the only problem with that statement Backyarddefender is this. You can not play hydraulic on kongregate. Only on armor games. So we can not get some of the achievements in the game because of that. That is the pity. Because if we wanted to get those in-game achievements we would have to go to armor games and play it there. Even so it WILL NOT register on kongregate. THAT is the pity about it. :(
the boss run is to hard. I got to the 4th boss not using any or my bombs then I died on that blue boss. How are we supposed to get that last hull if we can not beat the bosses?
