It's a flash game i remember playing a week ago You control a little flying machine (which you can upgrade for money) with your mouse. On this machine you can attach different weapons. You must fight the other flying machine enemies and use gravity at your advantage. Also, at one point in the game you must choose between betraying your friends or not.
my point you relpied to a message you souldnt have.
Well the reason why this is an attempt to get points is the lack of description. Their are lots of games like that, which tells me you have no intrest in finding this game.

Not a space shooter, theres no guns, only swords and axes. But you get to fight in the air with little flying machines. It IS on AG In the beginning of the story you are with the good guys (in blue) but at some point you get to fight the bad guys (in red) and the boss offers you to spare your life if you join him.
