If you already play World of Tanks on a regular basis, the new title hopes to entice you with the new unified account system for both games, allowing you to enjoy some premium bonuses in both titles rather than just in the one. While there's no direct integration between the two (your plane can't fly in and strafe some tanks, for examples) it's still an incentive to get players into the same cockpit that 4.5 million beta testers sat in. So take to the skies, would-be pilots! Then shoot everything else up there that moves, including ducks. Especially ducks.
