Sky Gamblers: Air Supremacy is a combat flight simulator game. Perhaps the best thing about this game is the number of modes that it has. You can play both online against your friends or offline. There is a campaign mode, but after you are done with that, you can continue playing the quick missions. There are different types of missions: Survival, Free For All, Team Deathmatch, Capture the Flag and Defend the Base. You can also play some of those modes online with your friends, even co-operatively.
The game features two different control modes. The first one, intended for casual gamers, is assisted quite heavily by the CPU. It stabilizes your plane and somewhat limits your movement, but it is incredibly easy to maneuver your plane using this mode. The second mode removes all CPU assists and gives you full control of your plane.
Air Supremacy has a nice In-App Purchase (IAP) system. You can buy a second campaign and unlock other planes by purchasing upgrades. The second campaign is $2.99, and it should add a few hours of gameplay to the game.
In short, I liked the time that I spent playing this game. The graphics are nice, the controls are easy and there are a ton of game modes.
