Chopper Attack

Chopper Attack, known in Japan as Wild Choppers, is a helicopter-based third-person shooter game for the Nintendo 64 released in 1997. The game features numerous missions in various locations. Missions include bombing the enemy's bases, escorting Air Force One through dangerous jungle terrain, and rescuing prisoners of war. Every mission has a time limit.

You get to choose between eight different attack choppers, each having its own strengths and weaknesses. After the briefing from your XO, you are set to destroy something —tanks, other helicopters, planes, radars, buildings etc. While the mission only requires you to do something specific, destroying everything gives you bonuses and money, which you can then use to buy more heavy-duty missiles between the missions.

If you look at the screenshots, you might think that Chopper Attack is a helicopter simulation. It's not. Your elevation is fixed. There are no physics. You have boss fights against giant choppers. The game is pure and plain 3D action.
