With your gunship, save lives. Challenge the enemies.
Terrorists invaded the city of New York.
The US military command, sent with your over-armed helicopter rescue the hostages who take refuge on rooftops.
Your mission is to save as many hostages. Be careful, if you miss more than three hostages, your mission fails.
By cons you'll excuse if you save in more than five in a row.
You should also avoid missiles and enemy aircraft, you have the opportunity to defend you, thanks to your missile launches, you will also weave between buildings.
Good luck to you.
