If you can't connect to any of the servers then the game is probably updating, you will normally hear about it in Game Chat. So before you go rating a game 1/5 because you cannot connect at least ask in chat :)
I just got the 1st hard badge before the medium. On 1948, keep flying forwards and drop the acid until the three fast birds are destroyed, then 180 it and fly back to the big plane, don't get too close, but just make sure to lay more acid in a line in it's path... Easy peasy.
I've experienced two bugs so far. The first was when I had to race against the guy to get the information. The scene about asking and being called 'Sexy' played three times over until I could race. The Second was when I shot my Shotgun inside the safe house. I pressed 'R' to reload and it wouldn't stop reloading, it took all my bullets and put them in the chamber, so Shotgun that didn't need to reload anymore. Apart from that I love this game =D 5/5
If anyone is finding the game difficult, here is a Full Walk Through I made, take a look, it covers pretty much everything.

Just lost a large amount of troops trying to occupy another castle, didn't realize the defenses were so strong, or at least for me. Having around 80k force, I got beaten pretty bad.
I finished my Walk Through, if anyone needs help with anything, it's sure to be in here.

The best way to go about most bosses, is using the Psion Wave, along with the Reflection Barrier, the boss on level 9 is no different, just you Psion Wave on his wings. I'm currently making a full walkthough for this game, I will post the link in about a day.
@liamcooliam25, you cannot sell old weapons. You may as well keep everything as it is, because you get an achievement for buying everything in all three shops.
@Mousekiro, the best way to deal with that boss, and most until about level 17, is to take the reflection shield and psion wave. Just fire the psion wave when you can, and use the reflection shield to deflect a mass of bullets back. And if you have a spare 'micro energy boost' or two, take them with you.
