From the (slightly misleading) Store description:
Air Gunship 3D is a super action game where you ride a helicopter and shoot down all incoming enemies before they destroy you. Don’t take this mission lightly, the sky will be full of incoming heli shooters, so you need to be careful else all hell will break loose and your operation will end in a chaos. Download Air Gunship for free today and take charge of your cavalry in the skies.
Features:
+ High quality air battle scenes to completely immerse you in the game play
+ 3D Helicopter simulator with varying powers and ammunition like laser guided missiles, super sonic rocket launchers etc.
+ FPS shooter game like experience for endless fun
+ HD quality graphics for realistic feel.
The scope of the game isn't quite what you might think - the action always takes place in the same part of the virtual world, albeit with some nice mountain peaks to hide behind when there are lots of enemy aircraft around. Plus it's essentially a 'how long can you stay alive' game - your score is the number of waves of enemy craft you manage to shoot down before you succumb.
Add to that a flight model which is deliberately simplified to avoid each user having to learn how to fly a helicopter, your craft is automatically stabilised and brought to a stop anytime you let go of the thrust control. But don't be too put off, the result is still playable and fun, even if there's ultimately not huge depth to the title.
