Help with finding a psx game

When I was younger my twin uncles always played a game on psx. It was a co-op game where the payers play as helicopters shooing at stuff.
If anyone has an idea of what this game is can you give me a name.

Soviet Strike?

err... very nice guess but no, let me specify it more. Its a 2d side scrolling shooter... so yea, I would ask my uncles but there old and senile now...kinda.
If it helps, I think there was one stage that you played as submarines. Sorry if my memory i sketchy Its been exactly 8 years since i played it.

Try every single game found here ;D

Do i really have to go through 300+ games... maybe its my fault because I didnt work on my memory when I was 5 years old...

The closest I could personally find was Strike Point, but that doesn't really sound like what you described. Google is hard to use when you're forced to be vague.

That was a nice guess too, but it was more like the snes version of r-type. I supposed you could just recommended me some good shooting games similar.
