AviNation's 3D graphics use the Unity engine, making this environment more detailed, and also giving you more options to interact with your growing airport. You can zoom into ground level, rotate the camera in four directions and so on, as you watch individual passengers depart planes, luggage being loaded or deplaned and so on.

A quest system will keep progress moving ever forward, as you'll be able to access dozens of planes, airport buildings and more, using either free or premium currency as is the standard setup for such games. All told, this doesn't appear to be too much of a departure from other simulation Facebook games, except when it comes to the game's use of the 3D graphics engine, a day and night cycle and apparent focus on a storyline. The gameplay appears to be pretty standard for the genre, but of course, that could all change come the game's official launch.

If you're interested in trying out AviNation for yourself, you can jump into the closed beta by logging onto the game's official website, connecting with your Facebook account and then entering code "REDEYE."
