Protect your base and destroy the enemy with your helicopter in this hybrid tower-defense game. Unlike Arnold Schwarzenegger, you aren't fighting aliens, but the hostile enemy still needs a good butt-kicking. Hover your chopper over turrets to get them up and running. Fly over the first-aid kit and the upgrade facility for a little help when you can. In the meantime, steer your helicopter around the map, destroying enemy tanks and jeeps before they can damage your base.
