I used to play a lot a game that was absolutely similar to Twin Cobra: the two chopters, simultaneous 2-p action, the add-on weapons, bombs etc.
The main differences were that at the beginning of the game you went across a field and you could shoot at bushes (while Twin Cobra begins across the sea).
Plus, there was a sampled male voice singing in the background music.
Anyone knows the name of this game?
