Use WASD to move and jump, left click to shoot.
Play Armio game and push back the invasion before it destroys the city! Control a hero and use the given gun to shoot down everything including 50 choppers and thugs coming from the dark force. Taking down helicopters is more difficult than killing antagonists. Not only that, these planes will constantly release deadly shots from above while their allies attack around you. You'd better evade to survive. Besides, you will have the chance to increase your score and win faster. Good luck!
