There is one game I've haven't been able to remember the name of for years now:
- it was for the NES or Commodore 64 (or maybe another platform?)
- top down game
- you play as a helicopter or some sort of airplane that can fly around the the map
- a map would consist of a bunch of different sized islands, with a sea surrounding them
- enemies on the map would be ships in the water, vehicles on the ground, other planes in the sky, and bases with numerous turrets
- I think the objective was to destroy each base on the various islands
- (not sure if this last point is accurate) when playing with a second player, that player could control the various enemy units on the screen and they would try to shoot you down.
