit the cart the zombie is riding in without killing him. After fine tuning your aim you should get it. Lab 98 - This one gave me alot of trouble until someone on this site helped me. He said to shoot down and to the right about 2 mm. from your toes and it will bounce up thru the portal and hit the top two zombies. This worked for me but I noticed it is even closer than 2 mm. You have to shoot very close to your toes almost hitting them. I just did this level again and it still takes me alot of tries to get it right. Forest 58 - Good luck with this one. It's the only level that I don't have 3 stars on.
