Great guide, but heads up to anyone reading this. It's kind of a terrible game. I was watching the AngryJoeShow on YouTube and he reviewed this. He was talking about how Battleship: The Movie was longer than the actual game, lol. So that made me want to pick it up for an easy 1,000G. Sure enough it was, but boosting for 200 kills with airstrikes will be very tedious if you don't know what you're doing.
