That's not my issue. I was not able to get a single one. As I said, they are literally impossible at the speed it's going at unless the X is right in front of the turret to begin with, and even when it is nearly right in front of the X, I click to shoot immediately and sometimes the shot doesn't even reach the X before the next ad pops up. The last time I played, I finally nearly hit my first ad. :( Maybe it's browser related? I might try later on different browsers.
