The Apple App Store offers downloads of Dogfight Elite for iPhone and iPad for free. That’s $2 off and the best deal we’ve seen for this multiplayer WWI & WWII combat airplane simulator.
Dogfight Elite is a World War I and World War II massive combat airplane simulator. In Dogfight Elite you can fly an airplane, drive a tank or jump out of the plane and defend your position as a soldier. You can also play alone and fly through training levels all the way up to full-blown dogfights against enemy planes.
