Helicopter Attack

You are a helicopter pilot trying to survive an endless wave of hostile planes while destroying as many of them as possible.

Luckily your helicopter happens to be armed with air-to-air rockets.

The enemy will fire rockets at you and won't hesitate to collide with you head-on to eliminate you.

Survive as long as you can!
