Chopper force was a helicopter game published in 1992 by The Fourth DImension
You pilot a futuristic helicopter throughout a number of missions, completing the tasks before moving onto the next one. Each mission has different objectives. You will have to find targets and destroy them, deal with enemy craft, pick up items and move them around and also avoid crashing.
There is a lot of landscape detail: roads with moving cars which stop at the traffic lights and wait for them to change to green, a railway line with moving trains, plus bridges, sheep and many other things as well. You can view the action from inside the helicopter and outside of it, and you can also view the action from different angles. As well as the helicopter sounds, when you fly over roads you can hear the cars and you can hear your pilot breathing (inside cockpit view only).
