Wow hope the guy didn't use someone's work for his own. In terms of gameplay it's pretty slick for an Iphone app. Controls are pretty basic you have rudder, collective, pitch/roll, machineguns and rockets. The Pitch/roll use the accelerometers in the phone whereas the rudder, weapons and collective have onsreen buttons. Missions are pretty basic with the first few covering basic training like landing, refueling and basic weapons use. Later missions have you attacking terrorists and the like. My real opinion is this game is the closest thing you will get to DCS Black Shark on a phone or portable, and the price is very fair. The creator has mentioned he plans an update for hellfires, multiplayer, and some other updates soon.
